Poll: The Cardinals’ Center Field Battle
As the Cardinals look to embrace a youth movement in John Mozeliak’s final year at the helm of the club, their inability to trade Nolan Arenado this winter has caused some complications. With Arenado ticketed for everyday playing time at third base, St. Louis now has five players for three spots in the lineup: second base, left field, and center field. While none of those five players can play all three of those positions, the versatility of Brendan Donovan to play either second base or left field connects the decisions made in the outfield to those at the keystone.
Donovan and Lars Nootbaar are both more or less guaranteed everyday playing time with the Cardinals, and one of them figures to be the club’s starting left fielder. Should Donovan start in left field, it would push Nootbaar to center, and that would open up second base for Nolan Gorman, who would have taken over for Arenado if the veteran were traded. Meanwhile, starting Nootbaar in left would push Donovan back onto the infield, and in doing so would open up center field for one of Michael Siani or Victor Scott II.
Scott and Siani are very similar players. Siani is a little over a year older than Scott, headed into his age-25 season while Scott has only just turned 24, and the pair combined for nearly 85% of the club’s innings in center field last year. Both are left-handed hitters who have struggled to hit in the majors so far, but are very well-regarded for their speed and defense nonetheless.
Of the two, Siani has the edge in terms of big league experience. After brief stints in the majors with the Reds and Cardinals in 2022 and ’23, Siani enjoyed his first extended taste of big league action last year when he appeared in 124 games for St. Louis and stepped up to the plate 334 times. He hit a paltry .228/.285/.285 in that time, good for a 64 wRC+ that was 36% worse than the league average hitter and the eighth-lowest slash line among hitters with at least 300 plate appearances. With that being said, Siani went an excellent 20-for-23 on the basepaths while posting +16 Outs Above Average, a 99th percentile figure that placed him behind only Nationals defensive standout Jacob Young among outfielders.
Unfortunately, there’s little in Siani’s profile that suggests a significantly higher offensive ceiling than he demonstrated in 2024. His actual batting average and slugging percentage both outstripped his expected numbers in those categories by more than 20 points last year, and his .322 BABIP, while not necessarily unsustainable due to his excellent speed, is already at the higher end of the expected range for a regular player. That limited offensive ceiling could open the door for Scott, a consensus top-100 prospect entering last season who has previously shown flashes of offensive potential in the minor leagues. Scott’s .179/.219/.283 (40 wRC+) slash line in 53 games for the Cardinals last year was actually worse than that of Siani, though his peripheral and expected numbers suggest the pair’s underlying performance was roughly the same.
Most notably, Scott flashed more power potential than Siani with a 5.7% barrel rate during his time in the majors last year that more than doubled Siani’s 2.3% figure. Scott also had 35 hard-hit batted balls to Siani’s 43 despite being afforded less than half of the playing time. All of that, as well as Scott’s excellent .323/.373/.450 slash line at the Double-A level in 2023, suggests that Scott has a higher offensive ceiling than Siani and could be a more impactful all-around player if given the opportunity. Scott is also a potential game changer on the basepaths, having stolen an unbelievable 94 bases between High-A and Double-A in 2023 and having followed that up with 35 steals between Triple-A and the majors last year.
Scott grades out extremely well in center field on scouting reports and posted solid (+3 OAA) numbers in defensive metrics with relatively minimal playing time last year, but he would need improve those numbers substantially to offer the sort of league-leading defense Siani has shown himself to be capable of. What’s more, Scott’s bat took a concerning step backwards even at Triple-A last year, when he slashed just .210/.294/.303 in 82 games. That lackluster showing could suggest that Scott simply isn’t ready for another jump to the major leagues, particularly given that the gap between MLB and Triple-A is even bigger than that between the Triple- and Double-A levels.
Of course, another viable option would be simply placing Nootbaar in center field. An above-average big league hitter in each of his four MLB seasons so far, Nootbaar is obviously the most talented hitter of the bunch but will be in the lineup in some capacity regardless of whether he’s playing center field or not. Playing Nootbaar in center, then, would actually open up playing time for Gorman. The club’s first-rounder back in 2018, Gorman was a league average bat during his rookie season in 2022 before taking a big step forward the following year, slashing .236/.328/.478 with 27 homers and a 118 wRC+ in 119 games that year. Unfortunately, things fell apart for Gorman last year as he struck out at a worrisome 37.9% clip and watched his slash line plummet to a lackluster .203/.271/.400 (87 wRC+).
Even last year’s subpar offensive output is likely better than what can be expected from either Siani or Scott this year, but to get Gorman’s bat into the lineup the Cards would have to sacrifice on defense. Nootbaar has logged 109 games in center field over the course of his career, with a rather pedestrian +1 OAA during that relatively sporadic playing time. While it’s possible that Nootbaar’s numbers could tick up with more regular playing time at the position, it’s clear he lacks the impactful defense ability of Siani or Scott. The club’s baserunning would suffer if Gorman replaced Siani or Scott in the lineup as well, as Gorman has never swiped more than seven bags in a season and has been a net negative on the basepaths throughout his career according to FanGraphs’ BsR metric.
How should the Cardinals handle their center field conundrum? Should they stick with Siani’s elite glove despite his lackluster offense? Pass the baton to Scott despite questions about his offensive ceiling thanks to his elite speed and baserunning abilities? Or should they slide Nootbaar over to center despite pedestrian defense in order to maximize their lineup’s potential by making room for Gorman? Have your say in the poll below:
Who should play center field for the Cardinals in 2025?

Victor Scott II 60% (2,106)
-
Lars Nootbaar 32% (1,140)

Michael Siani 8% (280)

Cardinals To Activate Steven Matz From 60-Day IL Tomorrow
The Cardinals are poised to activate left-hander Steven Matz from the 60-day Injured List tomorrow, manager Oli Marmol told reporters (including Jeff Jones of the Belleville News-Democrat) earlier today. A corresponding 40-man roster move won’t be necessary after the club’s recent losses of outfielder Tommy Pham and right-hander Shawn Armstrong on the waiver wire opened up 40-man space, and tomorrow’s roster expansion means a corresponding active roster move also won’t be necessary.
Matz’s return to action after a four-month layoff due to back issues that were aggravated further by a setback during his first comeback attempt back in June. He’s now made six outings at the Triple-A level this month without any further setbacks, however, and has pitched to decent results with a 4.29 ERA and 18.9% strikeout rate in that time. Now, Matz appears ready to step back into the Cardinals’ pitching staff, though it’s not entirely clear yet whether he’ll do so as a starter or a reliever.
The 33-year-old southpaw has experience in both roles but has mostly been a starter throughout his career, including in his six starts early in the year before being sidelined by injury. He’s maxed out at 85 pitches in the minors to this point, suggesting he’s stretched out enough to take a role in the rotation, but the club’s rotation is already full at this point with Sonny Gray, Erick Fedde, Andre Pallante, Miles Mikolas, and Kyle Gibson all currently pitching as starters. Pallante has pitched in relief before and is the least experienced of the group, but he’s arguably been the club’s best starter since the All-Star break with a 3.29 ERA and 3.34 FIP in his past seven starts.
If the club wants to use both Matz and Pallante in the rotation, other possibilities include moving to a six man rotation or moving Mikolas, who has struggled to a 6.12 ERA over his last eight starts, into a bullpen role. Of course, the impending return of veteran righty Lance Lynn from the injured list figures to further complicate St. Louis’s rotation picture, giving them plenty of options to sort through in the coming days.
Matz won’t be the only player joining the Cardinals’ roster tomorrow, as they’ll need to add another position player to their mix when rosters expand as well. That player could be center fielder Michael Siani, who Jones describes as a “strong candidate” to be activated tomorrow. The 25-year-old has been shelved due to an oblique strain for almost the entire month of July but is currently in the midst of a rehab assignment and appears to be on the verge of returning. The game where Siani was injured brought to a close a 12-game hitting streak during which he raked to the tune of a .432/.488/.460 slash line while playing his typical elite defense in center and going 4-for-4 on the basepaths.
That sort of electric play has been sorely missed by the Cardinals in recent weeks, as they’ve put together a lackluster 11-14 record in his absence while relying on Victor Scott II to cover center field. Scott has been decent enough at the plate since returning to the majors for the first time since his disappointing cup of coffee to open the season, but his .243/.274/.400 (86 wRC+) slash line in August hasn’t compared to the fantastic stretch Siani was in the midst of prior to his injury.
Cardinals Notes: Matz, Lynn, Siani
Veteran lefty Steven Matz has missed most of the 2024 season due to back issues, including a setback in his rehab back in June as he was building up his pitch toward a return to the big leagues. Fortunately for the Cardinals, however, it appears the southpaw is once again nearing a return.
As noted by MLB.com’s John Denton, manager Oli Marmol told reporters yesterday afternoon that Matz, who had pitched four scoreless frames on 76 pitches the night prior, was nearing a return to the big leagues. Lynn Worthy of the St. Louis Post-Dispatch added that the Cardinals currently plan to have Matz return to St. Louis to be evaluated by the team’s medical staff before they decide whether or not he should return to the big league staff immediately, though (per Denton) Marmol indicated that the veteran is likely to make one more rehab start before returning to the majors.
The 33-year-old could provide some relief for a rotation that has struggled somewhat this season, with only Sonny Gray providing consistently above-average performances. Gray has posted decent results with excellent peripherals as the club’s top starter, with a 3.93 ERA (109 ERA+) and a 3.14 FIP in 22 starts this year. Andre Pallante has been another bright spot, impressing in 13 starts this year with a 3.75 ERA and nearly-matching 3.76 FIP since entering a rotation role in late May despite a lackluster 18.8% strikeout rate in those contests.
Looking beyond that duo, however, the results have left much to be desired. Miles Mikolas has posted a 5.41 ERA that’s 21% worse than league average by ERA+ and is the worst figure he’s posted in a season since returning to stateside ball in 2018 following a stint in Japan, while Lance Lynn had struggled to a 4.78 ERA with a 4.66 FIP in his last ten starts before going on the injured list with right knee inflammation at the end of July. St. Louis had spent much of this season leaning on Kyle Gibson for back-of-the-rotation consistency and attempted to fortify their rotation by adding Erick Fedde at the trade deadline, but the pair have posted ERAs of 6.11 and 5.63 respectively since the calendar flipped to August.
Of course, Matz is hardly a sure bet to provide quality innings out of the rotation himself. The lefty’s Cardinals tenure has been a bumpy one, as he posted a 5.25 ERA in 48 innings during his first season with the club and followed that up with a 5.72 ERA in his first ten starts last year. Those struggles ultimately left him demoted to the bullpen last summer, though he managed to pitch his way back into a rotation role down the stretch and posted excellent numbers (a 1.84 ERA and a 31.2% strikeout rate) in seven starts after being reinstated as a starter. That strong finish last year left plenty of reason for optimism regarding Matz entering this year, but in six starts before being sidelined back in May he struggled badly with a 6.18 ERA.
While some of those difficulties can surely be attributed to the small sample size and an inflated .362 BABIP posted by Matz’s opponents this year, that Matz struck out just 13.7% of batters prior to going on the shelf is cause for at least some concern. If Matz looks good upon his return, it’s easy to imagine him sticking in the club’s rotation mix for the rest of the season, although it’s also possible he’ll find himself back in the bullpen at some point.
Lynn’s impending return, which could potentially come even more quickly than that of Matz, also figures to play a role in the Cardinals’ rotation decisions. The veteran right-hander has been sidelined for nearly three weeks by knee inflammation but is slowly approaching a return to action, with Marmol telling reporters (including Worthy) that Matz is expected to throw a live bullpen session early this week. That’s a notable step forward for the 37-year-old, particularly because Marmol left the door open (as noted by MLB.com’s Injury Tracker) for the righty to return to action later in the week without a rehab assignment if his upcoming session goes well.
With both Lynn and Matz seemingly nearing returns to action, the Cardinals figure to have an excess of rotation options from which they can decide how best to line up for the stretch run as they look to push their way back into postseason contention after going just 4-10 so far in the month of August. In addition to the pitching reinforcements the club expects to get, Denton notes that the club’s run prevention apparatus could be getting a lift in center field in the near future as standout defender Michael Siani has already resumed swinging a bat after being sidelined by an oblique strain just two weeks ago. Siani recently received a platelet-rich plasma injection in his abdomen to aid his return to action, which could come before the end of the month if he continues to progress quickly.
Cardinals To Place Michael Siani On Injured List, Recall Victor Scott II
2:14pm: The Cardinals have officially announced Scott’s recall and Siani’s placement on the 10-day IL due to a right oblique strain. A timetable for Siani’s return has not yet been made clear, though Woo suggests it sounds as though his injury is “significant.”
1:13pm: The Cardinals are recalling center fielder Victor Scott II ahead of today’s series finale against the Cubs, according to a report from The Athletic’s Katie Woo this morning. Woo suggests that Scott will take the place of center fielder Michael Siani on the active roster as he heads to the 10-day injured list due to an oblique issue that cropped up during yesterday’s game.
It’s an unfortunate turn of events for Siani, 25, as he was in the midst of establishing himself as long-term option for the club in center when he exited yesterday’s game due to tightness on his right side and was sent for an MRI as noted by MLB.com’s John Denton yesterday. The results of that MRI are not yet clear, though the center fielder evidently will require at least a ten day stint on the shelf to recover. Yesterday’s shortened performance ended a fantastic hot stretch for Siani that dated all the way back to June 24. In his previous 31 appearances entering yesterday’s game, the center fielder had slashed a phenomenal .354/.391/.415, though that stretch of offensive success came with an eye-popping .492 BABIP that was clearly unsustainable.
Still, Siani’s growth as a hitter has been impressive considering the fact that he entered the month of May with a ghastly .128/.244/.179 slash line. His improved play since then has brought his wRC+ up to 79, a figure that’s still well below average but is enough to make him a viable regular in conjunction with his elite defense in center field and a strong 14-for-17 track record on the basepaths. Siani’s +15 Outs Above Average ranks second among all center fielders behind Jacob Young and fourth among all MLB players this year, while his +10 Defensive Runs Saved ties him with defensive phenoms Pete Crow-Armstrong and Michael A. Taylor for sixth among all outfielders.
Taking Siani’s place on the Cardinals’ active roster is Scott, a fellow glove-first center fielder who bats from the left side. Scott made his big league debut earlier this year as the club’s surprising choice for Opening Day center fielder but struggled badly in the role with a brutal .085/.138/.136 slash line (-22 wRC+) in 21 games before he was ultimately optioned back down to Triple-A. Scott’s struggles have continued in the minors as he’s hit just .219/.302/.319 in 74 games at the highest level of the minors this year despite an impressive strikeout rate of just 14.3%.
It’s not currently clear if Scott will take over for Siani as a regular fixture in center field or will instead be used as a defensive replacement off the bench. After all, the club could utilize either Lars Nootbaar or Tommy Pham in center field and both players would be a significant offensive improvement over Scott at the position. Such a set up would likely leave Brendan Donovan to move from second base into an outfield corner to open the keystone up for Nolan Gorman, who has struggled to a .199/.272/.408 slash line (91 wRC+) in 99 games with the club this year. It’s also possible that Scott’s call-up to the majors could indicate that Siani’s injury isn’t likely to require a major absence, as Derrick Goold of the St. Louis Post-Dispatch suggested yesterday that a lengthier absence for Siani could lead the Cardinals to try and work a right-handed bat such as Luken Baker or even former top prospect Jordan Walker into their predominantly left-handed bench mix.
Cardinals Notes: Arenado, Siani, Contreras, Nootbaar
TODAY: Arenado received a pain-killing injection in his forearm today, Marmol told John Denton and other reporters today. It isn’t yet clear if Arenado will need an IL stint, but he wasn’t available for pinch-hitting duties in today’s game.
JUNE 22: Cardinals star Nolan Arenado departed the club’s win over the Giants in the eighth inning today due to discomfort in his left forearm, as noted by MLB.com’s John Denton. Notably, that’s not the same arm that Arenado suffered an elbow contusion on after being struck by a pitch from Marlins right-hander Huascar Brazoban earlier this week. More information was not made available following tonight’s game beyond the fact that Arenado would be evaluated further tomorrow.
It’s an unfortunate turn of events in the midst of what has been a difficult season for the 33-year-old veteran, who is slashing just .260/.315/.375 with a 99 wRC+. That would be Arenado’s first below-average offensive performance in a 162-game season since his rookie campaign back in 2013. He’s paired that lackluster offense with surprisingly pedestrian glovework at third base, where he’s been worth +0 Outs Above Average and -5 Defensive Runs Saved. That’s a far cry from the fielding he offered at the position earlier in his career, when he won the NL Gold Glove award at third base in ten consecutive seasons from 2013 to 2022.
Even with that diminished production this year, however, the loss of Arenado would still be a tough blow for the Cardinals should he end up missing time due to his injury. Not only is he just two seasons removed from a campaign where he was a finalist for the NL MVP award, but the eight-time All Star is the club’s only clear solution at third base given the present construction of the lineup. While former top prospect Jordan Walker came up as a third baseman and is currently in the minors, the 22-year-old has struggled both in Triple-A and at the big league level this year and converted to the outfield full time last year making him an unlikely choice to take over for Arenado in the case of an injury.
Super-utility bat Brendan Donovan has played the hot corner at times, but he’s settled in as the club’s regular left fielder in the absence of Lars Nootbaar. It’s possible that Donovan could slide over to third base and open up left field for Dylan Carlson, but perhaps a more likely scenario would see the Cardinals rely more heavily on bench bats Brandon Crawford and Jose Fermin to fill in for Arenado at third. That’s especially true given the fact that center fielder Michael Siani also exited today’s game due to an injury, though Jeff Jones of the Belleville News-Democrat relayed after the game that x-rays on Siani’s ribs after he hit the ground hard on a diving play in the outfield came back negative. The 24-year-old appears to have avoided a major injury, but even a day-to-day issue would at least temporarily weaken the club’s outfield depth noticeably.
As for Nootbaar, the 26-year-old has been sidelined by an oblique strain since the end of May. Jones relays that he appears to be making progress in his rehab but the outfielder has not yet even begun to take batting practice, instead only hitting off a tee at this stage in the process. That would seem to indicate that Nootbaar, who will surely require a rehab assignment before he can return to action, isn’t going to be returning to the club’s positional mix any time soon to provide Marmol additional flexibility as he fills out the club’s lineup card in the wake of Arenado’s and Siani’s possible injuries.
One piece of good news for Cardinals fans is the impending return of star catcher Willson Contreras, who Marmol told reporters (including Jones) will catch seven innings for Triple-A Memphis tonight before DH’ing tomorrow’s game. As Jones notes, Contreras caught for the Redbirds yesterday and Marmol acknowledged that seeing how the 32-year-old held up after catching back to back games was the last major box the club needed to check regarding Contreras’s rehab.
Contreras has been out since early May with a broken forearm and was initially expected to miss ten weeks due to the injury, but the backstop has long since clearly been ahead of that schedule and seems like he could factor into the club’s plans before the end of the month. The slugger posted an excellent .280/.398/.551 slash line in 31 games for the Cardinals this year before being sidelined by the injury and could provide a boost to an offense that has posted a collective wRC+ of just 95 to this point in the season.
Tommy Edman To Open Season On Injured List
After casting doubt on Tommy Edman‘s availability for Opening Day earlier in camp, the Cardinals confirmed Thursday that their expected center fielder will open the season on the injured list. Manager Oli Marmol announced to the Cardinals beat that Edman will be shut down from hitting entirely for the next week, as it’s still causing him pain in his surgically repaired wrist (X link via Katie Woo of The Athletic). It’s still not clear whether left fielder Lars Nootbaar, who’s been slowed by a pair of fractures in his ribcage, will be cleared for Opening Day. Marmol added this morning that Nootbaar will be reevaluated Saturday (X link via John Denton of MLB.com). He’s been engaged in limited baseball activities for the past week.
Edman, 28, has primarily been a middle infielder in the past but handled himself well in 310 innings of center field work last season, drawing plus grades from metrics like Defensive Runs Saved and Outs Above Average. Defensive versatility has been one of his calling cards since he debuted in the majors, as he’s played every position other than catcher, first base and pitcher — drawing positive defensive marks everywhere he’s been.
With top shortstop prospect Masyn Winn on the cusp of MLB readiness, the Cardinals’ plan has been to move Edman to center field. Veteran Brandon Crawford was brought in as a veteran contingency plan at short in the event that Winn struggles, further cementing Edman’s role in the outfield, where he’d be flanked by Nootbaar and slugger Jordan Walker — in the event that all three are healthy.
That won’t be the case to begin the season. Edman, who missed time in 2023 with inflammation in his right wrist, continued to play through discomfort even upon returning from the injured list in 2023 and wound up undergoing arthroscopic surgery in October. The wrist injury could well have contributed to a decline in production at the plate; Edman hit .265/.324/.400 (106 wRC+) in 630 plate appearances in 2022 and got out to an even stronger start in April 2023 before his bat cratered. He was hitting .265/.339/.480 through early May but slipped to .244/.298/.378 over his final 418 trips to the plate. Edman finished out the season about eight percent worst than league-average, by measure of wRC+, with an overall batting line of .248/.307/.399.
With Edman now ruled out for Opening Day, it could be Dylan Carlson getting the nod in center field. The switch-hitter has been the subject of trade rumors for much of the past year, but the Cardinals never found an offer to their liking and will now at least temporarily turn center field back over to the former top prospect. Other outfield options on the 40-man roster include slugger Alec Burleson and defensive-minded Michael Siani.
It’s also possible that Victor Scott II, who stole a staggering 94 bases between High-A and Double-A last year, will crack the Opening Day roster. He’s had a big showing in camp, hitting .370/.469/.444 with four steals in 32 plate appearances, but Scott has also yet to play a single game above that Double-A level at which he topped out in 2023. Scott is regarded as a plus-plus defender in center field with 80-grade speed and negligible power. If he makes the club and Nootbaar joins Edman on the injured list, the Cards could put Scott’s glove in center and slide Carlson over to left field.
There are a fair number of moving parts in the St. Louis outfield mix, which has become typical for the organization over the years as they’ve struggled to retain any kind of long-term continuity in the group. Scott’s performance and Nootbaar’s health will be key storyline for the Cardinals in the final couple weeks of camp. Scott would need to be selected to the 40-man roster if he wins a spot on the Opening Day squad.
Cardinals Select Irving Lopez
The Cardinals announced a series of roster moves today, recalling outfielder Michael Siani and selecting the contract of infielder Irving Lopez. In corresponding moves, third baseman Nolan Arenado was placed on the 10-day injured list due to back spasms. Catcher Willson Contreras also landed on the 10-day injured list due to left wrist tendinitis, a move that was reported on yesterday. To open a 40-man roster spot for Lopez, outfielder Dylan Carlson was transferred to the 60-day injured list.
The Cards are 67-86, putting them in last place in the Central. There’s little incentive for veterans like Contreras or Arenado to play through nagging injuries at this point, so they will get an early start on the offseason by sitting out the last handful of games. It was reported last week that Carlson would require ankle surgery, making his transfer to the 60-day injured list unsurprising.
As those players rest, it will open an opportunity for Lopez to make his major league debut. The 28-year-old was a 19th-round pick of the Cards in the 2017 draft. He has split this year between Double-A and Triple-A, hitting a combined .260/.368/.420 in his 346 plate appearances with a 12.4% walk rate and 19.1% strikeout rate.
He’ll give manager Oli Marmol a multi-positional option for the final games of the schedule. He has played all four infield positions this year, as well as the outfield corners and even made an appearance on the mound.
Cardinals Claim Michael Siani From Reds
Both the Reds and Cardinals have announced that St. Louis has claimed outfielder Michael Siani off of Cincinnati’s waiver waire. Siani was designated for assignment earlier this week, as part of the 40-man roster maneuvering necessary when the Reds claimed Hunter Renfroe and Harrison Bader off waivers. The Cards also announced that Guillermo Zuniga has been moved from the 15-day injured list to the 60-day IL, thus ending Zuniga’s season.
A fourth-round pick for the Reds in the 2018 draft, Siani is a veteran of 12 big league games — nine in 2022 and three for this year’s team, with four hits over 25 total plate appearances. Siani is known for both his outstanding defense and speed, as he has stolen 155 bases in 200 total attempts in the minors while also showing excellent glovework in center field. With a .228/.344/.355 slash line over 2167 PA in the minors, offense is still a work in progress for the 24-year-old, even if his other tools project him as at least a bench option at the MLB level.
While it isn’t a surprise to see another team claim Siani away, Jeff Jones of the Belleville News-Democrat (X link) notes that it is a bit of a curious pickup for the Cardinals in particular, given that St. Louis already has several outfielders on the 40-man roster or on the cusp of the majors. Of course, a team isn’t just going to pass on a player it thinks has promise, and the Cardinals might clear some space anyway in the outfield this winter. The team is widely expected to try and trade some of its current outfield mix, likely in search of some badly needed reinforcements for the starting rotation.
Zuniga was first placed on the IL on August 25, and since he is suffering from a right forearm strain, it already looked like he probably wasn’t going to make it back before the end of the 2023 campaign. The only hope is that the 60-day IL placement isn’t a precursor to a more serious injury like UCL or elbow damage resulting in surgery, as such a procedure could potentially shelve Zuniga for just about all of the 2024 season. Zuniga made his MLB debut this season, appearing in two games for St. Louis prior to his forearm strain.
Reds Designate Michael Siani, Alejo Lopez For Assignment
The Reds announced Thursday that they’ve designated outfielder Michael Siani and utilityman Alejo Lopez for assignment. That pair of moves will open space on the 40-man roster for outfielders Harrison Bader and Hunter Renfroe, whose previously reported waiver claims have now been announced by the team.
Siani, 24, made his big league debut with the Reds last year and has briefly appeared this season as well, though he has just 25 MLB plate appearances under his belt overall. He’s 4-for-24 in that time (all singles). The 2018 fourth-round pick has never provided much offense in the minors, where he’s a .244/.338/.362 hitter (including .230/.337/.360 in Triple-A), but his glove and speed are his calling cards.
Siani once ranked as high as eighth among Reds prospects at Baseball America, but his bat hasn’t come around much as he’s progressed through the system. He still draws praise for 60-grade speed — which is made evident by last year’s 52 steals — and plus-plus defense in center field, where he has both ample range and a strong throwing arm. Siani has also walked in 11.4% of his minor league plate appearances, so while his hit tool and power are lacking, he can still post respectable OBP marks and provide value both with his glove (at all three outfield spots) and on the basepaths.
While Siani isn’t an impact bat, he has the makings of a glove-first fourth outfielder and has two minor league option seasons remaining beyond the current year. That could add up to some interest on the waiver wire. The Reds will place him on outright waivers within the next five days.
The 27-year-old Lopez was just selected to the big league roster two days ago but didn’t appear in a game before being removed. He’s seen big league time in each of the past two seasons with the Reds. Lopez has hit for a solid but empty .262 average in 179 career plate appearances, getting on base at a below-average .307 clip with just a .321 slugging percentage. He has big league experience at second base, third base and in the outfield corners. He’s fanned in just 14.6% of his career plate appearances but also walked at a well below-average 5% clip.
Like Siani, Lopez will be placed on waivers within the next five days. Unlike Siani, he’s been outrighted previously in his career, so if he clears waivers he’ll be able to reject a minor league assignment in favor of free agency.
Reds Designate Tony Santillan For Assignment
The Reds announced Tuesday that right-hander Tony Santillan has been designated for assignment. His spot on the 40-man roster will go to utilityman Alejo Lopez, who has had his contract selected from Triple-A Louisville. Outfielder Michael Siani was optioned to Louisville to clear active roster space.
A second-round pick back in 2015, the now-26-year-old Santillan ranked among the Reds’ top farmhands for several years before making his big league debut in 2021. He looked to be a potential mainstay in the bullpen after pitching 43 1/3 innings of 2.91 ERA ball with a hefty 29.5% strikeout rate. Santillan’s 11.1% walk rate was in clear need of improvement, but it was nonetheless an impressive debut campaign for a prospect whom the Reds viewed as a potentially notable part of their future.
As is so often the case, however, injuries have intervened and radically altered the equation. Ankle surgery, a stress fracture in his back and a knee strain have combined to limit the righty to just 23 big league innings since that debut. He’s posted a 5.09 ERA during that time, fanning just 19.3% of his opponents against an alarming 14.9% walk rate. Santillan has just 3 1/3 MLB frames under his belt this season and has otherwise spent the year in Louisville, where he’s been clobbered for a 9.26 ERA in 23 1/3 frames with nearly as many walks (22) as strikeouts (28).
Santillan still throws hard, averaging 96.1 mph on his heater over the past two seasons. He’s posted a solid 11.6% swinging-strike rate in his MLB career and clearly has had shown promise at times, but he’ll be out of minor league options next season and the Reds likely wouldn’t have gone through the entire offseason dedicating a 40-man spot to him anyhow. They’ll have no choice but to place Santillan on waivers now, and any team that claims him can keep him in the minors for the remainder of the year. He’d have to break camp on that team’s Opening Day roster next year or else again be designated for assignment, however.
As for the 27-year-old Lopez, he’ll join the Reds for a third straight season. He’s hit for a solid but empty .262 average in 179 career plate appearances, getting on base at a below-average .307 clip with just a .321 slugging percentage. He has big league experience at second base, third base and in the outfield corners. He’ll give the Reds a contact-oriented bench bat who’s fanned in just 14.6% of his career plate appearances but also walked at a well below-average 5% clip.
