Michael Siani

Dodgers Claim Michael Siani

By Darragh McDonald | December 12, 2025 at 1:45pm CDT

The Dodgers announced that they have claimed outfielder Michael Siani off waivers from the Braves. Atlanta designated him for assignment when they signed Mike Yastrzemski earlier this week. The Dodgers had a couple of 40-man roster vacancies. This move technically brings them to 39 but Edwin Díaz will take the final spot once his signing becomes official.

Siani, 26, is a glove-first depth outfielder. He has appeared in the past four major league seasons, spending time with the Reds and Cardinals. He was sent to the plate 383 times in that span. His 6.3% walk rate and 27.9% strikeout rate thus far in his career are both subpar figures. His .221/.277/.270 batting line is well below average. His minor league numbers aren’t much better. He has a .217/.329/.337 line on the farm over the past three years.

But he has been able to provide value elsewhere. He has stolen 21 bases in 26 attempts. He has logged 1,014 innings on the grass, playing all three spots, but mostly in center. He has been credited with 17 Outs Above Average in that time and seven Defensive Runs Saved.

Siani still has an option, meaning he can be send to Triple-A without being exposed to waivers. Regardless, the Cards put him on the wire at the end of the 2025 season. Atlanta scooped him up but he lasted barely a month on their roster.

The Dodgers have some fluidity in their outfield group. On paper, they have Teoscar Hernández and Andy Pages in two spots. There have been some trade rumblings around Hernández but general manager Brandon Gomes has pushed back on those. Pages had a good regular season but struggled in the playoffs and lost playing time. Tommy Edman could be involved but he’s recovering from ankle surgery right now and might be needed at second base. Hyeseong Kim is another multi-positional guy who could get some outfield time. Alex Call is in the mix.

Siani jumps into a depth group that also consists of Ryan Ward and Esteury Ruiz, all three of whom have options. Siani could be sent to Triple-A with those two but he could also carve out a bench role as a defensive specialist and pinch runner. He has less than two years of service time, meaning he hasn’t yet qualified for arbitration and can theoretically be retained for several years if the Dodgers find him useful.

Braves Sign Mike Yastrzemski

By Charlie Wright | December 10, 2025 at 7:16pm CDT

The Braves announced a two-year, $23MM contract with outfielder Mike Yastrzemski. He’ll make $9MM in 2016 and $10MM in 2027 and is guaranteed a $4MM buyout on a 2028 club option valued at $7MM. Yastrzemski is represented by Jack Toffey Sports Management. Atlanta designated outfielder Michael Siani for assignment in a corresponding move.

Atlanta hadn’t waded too far into the free agent market outside of re-signing closer Raisel Iglesias. The club now improves its outfield/DH mix by bringing in Yastrzemski. The lefty-swinging veteran finished last season with the Royals after getting dealt by the Giants at the trade deadline. After spending his first six seasons in San Francisco, Yastrzemski will now be on his third team in the calendar year.

Before the move, the Braves were looking at a pair of speed-first options in holdover Eli White and waiver claim Siani as their bench outfielders behind the trio of Ronald Acuna Jr., Michael Harris II, and Jurickson Profar. Yastrzemski gives them a more viable offensive contributor as the fourth outfielder. Braves president of baseball operations Alex Anthopoulos recently mentioned he preferred to leave the DH spot open and split the duties between multiple players. Yastrzemski figures to factor into that equation against right-handed pitching, grabbing left field reps with Profar moving to DH.

Yastrzemski was having one of his weakest offensive campaigns with the Giants prior to getting traded. He had managed just eight home runs and a career-low .355 SLG across 97 games. The move to Kansas City flipped his season, as he quickly emerged as a crucial top-of-the-order contributor. Yastrzemski slugged nine home runs in 50 games with the Royals, while walking more than he struck out. He capped off his season with a two-homer game against the Athletics.

The 35-year-old Yastrzemski didn’t reach the big leagues until age 28. He immediately made an impact in the power department, swatting 21 home runs in 411 plate appearances as a rookie. Yastrzemski earned near-regular playing time over the next five seasons, providing solid production against righties while typically sitting against lefties. He tended to strike out at an above-average rate, but still finished with a wRC+ of at least 106 in all but one season with the Giants.

Yastrzemski has spent the majority of his time in right field, though he has experience at all three outfield spots. He made six starts in left field, five starts in center field, and 29 starts in right field during his brief stint with the Royals. Yastrzemski graded out as a neutral fielder by Outs Above Average. His range received poor marks, but he offered value with his arm, per Statcast.

Kansas City was reportedly interested in a Yastrzemski reunion. Given his strong two months for the team, it made sense the Royals would look to bring him back. The club is currently short on proven outfielders, with Jac Caglianone, Kyle Isbel, and John Rave penciled in as starters. Considering that the trio is entirely left-handed, targeting a righty bat might be a better fit for Kansas City.

Robert Murray of FanSided first reported the Braves were nearing a deal with Yastrzemski. Jon Heyman of The New York Post first had the two-year, $23MM guarantee and the option.

Braves Claim Michael Siani From Cardinals

By Anthony Franco | November 7, 2025 at 3:05pm CDT

November 7: Thompson will actually not become a minor league free agent, per Derrick Goold of the St. Louis Post-Dispatch. He will stay in the Cards’ organization as part of the Triple-A Memphis roster. This appears to be because he spent the entire 2025 season on the major league injured list. Therefore, it doesn’t count as a minor league season and he doesn’t qualify for seven-year minor league free agency.

November 6: The Braves claimed outfielder Michael Siani off waivers from the Cardinals, relays Jeff Jones of The Belleville News-Democrat. St. Louis also outrighted left-handed pitchers Anthony Veneziano and Zack Thompson while selecting Bryan Torres onto the 40-man roster.

Siani, 26, is a glove-first center fielder. He has played in parts of four big league seasons but only got significant action in 2024. The lefty batter turned in a .228/.285/.285 slash with two homers and 20 steals over 124 games that year. Siani made just 19 big league appearances this past season. He spent the bulk of the season at Triple-A Memphis, where he slumped to a .209/.307/.329 batting line across 430 trips to the plate. Siani stole 28 bases and plays excellent outfield defense, but the bat is a significant question. He has one minor league option remanning.

Torres, 28, gets a 40-man roster spot after a decade in the professional ranks. He’s a 5’7″ utility player who moved between second base and the corner outfield spots. The lefty-hitting Torres had a breakout season with Memphis, batting .328/.441/.464 while walking more often than he struck out. He would have become a seven-year minor league free agent tonight if the Cardinals hadn’t put him on the 40-man roster.

Veneziano and Thompson will each become minor league free agents after going unclaimed on waivers. The 28-year-old Veneziano was a late-season waiver claim from Miami who pitched four innings of two-run ball for the Cards. He owns a 3.98 ERA over 40 2/3 career frames. Thompson, 28, was a first-round pick out of the University of Kentucky back in 2019. He missed the entire 2025 season with a torn lat.

IL Activations: Walker, Sanchez

By Mark Polishuk | June 14, 2025 at 5:20pm CDT

Here’s the rundown of some prominent names returning from the injured list today…

  • The Cardinals activated Jordan Walker from the 10-day IL, with fellow outfielder Michael Siani optioned to Triple-A in the corresponding move.  Walker returns to action after a little over two weeks on the IL, as the former top prospect was bothered by inflammation in his left wrist.  Operating as the Cards’ everyday right fielder, Walker has hit only .215/.273/.310 in 172 plate appearances this season, though his bat had been starting to heat up in the few games just prior to his injury.
  • The Orioles activated catcher Gary Sanchez from the 10-day IL, and optioned catcher Maverick Handley to Triple-A Norfolk.  Like Walker, Sanchez was also sidelined with wrist inflammation, though his issue was more severe since Sanchez hasn’t played in a big league game since April 27.  Sanchez will now resume his role as Adley Rutschman’s backup and hope that his IL stint essentially resets his season, as Sanchez had only three hits in his first 35 plate appearances in a Baltimore uniform.  The O’s signed Sanchez to a one-year, $8.5MM free agent deal back in December.

Cardinals Designate Ryan Vilade For Assignment, Select Andre Granillo

By Darragh McDonald | June 12, 2025 at 2:10pm CDT

The Cardinals announced that they have selected right-hander Andre Granillo to their roster and also recalled outfielder Michael Siani. In corresponding moves, they have optioned righty Chris Roycroft and designated outfielder Ryan Vilade for assignment.

Granillo, 25, was selected by the Cardinals in the 14th round of the 2021 draft. Exclusively a reliever, he has climbed the minor league ladder while posting good strikeout numbers and also giving out a high number of walks. He has 233 1/3 minor league innings under his belt to this point, having allowed 3.74 earned runs per nine innings. He has punched out 32.2% of batters faced in that time while also giving out free passes at a 12.7% clip.

It seems he has taken a big step forward in terms of his control this year. He has thrown 29 2/3 innings over 18 appearances with a 1.82 ERA. He has only walked 6.9% of batters faced while still getting punchies at a huge rate of 39.7%. In May of last year, FanGraphs ranked Granillo as the #21 prospect in the system. That report gave the highest praise for his slider, though it also mentioned his changeup and his mid-90s fastball.

With Granillo seemingly taking a big step forward at Triple-A, the Cards will give him a chance to face major league hitters. But that required a 40-man spot, so Vilade will get bumped off. Vilade, 26, signed a minor league deal with the Cards in the offseason. He put up a strong .280/.375/.476 line in 48 Triple-A games and was added to the roster a couple of weeks ago when Jordan Walker landed on the IL.

Unfortunately, Vilade hasn’t been able to do much in his limited big league playing time. He has been sent to the plate 15 times and struck out in five of those trips. He drew two walks but recorded just one hit, a single. He now has a .141/.200/.188 slash in his 71 big league plate appearances for his career.

He will now head into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Cards technically could take five days to explore trade interest. Vilade’s major league numbers aren’t good but in a tiny sample. Dating back to the start of 2024, he has a .279/.355/.457 slash and 114 wRC+ in 156 Triple-A contests. He also stole 25 bases in that time while playing the three non-shortstop infield positions and all three outfield slots. Since he still has an option year, perhaps he could appeal to a club looking for extra position player depth.

Cardinals Set Opening Day Roster, Plan To Use Six-Man Rotation In Mid-April

By Mark Polishuk | March 23, 2025 at 9:59pm CDT

Reports last week suggested that the Cardinals were thinking about utilizing a six-man rotation as a way of finding innings for both the veterans on the staff and for the younger arms the Cards are prioritizing in this semi-rebuild year for the franchise.  Manager Oliver Marmol confirmed to reporters (including The Athletic’s Katie Woo) today that the Cardinals will indeed use six starters during a busy stretch of the schedule that will see St. Louis play 26 games over 27 days from April 11 through May 7.

There is a bit of surprise in which starters will be involved in the expanded rotation, as the Cards optioned Michael McGreevy to Triple-A Memphis today.  McGreevy is one of the Cardinals’ top pitching prospects, and after impressing in his first 23 MLB innings last season, seemed poised to break camp with the team after posting a 1.08 ERA over 16 2/3 spring innings.

However, Matthew Liberatore also turned heads in camp, with a 1.62 across his own 16 2/3 frames of work.  As a result, Liberatore was named as one of the initial starting five (along with Sonny Gray, Miles Mikolas, Erick Fedde, and Andre Pallante), with Steven Matz slated to work as a long man before becoming the sixth starter.

Obviously, a single injury could change these plans considerably, and some other health issues in camp also perhaps factored in the Cardinals’ plans.  Zack Thompson and Drew Rom are both dealing with injuries, so McGreevy became needed as a Triple-A depth arm given the lack of other ready options.  Given how rare it is for a pitching staff to get through a season in one piece, it might not be long before McGreevy gets another opportunity in the Show.

The “you can never have too much pitching” mantra looms large in what is technically a surplus situation for the Cardinals pitching staff.  Yet the number of arms available also relates to a strangely quiet offseason, as the Cards ended up retaining most of their veteran talent despite their stated goal last fall to view 2025 as something of a re-development year.  The team’s inability to trade Nolan Arenado garnered the most headlines, yet on the pitching end, St. Louis also opted to keep Fedde, who has only one year remaining on his contract.  Gray had no interest in waiving his no-trade clause to go elsewhere, and trading Mikolas or Matz (also free agents next winter) could’ve probably required the Cards to eat some money since both pitchers are coming off down years.

Mikolas or Matz could be more plausibly moved closer to the deadline, perhaps in salary-dump fashion once some of their salaries are already doled out over the first half.  Fedde might be one of the most sought-after rental pitchers at the deadline if he matches his 2024 form, though naturally the Cardinals are hoping they can return to contention this year, rather than look to sell at the deadline.

Marmol also announced the rest of the Cardinals’ roster for Opening Day, including the news that Victor Scott II won the team’s center field competition.  Scott was battling with Michael Siani for the job, yet Scott outhit not only Siani (who struggled badly) but also just about the rest of the team by posting a 1.225 OPS over 49 plate appearances.  Scott may not play every single day since Lars Nootbaar also figures to get some time in center as the Cardinals juggle around their lineup, but Scott has put himself in position to get the lion’s share of playing time up the middle.

Arenado, Willson Contreras, and Masyn Winn will be the only true lineup regulars for St. Louis, and Brendan Donovan is also expected to play every day but at multiple positions.  Moving Arenado would’ve helped open up third base and a lineup position to get more players onto the field, yet Marmol said he is confident of the team’s plans to rotate players around without necessarily adhering to strict platoons.

“I’m going to do my absolute best to get everybody the necessary amount of at-bats for us to know what we have at the end of the year….We’ll see what this looks like in 30 days, 60 days, 90 days.  But we’ll have a [lineup] rotation that while we’re all healthy, still gets guys at-bats,” Marmol said.

Infielder Jose Fermin won’t be part of this mix in the early going, as Fermin was optioned to Triple-A today.  Woo notes that Fermin was told earlier this week that he would be part of the Opening Day roster, yet the Cardinals’ plan apparently changed in the last few days.  Without Fermin, the Cards don’t have a proper backup shortstop, yet the versatile Donovan will handle that role if Winn is given a breather.

Poll: The Cardinals’ Center Field Battle

By Nick Deeds | March 21, 2025 at 7:14pm CDT

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 59.73% (2,106 votes)
Lars Nootbaar 32.33% (1,140 votes)
Michael Siani 7.94% (280 votes)

Cardinals To Activate Steven Matz From 60-Day IL Tomorrow

By Nick Deeds | August 31, 2024 at 8:28pm CDT

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

By Nick Deeds | August 18, 2024 at 10:07am CDT

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

By Nick Deeds | August 4, 2024 at 2:14pm CDT

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.
