Cardinals Promote Brycen Mautz For Debut
10:15am: The promotion is now official. St. Louis optioned right-hander Matt Svanson to Triple-A to clear a spot for Mautz.
9:45am: Cardinals left-hander Brycen Mautz will be called up for his MLB debut on Sunday, relays Derrick Goold of the St. Louis Post-Dispatch. He’ll slide into the rotation with St. Louis coming off a doubleheader on Saturday.
It’ll be the second straight day with a big-league debut for the Cardinals, who promoted infielder/outfielder Bryan Torres on Friday. The longtime minor leaguer didn’t get into the first game against the Reds, but started both matchups of Saturday’s twin bill. Torres recorded three hits across the two games.
Mautz has delivered a sub-3.00 ERA across nine starts at Triple-A this season. He’s striking out more than a batter per inning, but his 13.5% walk rate is a career-worst mark. The 24-year-old is not among the upper tier of prospects in the St. Louis system, but he’s generally among the top 20 in the organization. FanGraphs‘ James Fegan ranked Mautz at No. 17 heading into the season, while MLB Pipeline had him at 20th.
The Cardinals selected Mautz in the second round of the 2022 draft out of the University of San Diego. The lefty posted decent results in his first pro season, recording a sub-4.00 ERA at Single-A. He took a step back in High-A the following year, with a 5.18 ERA to go with a 4.86 FIP. Mautz came through with a breakout season in 2025. He cruised to a 2.98 ERA with a career-best 28.6% strikeout rate in 25 starts at Double-A. Mautz was named the organization’s minor league pitcher of the year last season.
This could be a brief stint for Mautz, as the Cardinals don’t have a clear hole in the rotation. The group has remained healthy and generally provided decent results. Veterans Dustin May, Matthew Liberatore, and Andre Pallante haven’t excelled on a per-inning basis, but they’re offering length each time they take the ball. Michael McGreevy is off to a strong start. Kyle Leahy‘s transition to the rotation has gone reasonably well.

Cardinals Recall Bryan Torres For MLB Debut
May 22: These moves have now been formally announced by the club. Church was diagnosed with a left shoulder strain. A timetable for his return is not yet clear.
May 21: The Cardinals will promote second baseman/outfielder Bryan Torres for their weekend series in Cincinnati, reports former big leaguer Carlos Baerga. Jeff Jones of The Belleville News-Democrat reports that outfielder Nathan Church will land on the 10-day injured list in a corresponding move. Church was scratched from this afternoon’s lineup with an undisclosed issue and will miss at least the next week and a half.
St. Louis added Torres to their 40-man roster in November, so they won’t need any further transactions. The 28-year-old would otherwise have qualified for minor league free agency. Torres was coming off an excellent .308/.441/.464 season with Triple-A Memphis.
A native of Puerto Rico, Torres joined the professional ranks more than a decade ago. He signed with the Brewers as an undrafted free agent in 2015. Torres never made it out of rookie ball in the Milwaukee system. He had a brief stop in the Giants organization and was playing in the independent ranks as recently as 2023. The Cardinals evidently liked what they saw, as they added Torres on a minor league deal going into the ’24 season. He spent that year in Double-A and climbed to Triple-A a season ago.
Baseball America ranked Torres the #27 prospect in the St. Louis system over the offseason. They credit him with an above-average hit tool and average speed. Torres has minimal power but offers a bit of defensive flexibility and an OBP-oriented skillset off the bench. He’s out to an even better start in Memphis this year, running a .336/.454/.477 slash with more walks than strikeouts in 166 trips. He very rarely chases off the plate and makes a lot of contact, and he’s 10-12 in stolen base tries.
Torres is nearing his 29th birthday, so he’s not a traditional prospect. He’s in the top five among International League hitters in on-base percentage and doesn’t have much more to show versus minor league pitching. He can replace Church as the left-handed side of a left field platoon with José Fermín and Thomas Saggese for the time being.
2026-27 Club Options: NL Central
In recent weeks, MLBTR has looked forward to next winter’s option classes. We’ll move now to the NL Central, where the Cubs have a number of low-cost options to weigh.
Previous: AL East, AL Central, AL West, NL East
Chicago Cubs
- Matthew Boyd, LHP: $15MM mutual option ($2MM buyout)
Mutual options are essentially never exercised, so Boyd will be paid the $2MM buyout and return to free agency next winter. That’ll conclude a two-year, $29MM free agent deal that worked out well. Boyd’s 3.21 ERA over 31 starts a year ago essentially paid for the contract on its own.
The second season isn’t going as planned. Boyd missed a couple weeks in April with a biceps strain and suffered a more significant meniscus injury in his left knee earlier this month. He underwent surgery that’ll keep him out into late June at the earliest. The Cubs probably aren’t keen on their end of the option.
- Hunter Harvey, RHP: $8MM mutual option ($1MM buyout)
Chicago added Harvey on a one-year, $6MM deal in December. The talented but oft-injured reliever only pitched four times before landing on the injured list with triceps inflammation. Further testing this month revealed a stress reaction that’ll keep him down for a while. This will be an easy pass for the team.
- Carson Kelly, C: $7.5MM mutual option ($1.5MM buyout)
Kelly has outperformed his two-year, $11.5MM deal signed in December 2024. Initially brought in as a veteran complement to Miguel Amaya, the 31-year-old Kelly has earned the majority of the playing time. He’s a .261/.344/.421 hitter with 19 homers over his season-plus in Chicago. He’s fourth among primary catchers this season with a .381 on-base percentage. Kelly has a strong case for another two-year contract at a better annual rate than the option price, so his camp should have an easy time passing.
- Colin Rea, RHP: $7.5MM club option ($1MM buyout)
Rea, a 35-year-old swingman, is in the second season of his second stint with the Cubs. He’s clearly a favorite of skipper Craig Counsell, who also managed him in Milwaukee in 2021 and ’23. Rea pitched pretty well last season, managing a sub-4.00 ERA while starting 27 of 32 games. The Cubs had a $6MM team option for 2026, but the sides agreed to a restructured extension that guaranteed Rea $6.5MM in exchange for the righty tacking on a similarly priced club option for 2027.
Injuries again quickly pushed Rea from long relief into a back-end rotation spot. He hasn’t performed as well as he did last season, allowing nearly five earned per nine across 47 frames. Rea had consecutive quality starts against the Phillies in mid-April but has surrendered a 7.04 ERA over his past five times out.
Rea’s strikeout, walk and home run rates are all virtually identical to last season’s. There haven’t been any meaningful changes to his pitch mix or velocity. He’s essentially the same pitcher, with this year’s ERA spike mostly due to a higher average on balls in play. That’s always a risk for a pitcher like Rea who pounds the strike zone but doesn’t have overpowering stuff.
The Cubs will presumably look for a rotation upgrade or two in July that can push him back into a relief role. A buyout seems likelier than them picking up the option, though it wouldn’t be a surprise if they try to bring him back a slightly lower price given his flexibility in usage.
- Caleb Thielbar, LHP: $6MM mutual option ($500K buyout)
Chicago brought back Thilebar on a $4.5MM deal after he worked 58 innings of 2.64 ERA ball in 2025. The southpaw is making $4MM this year and will earn a $500K buyout at season’s end. He missed just under a month with a left hamstring strain and has been limited to 12 appearances. Thilebar has recorded 11 punchouts while allowing four runs (three earned) across 9 2/3 innings. The Cubs will probably pass on their end but could have interest in keeping Thielbar around for his age-40 season at slightly less money.
- Jacob Webb, RHP: $2.5MM club option (no buyout)
The Rangers surprisingly non-tendered Webb after he turned in 66 innings with an even 3.00 earned run average. Chicago signed him to a $1.5MM free agent deal that includes a $2.5MM team option for 2027. The righty has been a nice addition to Counsell’s middle relief corps, striking out a quarter of opponents with a 3.05 ERA over 20 2/3 innings. He’s getting swinging strikes and chases off the plate at career-best rates.
Webb has allowed right around three earned runs per nine in three straight seasons. His market has never really materialized, but a $2.5MM option is cheap enough that the Cubs would very likely bring him back if he keeps this pace all year.
The Cubs hold a $3.3MM club option on RHP Javier Assad. He’ll remain eligible for arbitration through at least 2028 even if the option is declined.
Cincinnati Reds
- Pierce Johnson, RHP: $8MM mutual option ($1.5MM buyout)
Cincinnati picked up Johnson on a one-year, $6.5MM deal after the Braves bought him out. The veteran righty has allowed eight runs over 19 1/3 innings with league average strikeout and walk numbers. His 9.3% swinging strike rate is a career low. Johnson is an MLB-caliber arm but more of a middle reliever than a setup man at age 35. An $8MM option price is too rich on the Reds’ end.
- Eugenio Suárez, DH/3B: $16MM mutual option
Cincinnati brought Suárez back on a one-year, $15MM deal late in the winter. It looked like a nice bargain pickup for a team that needed offense. Suárez’s age evidently tamped down long-term interest, but he hit 49 home runs a year ago. The return has started slowly, as he hit .231/.300/.363 through 100 plate appearances before sustaining a left oblique strain that sent him to the injured list. He began a rehab assignment with Triple-A Louisville yesterday.
The Reds will also pay a $3MM buyout to released infielder Jeimer Candelario.
Milwaukee Brewers
- Luis Rengifo, 3B: $10MM mutual option ($1.5MM buyout)
Milwaukee bought low on Rengifo with a $3.5MM deal in Spring Training. He’s making a $2MM salary and due a $1.5MM buyout on a $10MM mutual option. They haven’t gotten anything close to the desired bounce back. The switch-hitting utilityman carries a .199/.262/.257 line without a home run over 150 plate appearances. Third base feels like a priority for the Brewers at the deadline, at which point they could move on from Rengifo entirely.
- Gary Sánchez, C: Mutual option
The terms of Sánchez’s mutual option were never reported. He signed a $1.75MM guarantee to return to Milwaukee as a backup catcher/part-time DH. Although Sánchez is only hitting .198, he has walked 20 times and hit five home runs in 108 plate appearances. The Brewers will eventually want a look at prospect Jeferson Quero, but William Contreras will be an offseason trade candidate with free agency looming after 2027. They could look to keep Sánchez around as a cheap #2 catcher.
Milwaukee holds a $14.5MM club option on C William Contreras for his final season of arbitration. He’ll remain under team control if Milwaukee declines.
Pittsburgh Pirates
- Marcell Ozuna, DH: $16MM mutual option ($1.5MM buyout)
Pittsburgh added Ozuna late in the offseason on a $12MM deal. It didn’t make much sense at the time since it locked all of Ryan O’Hearn, Brandon Lowe and Spencer Horwitz into defensive spots without a fallback at designated hitter. Ozuna was also coming off a mediocre second half and playing in one of the toughest home parks for right-handed power.
Ozuna had an atrocious April. He’s at least drawing a lot of walks in May, but his season .179/.275/.305 line isn’t cutting it. It goes without saying that the Pirates aren’t exercising a $16MM option. The bigger question is whether they’ll keep Ozuna on the roster all year.
St. Louis Cardinals
- Dustin May, RHP: $20MM mutual option ($500K buyout)
May commanded a surprisingly strong $12.5MM guarantee despite coming off a 4.96 ERA season between the Dodgers and Red Sox. He’s making a $12MM salary and will collect a $500K buyout on the $20MM mutual option at season’s end. May has stayed healthy and taken all nine turns through the rotation, but he’ll take a 4.81 ERA into today’s start against the Pirates. His strikeout and whiff rates are well below average despite his 97 mph fastball. While May’s power stuff and early-career success have continued to intrigue teams, the recent performance has been that of a fifth starter. The Cardinals aren’t signing up for a $20MM option.
- Ryne Stanek, RHP: $6MM club option (no buyout)
St. Louis added the hard-throwing Stanek on a $3.5MM deal in January. They wanted an experienced leverage arm who could compete for the closing role and potentially be a midseason trade asset. Riley O’Brien seized the ninth inning, leaving Stanek alongside JoJo Romero and George Soriano in the setup group.
Stanek continues to sit around 98 mph and generate above-average strikeout and whiff rates. His already problematic control has pushed even further, though, and he’s walking nearly 18% of opposing hitters. It’s the third-highest mark among pitchers with at least 20 innings. The free passes have resulted in a 6.30 ERA over 23 appearances. Teams are inclined to bet on pitchers with this kind of stuff, but Stanek will need a better second half to convince the Cardinals (or a potential midseason trade partner) to bring him back for $6MM.
- Ramón Urías, 3B: $4MM mutual option ($500K buyout)
St. Louis added Urías on a $2MM free agent deal during Spring Training. He’s making $1.5MM in salary and will be paid a $500K buyout. Urías limped to a .158/.279/.316 start over 25 games before landing on the injured list with tennis elbow.
Cardinals Outright Jared Shuster
For the second time this season, the Cardinals outrighted Jared Shuster to Triple-A Memphis (relayed by Jeff Jones of The Belleville News-Democrat). The left-hander has the right to decline the assignment in favor of free agency, though he previously forewent that option in the middle of April.
Shuster has made four MLB appearances with the Cardinals in two stints on the roster. He has worked multiple innings in three of those and allowed two earned runs. Shuster has tallied 7 2/3 frames with just six hits and two unintentional walks. He has only recorded two strikeouts, though, missing bats on 3.5% of his pitches.
A first-round pick by Atlanta in 2020, Shuster is a pitchability lefty whose arsenal was headlined by a plus changeup. The Braves hoped he’d move quickly and slot at the back of a rotation, but the lack of swing-and-miss has kept him in a depth/swing role. Atlanta traded him to the White Sox after the 2023 season in the Aaron Bummer deal. Chicago lost him on waivers to the A’s last summer, and he signed with St. Louis after the A’s released him in December.
Shuster carries a 5.12 earned run average with a 15% strikeout rate across 149 1/3 MLB innings. He has a 5.45 ERA over parts of five Triple-A seasons, including this year’s 9 2/3 frames of nine-run ball in Memphis. Shuster is out of options and needs to clear waivers each time a team wants to assign him to the minors.
Cardinals Designate Jared Shuster For Assignment
The Cardinals announced that left-hander Jared Shuster has been designated for assignment. The move opens up roster space for right-hander Matt Pushard, who is back from the 15-day injured list after recovering from patellar tendinitis in his right knee.
It was a little over a month ago that Shuster was first DFA’ed by the Cards, and the southpaw was outrighted to Triple-A after clearing waivers. Shuster chose to accept that assignment rather than opt for free agency, so he’ll face that decision again if he again clears waivers this time around.
Because Shuster is out of minor league options, he’ll have to be designated for assignment whenever the Cardinals or another team wants to send him down to Triple-A or create space on a 26-man roster. Given this state of perpetual roster limbo, Shuster might prefer to somewhat reduce the tumult by just staying with St. Louis, so he’d at least have the familiarity of remaining in the same organization. That said, if Shuster feels his big league opportunities will be limited with the Cards, he could choose to test the market this time around.
It also isn’t out of the question that Shuster is claimed off waivers, given how teams are perpetually in need of left-handed pitching depth. The Athletics claimed Shuster away from the White Sox last August, when Shuster was DFA’ed for the first time in his career. Shuster has a 2.35 ERA over the small sample of 7 2/3 innings for St. Louis this season, plus an 8.38 ERA over 9 2/3 frames for Triple-A Memphis — ironically, his peripheral numbers in the Show are unimpressive while his metrics in Triple-A have been pretty solid, though both represent small sample sizes.
Selected 25th overall by Atlanta in the 2020 draft, Shuster has only a 5.12 ERA, 15% strikeout rate, and 10.1% walk rate to show for 149 1/3 MLB innings with the Braves, White Sox, and Cardinals. Shuster’s brief time in the Athletics’ organization ended without any big league action, and he signed with St. Louis on a minor league deal during the offseason.
What Should The Cardinals Do With Riley O’Brien?
It’s been a weird year for closers. Edwin Díaz, Josh Hader, Ryan Helsley, Emilio Pagán, Carlos Estévez and others are on the injured list. Jeff Hoffman lost his job with the Blue Jays. Pete Fairbanks, just reinstated from the IL, has an earned run average of 10.00. Devin Williams and Andrés Muñoz have ERAs over 5.00. Bryan Abreu, filling in for Hader, has an ERA over 8.00. The Cardinals, meanwhile, are getting great results from a guy who hardly pitched in the majors before his 30th birthday.
St. Louis acquired Riley O’Brien in a very small trade in November of 2023. At the time, O’Brien didn’t even have a 40-man roster spot with the Mariners. All 29 other clubs had passed on claiming him when Seattle placed him on outright waivers in the summer of 2022. He was about to become a minor league free agent, but the Cards saw enough in O’Brien to send cash to Seattle to acquire him and place him on their 40-man roster so he couldn’t hit the open market.
The track record at that time wasn’t much to go on. An eighth-round pick of the Rays in 2017, O’Brien began his career as a starting pitcher. He was flipped to the Reds in August of 2020 for left-hander Cody Reed. Cincinnati added O’Brien to the 40-man roster that November to keep him out of the Rule 5 draft. Things didn’t work out with the Reds. O’Brien made a brief major league debut in 2021 but posted a 4.55 ERA in Triple-A. He was designated for assignment early in 2022 and shipped to the Mariners for cash or a player to be named later.
O’Brien was moved to a relief role in 2022, a switch that didn’t immediately bear fruit. He finished the year with a 7.03 ERA in 39 2/3 Triple-A innings. He seemed to turn a corner in 2023 when he threw 55 Triple-A innings with a 2.29 ERA in the hitter-friendly Pacific Coast League. O’Brien struck out 37.7% of batters faced and induced grounders on 57.1% of balls in play. His 13.6% walk rate showed that he was still working on his control, but the Cards were intrigued enough to make that small trade and dedicate a 40-man spot to him.
That didn’t pay off right away. O’Brien suffered a flexor strain early in 2024 and missed most of the season. He was only able to make eight big league appearances and 14 more in Triple-A. He went into 2025 with only 10 1/3 major league innings under his belt. He turned 30 in February of that year, just before the season started.
O’Brien was finally able to break out in the big leagues last year, as he gave the Cards 48 innings with a 2.06 ERA. He wasn’t really as good as that ERA would suggest, however. His 11.1% walk rate was quite high and his 22.6% strikeout rate only average. His 54.1% ground ball rate was good but he got a lot of help from a .252 batting average on balls in play and 82.8% strand rate. His 3.61 FIP and 3.82 SIERA suggested he was good but not quite as dominant as the ERA made it seem.
The Cardinals sent him to the minors a few times last year and burned his final option year. That situation could push a pitcher off the roster, but that’s not going to happen anytime soon with O’Brien. He has taken over the closer’s role in St. Louis, with a 2.70 ERA and 12 saves in 20 innings so far this year. Though that ERA is higher than last year’s, the numbers under the hood look far better. His 29.5% strikeout rate, 2.6% walk rate and 62% ground ball rate are all huge improvements. His .320 BABIP this year actually skews a bit to the unlucky side. His 2.06 FIP and 1.67 SIERA think he actually deserves far better than his ERA.
The results are backed by a strong arsenal. O’Brien is averaging 98.4 miles per hour with his sinker, a pitch he is throwing 59.2% of the time. This year’s most-used secondary pitch is a sweeper that comes in around 83.8 mph, though he’s also using a 91.5 mph slider, giving hitters two different breaking pitches to watch out for. There’s also a changeup nominally in the mix, though that has made up less than 1% of his offerings this year.
O’Brien’s success is a big reason why the Cardinals are playing a bit above their heads right now. They have a 24-18 record despite an essentially even run differential. They have scored 194 runs and allowed 193. The +1 run differential gives them an expected win-loss of 21-21, but they have gone 8-3 in one-run games and 5-1 in extra innings. In short, they’ve played like a .500 team on the whole but have eked out three extra wins in close contests. O’Brien locking down 12 saves and earning three wins has surely played a role in tipping those scales.
It puts the Cards in an interesting spot this summer. They had planned for this season to be an evaluation year. They traded away Sonny Gray, Willson Contreras, Nolan Arenado and Brendan Donovan in rebuilding moves. The plan was to spend 2026 letting less-established guys accumulate lots of playing time, so the club could figure out who is a building block and who has trade value.
Perhaps the Cardinals will fall back in the standings and make things easier for the team brass. If not, it could lead to some tough decisions. The front office probably doesn’t want to buy at the deadline since that would require subtracting from the farm system, at a time when they are trying to build it. In fact, they probably want to do more selling, with guys like Lars Nootbaar, JoJo Romero, Dustin May, Nolan Gorman and Alec Burleson being some logical trade candidates.
O’Brien will be a very interesting player to track as well. On the one hand, he is not close to free agency. He came into this year with one year and 129 days of service time. He’s under club control for four more seasons after this one. He could qualify for arbitration this offseason as a Super Two guy, but even he does, four arb years for what looks like a potential high-end reliever is a great thing to have. There’s a case for keeping him around.
On the other hand, reliever performance tends to be quite erratic. O’Brien is 31 years old and doesn’t have a long track record of big league success. He walked 11.6% of batters faced in his minor league career. He had a 13.1% walk rate in the majors coming into this season. He’s now walking just 2.6% of opponents this year. Did he suddenly go from poor control to elite, or is this going to regress?
There’s also the ever-present injury concerns with a pitcher, especially one who throws almost 100 mph. Most high-velocity pitchers deal with arm issues these days and O’Brien had that aforementioned flexor strain in 2024.
There are many moving pieces here, making O’Brien an interesting player to watch in the coming months. As mentioned up top, lots of clubs have gotten poor results from their closers. Relievers are always in demand at the deadline and that need will perhaps be even greater this year. There’s an argument for the Cards to cash in while O’Brien is putting up good numbers. When they plan to truly contend in a few years, he’ll be pushing into his mid-3os and who knows what his status will be at that point?
Between now and the August 3 deadline, there are many ways it could tip. O’Brien could keep locking down games but he could also see his control slip or he could perhaps get hurt. The team could keep winning games and hang in the race or they could slip back. Trade talks won’t earnestly ramp up for a while but the Cardinals will have some interesting phone calls this summer.

Cubs Claim Luis Peralta From Cardinals
The Cubs have claimed left-hander Luis Peralta off the Cardinals’ waiver wire, according to Taylor McGregor of the Marquee Sports Network. St. Louis designated Peralta for assignment on Friday. Peralta has been optioned to Triple-A Iowa, and a 40-man roster move wasn’t required since the Cubs only had 39 players on their 40-man.
It’s the second time in less than a week that Peralta has changed teams via the waiver wire. He was designated for assignment by the Rockies on April 21 and was claimed by the Cardinals on Monday, only for the Cards to return Peralta to DFA limbo when a 40-man roster spot was needed to select Jared Shuster‘s contract from Triple-A.
Peralta’s tenure in St. Louis ends without even a minor league appearance, so his 2026 numbers remain just the ugly 17.18 ERA he posted over six appearances and 7 1/3 innings for the Rockies’ Triple-A affiliate. Peralta has a 10.26 ERA over 43 career Triple-A innings, with the caveat that he has worked only in the hitter-friendly Pacific Coast League.
The southpaw’s time in the majors hasn’t been much better. Peralta had an impressive 0.73 ERA across 12 1/3 innings after he made his MLB debut with Colorado in 2024, but he came back to earth with a 9.47 ERA in 19 frames of work in 2025. Peralta allowed six homers in that 19-inning sample, with more walks (18) than strikeouts (16).
Control has been a persistent issue for Peralta throughout his career, and the problem worsened to the tune of 13 walks allowed over his 7 1/3 innings in Albuquerque this year. Despite his strong strikeout numbers, it will be hard for Peralta to stick even as minor league bullpen depth if he can’t get the ball over the plate.
Chicago becomes the latest team to see if it can solve Peralta’s control woes, and any kind of extra arms are helpful given how the Cubs have six relievers currently on the injured list. Left-handers Caleb Thielbar and Riley Martin are among that sextet, so Peralta can add some depth behind the bullpen’s current southpaw pairing of Hoby Milner and Ryan Rolison.
Lars Nootbaar To Begin Rehab Assignment Soon
The Cardinals have gotten out to a surprisingly good start, with a 19-13 record entering play today. That’s mostly due to their offense, which ranks sixth in the Majors with a 107 team wRC+. A key contributor to that offense is making progress on his rehab. Outfielder Lars Nootbaar is set to begin a rehab assignment the week of May 10, according to manager Oli Marmol (link via Jeff Jones of the Belleville News-Democrat).
Nootbaar has started 2026 on the injured list. He underwent surgery in October to address Haglund’s deformities in both of his heels, which may have kept the rebuilding Cardinals from seriously pursuing a trade. The club likely hoped Nootbaar would be healthy for the start of the year and make himself a trade candidate come July. He did not progress as hoped, though. Nootbaar did not appear in any Spring Training games and instead landed on the 60-day IL on March 25. Assuming a full 20-day rehab assignment, he could return in early June in the best-case scenario.
Nootbaar had a 114 wRC+ or better in every year from 2022-24. Although he missed significant time due to injuries, he was still good enough for 7.4 fWAR in that span. Unfortunately, Nootbaar took a step back in 2025. He reached a career high with 583 plate appearances, but the result was a line of .234/.325/.361 and a 96 wRC+, his first below-average mark in a full season. On defense, Nootbaar spent most of his time in left field and regressed to -4 Outs Above Average, showing diminished range but above-average arm strength. In the perfect world, St. Louis would see Nootbaar resume his regular role after two months on the IL and post above-average offense as he did from 2022-24.
In Nootbaar’s absence, the Cardinals’ outfield has been a mixed bag. The surprise breakout of Jordan Walker accounts for a lot of their production so far. After posting well-below-average numbers in 2024-25, Walker has a staggering 166 wRC+ and nine home runs through 134 plate appearances in 2026. He is also batting an unsustainable .394 on balls in play, so some regression is inevitable. Nathan Church and Victor Scott II occupy left and center field at present. Church has been below-average (91 wRC+), while Scott has been downright dreadful (30 wRC+). Both are young players with options remaining, though Scott is the more likely demotion when Nootbaar returns given his total lack of offense.

Cardinals Designate Luis Peralta For Assignment
The Cardinals designated lefty Luis Peralta for assignment Friday, the team announced. His 40-man roster spot goes to fellow southpaw Jared Shuster, whose contract has been selected from Triple-A Memphis. The Cards opened an active roster spot by optioning righty Hunter Dobbins to Triple-A following yesterday’s season debut.
St. Louis only claimed Peralta off waivers out of the Rockies organization three days ago. He’s yet to even pitch in a game in their system and will now be in limbo for up to a week as he awaits the outcome of this morning’s DFA. The Cardinals will have five days to either trade Peralta or place him back on outright waivers. Since outright waivers are a 48-hour process, it could take up to seven days for a resolution.
The 25-year-old Peralta has pitched in parts of two big league seasons, both with the Rockies. He’s logged 31 1/3 MLB frames and been charged with 21 earned runs (6.03 ERA) on 33 hits, 23 walks and four hit batters. He’s fanned 30 of his 150 opponents. Peralta is effectively a two-pitch reliever, working off a four-seamer that averages 94.7 mph and a curveball that sits 81.7 mph. He mixes in an extremely occasional mid-80s changeup; only two percent of his MLB pitches have been changeups.
Peralta had a huge 2024 season in the minors, logging a pristine 0.94 ERA with a 40.1% strikeout rate and 11.2% walk rate in 47 2/3 innings across three minor league levels. He’s been hit hard and missed time with a hip injury over the two subsequent seasons. If the Cardinals can succeed in passing him through waivers, he’ll have to head back to Triple-A Memphis, as he lacks the prior outright or three years of MLB service time needed to reject an outright assignment to the minors. He’s already been claimed once and has a pair of minor league options remaining, however, so it’s possible another club will scoop him up.
Shuster has already had one stint with the Cards this season. The 27-year-old pitched 3 2/3 innings and allowed two runs before being designated for assignment, clearing waivers and accepting an outright assignment to Memphis.
A former first-round pick by the Braves, Shuster has pitched in parts of four major league seasons without much success. He owns a lifetime 5.26 ERA in 145 1/3 innings and has posted strikeout and walk rates that are both worse than league average. He’s been tagged for nine earned runs in 9 2/3 Triple-A frames this season.
It could very well be another short stay on the roster for Shuster. The Cardinals needed a fresh arm in the bullpen after Dobbins was chased in the fifth inning yesterday. They needed five relievers to get through the rest of the game. All five threw at least 15 pitches. Ryne Stanek and JoJo Romero have both pitched on consecutive days and combined for 37 and 38 pitches, respectively. The Cards would probably prefer to stay away from either, if possible.
Cardinals Claim Luis Peralta
The Cardinals have claimed left-hander Luis Peralta off waivers from the Rockies, according to announcements from both clubs. Colorado designated him for assignment last week. The Cards had an open 40-man spot and have optioned Peralta to Triple-A Memphis, so no corresponding moves are necessary.
Peralta, 25, is the younger brother of Freddy Peralta. The younger sibling was a starter earlier in his career but got moved to a relief role when he was a minor leaguer with the Pirates. He showed tremendous promise in that role in 2024, the year he was traded to the Rockies in a one-for-one swap for Jalen Beeks.
Between the two clubs, he tossed 47 2/3 minor league innings that year, allowing only 0.94 earned runs per nine. He did give out walks at a high rate of 11.2% but his 40.1% strikeout rate was massive and his 48.8% ground ball rate above average as well. He also got to make his big league debut and put up a 0.73 ERA in 12 1/3 innings.
Things have been going downhill since then, however. He had a 9.47 ERA in the majors last year and a 9.09 ERA at the Triple-A level. For Albuquerque, his 28% strikeout rate was still pretty good but his 15.4% walk rate way too high. In the majors, things were even worse, as his ghastly 17.8% walk rate was higher than his 15.8% strikeout rate. He began 2026 back at Triple-A but but allowed 14 earned runs in 7 1/3 innings while walking 13 opponents.
His velocity is down a bit as well. His four-seamer averaged 95 miles per hour in 2024 but dropped about half a tick last year and is now down to 93.5 miles per hour so far in 2026. His curveball and changeup have had similar drops.
The Rockies eventually gave up. Perhaps that’s because the new front office is less enamored of Peralta but it’s hard to fault them when looking at Peralta’s recent numbers. For the Cards, despite a 14-13 record at the moment, they have long planned for 2026 to be an evaluation year. They are less focused on immediate contention and more worried about long-term development.
They’ve had an open roster spot since Jared Shuster was designated for assignment two weeks ago. They are using that today to grab Peralta. Obviously, Peralta’s stock is down at the moment, but the Cards will see if there’s a path to getting him back to that 2024 form. Peralta can be optioned for the remainder of this year and one additional season as well. If things click, he has less than a year of service time, meaning he could be affordably controlled for years into the future.
