Pirates Place Konnor Griffin On 10-Day IL, Activate Ryan O’Hearn
The Pirates are placing shortstop Konnor Griffin on the 10-day injured list, according to Colin Beazley of the Pittsburgh Post-Gazette. Per Jason Mackey of MLB.com, Griffin has a flexor tendon strain and he’s expected to miss only a short time. Ryan O’Hearn is being activated off the injured list in his place.

Tigers Activate Kerry Carpenter From 10-Day Injured List
The Tigers have activated Kerry Carpenter from the 10-day injured list, per Tony Paul of The Detroit News. He will bat fourth and serve as the DH today against the White Sox. Gage Workman has been optioned to Triple-A Toledo in a corresponding active roster move.
Carpenter has been on the shelf since May 10th with a left AC joint sprain. Recent reporting indicated that he and Gleyber Torres were set to begin rehab assignments. In Carpenter’s case, that ended up lasting just two games. He now returns to the Tigers having missed exactly three weeks.

Twins Place Bailey Ober On Injured List, Select Mike Paredes
The Twins are placing right-hander Bailey Ober on the 15-day injured list with elbow inflammation, according to Dan Hayes of The Athletic. They are also selecting the contract of Mike Paredes from Triple-A. He’ll be making his major league debut when he gets into a game. Meanwhile, Travis Adams has been recalled from Triple-A, while John Klein is being optioned in his place. The Twins’ 40-man roster is at 39 with Paredes’ selection, so no corresponding 40-man move is needed.

Brewers Activate Rob Zastryzny, Transfer Angel Zerpa To 60-Day IL
The Brewers have activated left-hander Rob Zastryzny off the 60-day injured list to rejoin their bullpen, according to Adam McCalvy of MLB.com. Righty Carlos Rodriguez is being optioned to Triple-A. Angel Zerpa has been shifted to the 60-day IL in Zastryzny’s place.
Zastryzny pitched for Team Canada in the World Baseball Classic but suffered a left shoulder strain in spring training with Milwaukee. He was placed on the 15-day injured list on March 25th and transferred to the 60-day IL in mid-April. That ruled out Zastryzny through the end of May, though he’s now healthy and returning for his third season with the Brewers.
Zastryzny’s had three extended injury absences since joining the Brewers for the 2024 season, so he’s only thrown 29 2/3 innings for them. His results in that sample have been solid. Zastryzny has a 2.12 ERA while allowing just a .580 OPS to opposing hitters since 2024. At the same time, Zastryzny’s fastball sits in the low 90s, and his 4.09 FIP since 2024 shows he benefitted from good luck (and good defense behind him).
That said, the Brewers only need Zastryzny to be a serviceable arm, not a premium back-end reliever. The club’s bullpen is in the Top 10 in the Majors by most metrics, including strikeout rate (24.3%), K-BB rate (13.9%), groundball rate (45.9%), and ERA (3.28). Among eight qualified Brewers relievers, only Trevor Megill and Jake Woodford have ERAs over 4.50. Megill has a a 2.88 expected ERA and strong peripherals, so he’s due for positive regression. Led by the nine-win Aaron Ashby, the other relievers have ranged from solid to excellent. Zastryzny is out of options, so he’ll need to re-establish himself quickly, as he can only be taken off the roster by a DFA.
Zerpa’s move to the 60-day IL is entirely expected. He underwent Tommy John surgery a few weeks ago and will therefore miss all of 2026 and a good chunk of 2027. Zerpa will likely repeat his $1.095MM salary in arbitration as a result. The left-hander had a 4.03 ERA in 118 1/3 innings with Kansas City from 2024-25, along with a staggering 60.5% groundball rate that was fifth-best among qualified relievers. With Zerpa’s current timeline, he’ll have the opportunity to provide a year and a half of serviceable relief before hitting free agency after 2028.
Rodriguez heads back to Triple-A having only made two appearances in his latest stint in the Majors. He was recalled on May 24th and threw two scoreless innings against the Dodgers that same day. Rodriguez’s next appearance on May 30th was less fortunate, as he allowed three earned runs in 3 1/3 innings against the Astros. He’s only 24 and has been optioned and recalled several times this year, so Rodriguez will certainly get more chances in the Brewers’ bullpen.

Orioles Outright Dietrich Enns
TODAY: Per Roch Kubatko, Enns has cleared waivers and accepted an outright assignment to Triple-A Norfolk.
May 26th: The Orioles announced that they have recalled left-hander Nick Raquet from Triple-A Norfolk, a move that was reported by Roch Kubatko of MASNsports.com earlier. In a corresponding move, the O’s designated fellow lefty Dietrich Enns for assignment.
Enns, now 35, had an intriguing comeback season in 2025. He had made his major league debut a few years prior but wound up pitching overseas from 2022 to 2024. He was back in North America last year and logged 46 1/3 innings between the Tigers and Orioles. He allowed 4.08 earned runs per nine. His 24.5% strikeout rate and 7.5% walk rate were both a bit better than average. He may have even had better results without a .338 batting average on balls in play, which is why his 3.54 SIERA was a bit lower than his ERA.
The O’s signed Enns for the 2026 season, a one-year deal with a $2.625MM guarantee and a club option for 2027. Here in 2026, a left foot infection put him on the IL for about a month, from early April to early May. Around that IL stint, he has given Baltimore 16 innings with a 3.94 ERA but with worse numbers under the hood. His 18.6% strikeout rate and 15.7% walk rate are both subpar figures. His BABIP and strand rate are now to the lucky side, so his 5.24 SIERA suggests he’s been worse than last year, even though he ERA is slightly better.
The Rays and Orioles went to 13 innings last night. Baltimore ultimately came out on top but it was a bit of a pyrrhic victory, as they had to use six relievers in the process. One of them was Enns, who was pitching for a second straight day. It’s likely that Baltimore’s decision to cut Enns came from a combination of the pitching staff being taxed, him being unavailable, and his uninspiring results this year. He is out of options and needed to be bumped off the 40-man entirely to open an active roster spot.
Enns now heads into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Orioles could take five days to explore trade interest. Given this year’s results and salary, they may not find much interest. If Enns were to clear waivers, he would likely stick around as non-roster depth. He has a previous career outright and would technically have the right to elect free agency in that scenario. But since he has less than five years of big league service time, he would have to walk away from the money he is still owed on his current deal.

Rays Place Craig Kimbrel On 15-Day IL, Announce Other Moves
The Rays have placed right-hander Craig Kimbrel on the 15-day injured list with a right wrist strain, per a team announcement. The move is retroactive to May 28th. The club is also recalling lefty Cam Booser and righty Trevor Martin from Triple-A. In addition, righty Andrew Wantz is being designated for assignment, removing him from the 40-man roster.
Kimbrel joined Tampa Bay on a major league deal last week. That came after he was designated for assignment by the Mets and elected free agency. Kimbrel only got into one game with his new club, striking out two hitters in a scoreless inning on May 26th. Now, he’ll be on the shelf through at least June 4th, continuing a frustrating age-38 season for the once-great closer.
Kimbrel had a 6.00 ERA in 15 innings with the Mets before joining the Rays. Although his 4.39 expected ERA was much better, that’s obviously still not a good mark and shows that Kimbrel is a shell of his old self even accounting for poor luck. Kimbrel is averaging 93.6 MPH on his four-seamer in 2026, continuing his decline from 2023, when the pitch averaged 95.8 MPH. Dating back to the start of 2025, Kimbrel has a 4.18 ERA in 28 innings, with opposing hitters putting up an .806 OPS against him.
At best, low-leverage relief is what the Rays can expect from Kimbrel when he gets back. Tampa’s starters rank third in the Majors with a 3.11 ERA, but their bullpen ranks 25th with a 4.74 mark. Bryan Baker and Kevin Kelly have both been excellent, especially Baker in the closer role. In contrast, Jesse Scholtens is underperforming his 4.99 expected ERA by two runs, and he’s now on the injured list himself. The other qualified relievers have a 4.67 ERA or higher. Lengthy track record aside, Kimbrel probably has a short leash when he returns from injury, as the Rays won’t risk worsening their bullpen long-term with only a slim lead over the Yankees in the AL East.
In the meantime, Booser and Martin are back in the Majors as fresh arms. Booser was optioned before Opening Day and hasn’t appeared in the Majors this season, though he has a sharp 1.80 ERA in 20 innings at Triple-A. That mark comes with a 6.3% walk rate, so the Rays might be counting on improved control from Booser in the big league bullpen, at least over his 13.3% walk rate last year with the White Sox. The same can be said of Martin, who’s allowed eight walks in 15 innings at Triple-A this year but has generally limited free passes in the minors.
Wantz loses his roster spot after a single game with the Rays. He allowed five earned runs on 54 pitches in 1 2/3 innings yesterday’s 14-3 loss to the Angels. Wantz was only selected the day before, though he was out of options and needed to be designated to be taken off the roster. Wantz has been outrighted before and can technically reject an outright assignment if he clears waivers. However, he’s only thrown three innings in the Majors since the start of 2024, so it’s possible Wantz remains in the organization and waits for a call-up to re-establish himself.

The Opener: Montgomery, Tatis, Miles
The Orioles won 6-5 against the Blue Jays yesterday on a stunning five-run ninth inning comeback. Taylor Ward made a small bit of history in the game, drawing his 51st walk of the season in the home half of the first. He’s the first in Orioles franchise history to walk 51 times in the first 58 games of the season. With a .404 on-base percentage, Ward continues to be an on-base machine this year.
1. Montgomery’s homer pace
White Sox shortstop Colson Montgomery hit career home run No. 35 in yesterday’s 7-1 victory over the Tigers. The contest was Montgomery’s 128th career game, making him the fastest in South Side history to reach 35 home runs. José Abreu was the previous record holder, hitting 35 home runs in 133 games in his 2014 rookie season. As for Montgomery, the second-year shortstop continues to show impressive power with a .252 isolated slugging percentage.
2. Tatis finally goes yard
After a 55-game homerless streak to start 2026, Fernando Tatis Jr. finally went yard with a 451-foot blast against Foster Griffin of the Nationals. Tatis has been mired in the worst offensive season of his career, with his drop in power being the most notable change. Tatis has improved on a dreadful April with a 119 wRC+ in May, so perhaps getting over the mental hurdle of hitting his first home run will help him return to the Tatis of old.
3. Miles to start for Blue Jays today
Per Arden Zwelling of Sportsnet, the Blue Jays will give Spencer Miles a traditional start today against the Orioles, in lieu of using an opener. Miles, a fourth-round draft pick by the Giants in 2022, is impressing with a 2.16 ERA in his first 15 big league appearances. Only one appearance, a three-inning, 38-pitch extended opener job on May 10th, counted as a start. Miles has averaged over four innings in three bulk relief appearances since then, so he should be good to go for 70-75 pitches today.

Nolan Arenado’s Arizona Bounce-Back
Nolan Arenado‘s no-trade clause was the most obvious obstacle for the Cardinals in their attempts to trade the third baseman during the last two offseasons, as Arenado (especially during the winter of 2024-25) had a very short list of acceptable landing spots. It didn’t help that Arenado was also owed a substantial amount of money, and St. Louis ended up eating $31MM of the $42MM remaining on the third baseman’s contract once Arenado finally approved a trade to the Diamondbacks last January.
The bigger-picture issue hovering over the situation, however, was simply the fact that Arenado looked like a player in decline. After a superb 2022 season with the Cards that saw Arenado finish third in NL MVP voting, Arenado dropped down to a modest 107 wRC+ in 2023, then a 102 wRC+ in 2024, and then an ugly 84 wRC+. It was just the third time in Arenado’s career that he had delivered below-average offense, with the other two instances being his 2013 rookie season with the Rockies, and the pandemic-shortened 2020 campaign.
Apart from an elite strikeout rate, Arenado’s 2025 numbers were pretty ugly across the board. He hit .237/.289/.377 with 12 home runs over 436 plate appearances in what ended up as his final season in St. Louis, and his barrel and hard-hit ball rates each ranked only in the 12th percentile of all hitters. Arenado’s numbers in those two categories were pretty similar in 2024, making it consecutive seasons of diminished power.
On the plus side, Arenado’s third base glovework was still strong, even if down from his Platinum Glove-winning prime years. So in swinging that trade with the Cardinals, the D’Backs could at least count on Arenado for solid defense and a veteran voice in the clubhouse. Even if Arenado’s bat was a question mark, it was a flier the Diamondbacks were willing to take given the modest $11MM price tag ($5MM in 2026, $6MM in 2027) and the fact that Arizona hadn’t been able to land such third base targets as Alex Bregman or Brendan Donovan.
Through two months of the season, Arenado seems to have benefited from the change of scenery. The 35-year-old has turned back to the clock to some extent by hitting .275/.357/.462 with seven home runs over 196 PA, translating to a 130 wRC+. If Arenado can keep this going over a full year, the 130 wRC+ would tie the third-highest mark of his 14-year big league career.
There was some thought that the move to Chase Field might spark Arenado’s bat, and sure enough, he has done more damage in a more hitter-friendly home ballpark. Arenado has a .934 OPS across 94 home PA, as opposed to a .711 OPS in 102 PA away from Phoenix.
His overall .360 wOBA is also notably higher than his .339 xwOBA, so some regression is probably inevitable (though .339 is still comfortably above the league average). Arenado still isn’t making contact with much authority, as his barrel rate is only up to 6.5% from 4% in 2025, and his hard-hit ball rate has actually dropped from 32.6% last year to 31.9% this year. While he is still making plenty of contact, Arenado’s 17.9% strikeout rate is on pace to be the second-highest of his career.
When Arenado has squared the ball, however, he has capitalized. As per Statcast’s launch angle sweet spot metric, Arenado’s number is up to 38.4% this season, putting him in the 81st percentile of all batters. (Comparatively, Arenado’s 31.5 LAS% in 2025 put him in the 16th percentile.)
All of this success comes after a very rough opening two weeks to the season, as Arenado started his D’Backs tenure with a .392 OPS over his first 52 plate appearances. It was around this time that Arenado and the hitting coaches made some swing changes, with the third baseman telling Nick Piecoro of the Arizona Republic that he was including too much head movement and not enough of his back hip while swinging. A new pregame routine was also introduced with the goal of, as Arenado put it, “trying to see shapes and pitches before I step in the box, so when I step in the box, it doesn’t feel like it’s the first time I’m doing it.”
Time will tell if Arenado can keep this going over an extended period of time, though his hot streak has now been going for almost a month and a half. Arenado’s production has basically offset an extended slump from shortstop Geraldo Perdomo, and helped keep the Snakes in a wild-card position and a game behind the Padres for second place in the NL West.
Even if Arenado does start to cool off, the D’Backs don’t need him to be the All-Star of his prime years — they just need him to produce like a $5MM player. Rather than looking like a plan B or C for the Diamondbacks’ third base needs, the Arenado trade is now shaping up as a nice bargain for the Snakes, and one of the cannier moves of the Arizona offseason.
