Astros Designate Dustin Harris For Assignment
The Astros announced a series of roster moves prior to tonight’s game. On the position player side, they reinstated infielder Nick Allen from the 10-day injured list and recalled infielder/outfielder Zach Dezenzo from Triple-A. In corresponding moves, they placed Yainer Diaz on the 10-day IL with a left oblique strain and designated outfielder Dustin Harris for assignment. The Diaz move was reported yesterday. On the pitching side, they recalled right-hander Jason Alexander and optioned fellow righty Ryan Weiss.
Harris, 26, was claimed off waivers a little more than two weeks ago. At the time, the Astros needed some help in the outfield. Dezenzo and Jake Meyers were both on the IL already. Joey Loperfido was also banged up and landed on the IL the next day. Zach Cole was on the IL in the minors.
Since being claimed, Harris has stolen four bases and been solid in the field but produced a tepid .226/.286/.290 line at the plate. That’s a small sample size of 11 games but it roughly matches his general profile. Harris is considered a speed-and-defense guy who isn’t likely to provide much with the bat. He has a .225/.307/.371 line in his big league career. His Triple-A line of .276/.366/.417 looks pretty solid but most of his time at that level has been in the hitter-friendly Pacific Coast League, so the line actually translates to a 101 wRC+, barely league average.
Both Cole and Dezenzo have now gotten healthy, which has squeezed Harris off the roster. Harris spent most of the past few years with the Rangers but exhausted his final option season in 2025. Texas outrighted him off the roster at the end of last season. He elected free agency and signed a minor league deal with the White Sox. He got a brief stint on Chicago’s roster before being put on waivers and claimed by Houston.
He now heads back into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so Houston could take five days to explore trade interest, though they could also put him on the wire sooner than that. If he clears waivers, he has the right to elect free agency since he has a previous career outright.
The Weiss option is also a notable development, since he was an interesting part of their offseason. The Astros needed rotation depth but had budgetary concerns. Weiss got a major league deal with a $2.6MM guarantee. He came into this year with no big league experience but had just finished a good season in South Korea. He made 30 starts for the Hanwha Eagles last year with a 2.87 earned run average, 28.6% strikeout rate, 7.7% walk rate and 48.5% ground ball rate.
If Weiss were able to put up similar numbers in North America, he could have been a sneaky bargain, but that has not panned out thus far. He has logged 26 innings in a swing role this season with a 7.62 ERA. His 22.9% strikeout rate is around average but he has walked 15.3% of batters faced, almost double league average. He’ll look to get back on track in Triple-A and could get another look with the Astros later in the year if he succeeds.

Diamondbacks Outright Aramis Garcia, Jesus Valdez
The Diamondbacks announced that they have outrighted catcher Aramis Garcia to Triple-A Reno and infielder Jesus Valdez to Double-A Amarillo. Garcia had been designated for assignment last week when Gabriel Moreno was activated from the 10-day injured list. There wasn’t any previous indication that Valdez had been removed from the 40-man roster. Arizona’s count on that 40-man is now down to 38.
Garcia, 33, is a veteran depth catcher who is out of options. He is a competent defender but is has hit just .210/.245/.321 in his career. That has put him in position to bounce on and off the Arizona roster with regularity. He signed a minor league deal with the Snakes ahead of the 2025 season. Last year, he was twice added to the big league roster. In both cases, he was designated for assignment a few days later and sent back to Reno after passing through waivers.
It’s possible the same sequence of events plays out this year. Garcia was called up to the big leagues to cover for Moreno’s injury and then was bumped off when Moreno was reinstated. Garcia has the right to elect free agency but might be comfortable sticking with the Aces and waiting for the next catching injury to pop up.
The Valdez outright might be a more unique situation. The 28-year-old was just added to the club’s roster a little over a week ago. The Diamondbacks and Padres were playing in Mexico City and were allowed a 27th man on the roster. Valdez was added to fill that extra bench spot for the Diamondbacks, getting called up from Double-A Amarillo. He didn’t appear in either of the Mexico City games and was optioned back to the Sod Poodles right after that series.
It appears that the Diamondbacks quietly put him on waivers and no one claimed him. That’s not especially surprising since Valdez hasn’t really been a notable prospect in his career and is a 28-year-old playing in Double-A, though he does have some Triple-A experience. Dating back to the start of 2021, he has a combined .241/.292/.401 line and 76 wRC+ in the minor leagues.

Brewers Release Jacob Waguespack
The Brewers have released right-hander Jacob Waguespack, who’s been pitching with their Triple-A affiliate in Nashville, Curt Hogg of the Milwaukee Journal-Sentinel reports. He’s free to explore opportunities with other clubs now.
Waguespack, 32, has pitched in parts of three big league seasons with the Blue Jays and Rays. He’s totaled only 105 2/3 innings in the majors and has a 5.11 ERA, 18.9% strikeout rate and 10.1% walk rate to show for his efforts.
Lack of big league track record notwithstanding, Waguespack’s 2026 work in Nashville has been quite strong. The well-traveled righty has tossed 16 innings and held opponents to a 2.25 ERA with a huge 33.8% strikeout rate and an even gaudier 17.4% swinging-strike rate. His 16.2% walk rate could obviously stand to improve. Waguespack is sitting 92.1 mph on his four-seamer and coupling the pitch with a mid-80s cutter and a low-80s changeup.
Waguespack last pitched in the majors with the Rays in 2024. He split the 2025 season between the Triple-A affiliates of the Rays and Phillies, combining for a 2.45 ERA in 33 innings. Overall, he’s pitched in parts of six seasons in Triple-A and has a 4.13 ERA in 285 2/3 innings there. Beyond his work at the top minor league level, Waguespack has pitched a pair of seasons for Japan’s Orix Buffaloes. He was excellent there in 2022 (2.97 ERA, 26.2 K%, 9.4 BB%, 72 2/3 innings) before struggling in 2023 (5.77 ERA, 33.3%, 12.9 BB%, 43 2/3 innings).
It’s common this time of year for veterans on minor league deals to reenter the market, whether via an opt out or simply being granted their release with no clear path to a spot in the current organization’s big league roster. They’ll sometimes simply return to the setting where they’ve already been playing, but if a team with a more dire need for bullpen help shows interest — even on a another minor league deal — that might prove to be a better arrangement for the journeyman Waguespack as he looks to push his way back into the majors.
Tigers Designate Zack Short For Assignment
The Tigers announced that infielder Zach McKinstry has been reinstated from the 10-day injured list. Fellow infielder Zack Short has been designated for assignment as the corresponding move.
Short is a glove-first infielder who was just brought into the mix by Detroit to address their recent injuries. He was acquired from the Nationals in a cash deal last week and then was added to the roster two days ago. He went hitless in three plate appearances and has now been quickly bumped off.
Though he’s competent in the field at multiple positions, Short is a .171/.269/.295 hitter in his career. The Tigers only really turned to him because they had a trio of infielders on the IL at the same time. McKinstry hit the IL over two weeks ago due to left hip/abdominal inflammation. Trey Sweeney has been on the shelf all year due to a shoulder strain and was moved to the 60-day IL in April. Javier Báez suffered a right ankle sprain about a week ago and hit the 10-day IL.
Short was used as an emergency tourniquet to stop the bleeding but he’s no longer needed with McKinstry’s return. Short now heads into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Tigers could take five days to explore trade interest, but they could also place him on waivers at any point before that. Given his light hitting, Short would likely clear waivers, as he has done before.
If he does clear waivers again, he would have the right to elect free agency, but perhaps he would stay. He is plenty familiar with the organization and the Detroit infield depth is still a bit light due to injuries, though they did add Paul DeJong via a minor league deal earlier today.
Now that McKinstry is back, he can return to the multi-positional role that he was in before. He has experience at the three infield spots to the left of first base and in the outfield as well. He’s at third base tonight with Colt Keith heading to the bench. Second base is mostly covered by Gleyber Torres but he has missed a few recent games due to side tightness, which has led to more playing time for Hao-Yu Lee. Shortstop was being shared by Kevin McGonigle and Báez but the IL stint for the latter has largely left that spot to McGonigle. With Parker Meadows on the IL, the outfield mix includes Matt Vierling, Wenceel Pérez, Riley Greene, Kerry Carpenter and Jahmai Jones.

Rays Place Steven Matz On IL With Elbow Inflammation
The Rays announced that left-hander Steven Matz has been placed on the 15-day injured list, retroactive to May 4th, with left elbow inflammation. Right-hander Chase Solesky has been selected to take his place on the active roster. The 40-man roster had a vacancy due to righty Yoendrys Gómez being designated for assignment a few days ago, so Solesky can take that vacated spot without a corresponding move.
Matz’s status is unclear. He has been having a good season so far, with a 3.86 earned run average through seven starts. He last took the ball on Sunday and pitched six innings of one-run ball against the Giants. Apparently, something has popped up between that start and today. The severity isn’t publicly known but it’s enough that the Rays are going to put him on the shelf for at least a couple of weeks.
The Tampa rotation has been good this year and has been a key part of their early-season success. The Rays are 22-12 and have gotten a 3.16 ERA from their starters. That includes some openers and is therefore skewed a bit but it’s third-best ERA in the majors, behind only the Yankees and Dodgers.
Despite the good results, there are some concerns. Ryan Pepiot is going to miss the whole season due to hip surgery. Joe Boyle is on the IL with an elbow strain. Even in the healthy rotation, there are questions. Shane McClanahan missed the entire 2024 and 2025 seasons and may face load management questions at some point. Drew Rasmussen has plenty of injuries on his track record. Nick Martinez has a 1.71 ERA but is a 35-year-old swingman who has often been pushed to the bullpen in recent years. Jesse Scholtens is a pretty inexperienced guy who was just claimed off waivers last year.
Top prospect Brody Hopkins is in Triple-A but probably isn’t going to be called up anytime soon because he has a massive 20.2% walk rate so far this year. The depth is enough of a concern that the club is planning to stretch out both Griffin Jax and Mason Englert.
The Rays will have to juggle things for at least a couple of weeks or perhaps longer, depending on the timeline with Matz. Their next off-day isn’t until next Thursday. Martinez started last night. Rasmussen and McClanahan are scheduled for tonight and tomorrow, respectively. Thursday could be a Jax/Scholtens combo, which is what the Rays have done the past two times through the rotation. That would leave Friday open for a bullpen game or a spot start, before going back to Martinez on Saturday.
Solesky, 28, gets called up for now. This is his first time on a major league roster. A 21st-round pick of the White Sox from 2019, he has never really been on the radar of prospect evaluators. He was in the Nationals’ system last year and had a 5.17 ERA in Triple-A. He signed a minor league deal with the Rays in the offseason and has a 6.57 ERA in Triple-A so far this year.
Most likely, he is just on the roster temporarily to absorb some innings, if needed. He has been pitching as a starter and went 5 1/3 innings on Thursday. The results haven’t been good but he could take on some mop-up work and spare the rest of the bullpen, if the situation calls for it. Even if it ultimately proves to be a brief stint in the show, it’s likely a thrill for a guy who has been grinding for a while and turns 29 in a few months.

Marlins Designate Chris Paddack For Assignment
1:08pm: The Marlins have now officially announced the Paddack and Kempner moves.
8:22am: The Marlins are designating veteran righty Chris Paddack for assignment, reports Ken Rosenthal of The Athletic. The team has yet to formally announce the move or a corresponding transaction, but Christina DeNicola of MLB.com reports that reliever William Kempner will be recalled from Triple-A Jacksonville. It’s Kempner’s first big league promotion. He’ll be making his MLB debut when he gets into a game.
It’s a hook on the 30-year-old Paddack, who signed a one-year, $4MM deal to return to the organization that originally drafted him (but traded him to the Padres in a 2016 swap for reliever Fernando Rodney). The hope had been that Paddack could provide some stable innings following offseason trades of Ryan Weathers (to the Yankees) and Edward Cabrera (to the Cubs). He looked great this spring (two runs, 13 innings pitched) but was shelled in seven regular season appearances with Miami (six of them starts).
Paddack only completed five frames once in his return to the Marlins organization: a quality start against his former Tigers teammates in Detroit (six innings, two runs). He allowed at least two runs in fewer than five innings each other time he took the mount, including a trio of appearances that saw him tagged for five, seven and eight runs apiece. His time with the Fish will draw to a close with a 7.63 ERA, an 18.5% strikeout rate and a 6.8% walk rate in 30 2/3 innings.
A former top prospect, Paddack debuted with a 3.33 ERA in 140 2/3 innings for the 2019 Padres. He’d have been a Rookie of the Year finalist, if not winner, in most seasons, but he happened to be up against Pete Alonso‘s 53-homer debut, Michael Soroka‘s 174 2/3 innings of 2.68 ERA ball, Fernando Tatis Jr. and Bryan Reynolds; excellent as Paddack’s debut was, he didn’t even receive a down-ballot vote.
Injuries have held Paddack back in the years since. He missed time with a UCL sprain in 2021 and then underwent his second career Tommy John surgery — his first came as a prospect — with the Twins in 2022. His 2024 season was cut short by a forearm strain.
In 471 2/3 innings since his terrific debut campaign, Paddack has posted a 5.23 ERA. He regularly shows strong command but has never missed bats at the same level he did as a rookie. He’s also been far too homer-prone, serving up an average of 1.55 round-trippers per nine frames from 2020-26.
It’s fair to wonder how many more rotation opportunities Paddack will get. He struggled out of the rotation more often than not in Minnesota, and the Tigers dropped him to the bullpen after just seven starts last summer following a trade to acquire him. The Marlins, obviously, are moving on in quick fashion.
Perhaps another club with a pile of rotation injuries will plug Paddack into its starting five when he’s inevitably released, but other clubs will surely be interested in what he might look like as a reliever. When Paddack returned from his second Tommy John procedure with the Twins late in the 2023 season, he pitched 8 2/3 innings between the regular season and postseason, allowing three runs with a 14-to-1 K/BB ratio. He looked particularly dominant in the postseason, and his typically 93 mph four-seamer was averaging 95.5 mph. He was hit hard out of the Detroit ‘pen last year, but they were using him as a long man, and not the short-relief role in which he excelled during that brief, post-surgery run with the Twins.
For the time being, the Marlins will have five days to trade Paddack or release him. (They could also place him on outright waivers, but he’d surely clear due to his salary and struggles, and Paddack has enough service time to reject an outright assignment while retaining his remaining guaranteed salary.) It’s possible they’ll find a taker who’s willing to pay a nominal portion of that guarantee, but the most common outcome in these scenarios is a simple release. The Marlins will remain on the hook for that $4MM salary. A new team would owe Paddack just the pro-rated league minimum for any time spent on the major league roster.
As for the 24-year-old Kempner, he came to the Marlins in a Jan. 2025 swap that sent international bonus pool space back to the Giants. The 2022 third-round pick had a big season in the minors last year between High-A, Double-A and Triple-A, combining for a 2.26 ERA with a 33.6% strikeout rate in 67 2/3 frames of relief. Command is a clear flaw, as Kempner walked 14.1% of his opponents along the way.
Kempner was selected to the 40-man roster back in November, thus shielding him from December’s Rule 5 Draft. He’s out to a tough start in ’26, with a 6.46 ERA in his first 15 1/3 frames at Triple-A. However, he’s fanned a preposterous 47.9% of opponents and allowed only a 63.8% contact rate. Kempner sits 95.5 mph with his heater and pairs it with a low-80s slider. He has a seldom-used cutter for a third offering but is primarily a two-pitch righty.
Kempner gives Miami a fresh arm for the next few days. Paddack’s spot in the rotation would be up this weekend. De Nicola lists Braxton Garrett and top prospect Robby Snelling as options to step into the rotation. Both pitchers have sub-2.00 ERAs with strong strikeout rates (Snelling in particular) but poor walk rates through their first handful of starts in Jacksonville.
MLBTR Chat Transcript
Steve Adams
- Good afternoon! I’ll get underway at the top of the hour, but feel free to start sending in questions ahead of time.
- Let’s get going
White Sox
- Since a 1-5 start, Sox are 16-13. Do you think they’ll finish within 3 games of .500 or better?
Steve Adams
- No. I just don’t think the pitching staff can support that level of winning. None of Burke, Martin, Kay or Fedde are average big league starters. Noah Schultz is super fun, and he very well could be, but he’s far from a sure thing yet and I expect some growing pains for him with the command issues.
John
- It’s too late to trade Mayo and Cowser imo. Do they have any value? Kjerstad as well. This team is so frustrating
Angel Zerpa To Undergo Tommy John Surgery
Brewers left-hander Angel Zerpa will undergo Tommy John surgery on Monday, reports Adam McCalvy of MLB.com. The left-hander will miss the remainder of this season and part of 2027 as well. He is on the 15-day injured list but will be transferred to the 60-day IL whenever Milwaukee needs to open a roster spot.
The news is awful but not surprising. Zerpa hit the IL about a week ago due to forearm tightness. Manager Pat Murphy said the injury was fairly concerning and that Zerpa would be going for further testing. In the following days, it was revealed that Tommy John surgery was a possibility. It now seems that no alternative was available, so Zerpa will go under the knife and face the standard recovery timeline of 14-plus months.
The Brewers clearly felt good about Zerpa’s chances of taking a step forward. He gave the Royals 177 innings from 2021 to 2025, allowing 3.97 earned runs per nine. His 19.7% strikeout rate was subpar but he had a strong 7% walk rate and excellent 57.1% ground ball rate. Milwaukee has a good reputation when it comes to helping players get the best of their talents. With Zerpa featuring upper-90s velocity, perhaps they could have found a way to have him miss more bats. Or maybe his ground ball tendencies could lead to him getting stretched out as a starter.
Milwaukee sent outfielder Isaac Collins and right-hander Nick Mears to Kansas City this past offseason in a two-for-one deal to get Zerpa. Whatever the Brewers had in mind for that deal is not going to pan out in the short term. Zerpa posted a rough 6.39 ERA in 12 appearances to start this year and will now be out of action until next summer.
Zerpa hit three years of big league service in 2025 and qualified for arbitration for the first time going into 2026. He and the Brewers agreed to a $1.095MM salary. He’ll be eligible for arbitration again for 2027 and 2028.
The Brewers will have to decide if they want to tender him a contract for next year when he might miss half of it. Since he is going to miss most of 2026, he won’t be able to secure much of a raise. Assuming the Brewers still feel good about Zerpa’s talent, giving him a bit over a million won’t be too much, since that is barely above this year’s league $780K minimum salary. It’s also possible that the next collective bargaining agreement pushes the minimum even higher. If Zerpa can get healthy and produce good results in the second half of 2027, the Brewers could retain him at a relatively affordable rate in 2028.
Despite having a number of injured lefties, the Brewers still have a balanced bullpen. Zerpa, Jared Koenig and Rob Zastryzny are all on the IL but they still have Aaron Ashby, DL Hall, Shane Drohan and Brian Fitzpatrick taking up four of their eight relief spots. Injuries and underperformance will surely lead to changes throughout the season. Zerpa won’t be able to help out but perhaps Koenig or Zastryzny will.

Braves Designate Carlos Carrasco For Assignment
The Braves announced Tuesday that veteran righty Carlos Carrasco has been designated for assignment. His spot on the roster goes to closer Raisel Iglesias, who has been reinstated from the 15-day injured list.
It’s the second time this season Atlanta has designated Carrasco for assignment. He seems quite amenable to being used as a de facto 41st man on the roster — being selected to the majors when an extra arm is needed, then riding the DFA carousel and re-signing a new minor league deal when he’s outrighted or released. He’s now been designated for assignment by the Braves three times dating back to last August. Each time he’s cleared waivers and re-signed. It’s the same gambit we saw with Atlanta and Jesse Chavez late in his career. Plenty of other clubs have done this with out-of-options pitchers in recent years as well (e.g. Mariners/Casey Lawrence, Yankees/Ryan Weber).
Carrasco has pitched in two games with the Braves this year. He’s logged 2 1/3 innings and held opponents scoreless on one hit and no walks with a pair of strikeouts. The former Cleveland ace has pitched well in Triple-A, too, tossing 21 innings (four starts) with a 1.71 earned run average.
At 39 years old, Carrasco is a good bet to again pass through waivers and return to Triple-A Gwinnett — whether by accepting an outright assignment or becoming a free agent and quickly re-signing, as he did after his most recent DFA in mid-April. Teams are typically very open and straightforward with veterans in this type of situation, so Carrasco is surely on board with the setup. It’s feasible that he’ll continue to pitch well enough that a team will eventually claim him off waivers, although in that scenario, he still makes out nicely, as he gets to stick in the big leagues and collect a major league paycheck even longer.
The Braves also noted that lefty Dylan Dodd is heading out on a rehab assignment with Triple-A Gwinnett. Shortstop Ha-Seong Kim‘s rehab assignment has been moved from Double-A to Triple-A as well. Both are on the mend and should be activated before too much longer.
MLB Issues Three-Game Suspension To Chris Devenski
Major League Baseball announced Tuesday that Pirates righty Chris Devenski has been given a three-game suspension and an undisclosed fine for what the league believes to have been intentionally throwing at Reds infielder Sal Stewart in Saturday’s game. That will go into effect tonight, unless Devenski files an appeal. He’d remain eligible to pitch while the appeal process plays out. Pittsburgh skipper Don Kelly also received a one-game suspension and an undisclosed fine. He’s expected to serve his suspension tonight.
The incident Saturday occurred in a game the Pirates led 15-to-6 (video link). Stewart stepped into the batter’s box and called time just as Devenski was coming set. He stepped out briefly, and upon digging back in was greeted with a 92 mph waist-high sinker that tailed inside and nearly hit Stewart. Although he managed to jump out of the way, Stewart was clearly perturbed and barked at Devenski, who walked several steps toward home plate. The umpiring crew convened and ultimately ejected Devenski, prompting an angry visit from Kelly.
“Going hard in to start an at-bat,” Devenski said after the game when asked about the ejection (video link). “I know the guy likes to dive over [the plate]. That’s about it. Just trying to execute my pitch there, and I think he took it the wrong way. It is what it is, but I’m not going to back down from anything, either.”
Devenski plainly stated that the pitch wasn’t intentionally thrown at Stewart. “[I’ve] been around the game a long time … If I was going to do anything like that…” Devenski trailed off with a light chuckle, seemingly implying that the location might’ve been different had there been true intent behind the pitch. “Not in that situation. Just trying to get outs,” he added.
The Pirates only selected Devenski to the major league roster last Friday. He’d been pitching in Triple-A Indianapolis on a minor league contract and pitching quite well, allowing just one run with a 15-to-2 K/BB ratio in 10 2/3 innings. He’s pitched 2 2/3 frames with the big league club and allowed a pair of runs on five hits and no walks with three strikeouts.
Time will tell whether Devenski appeals and whether the suspension holds up. If he opts not to appeal, the Pirates will play a man down for the next three games. On the plus side, the ‘pen is very fresh after Braxton Ashcraft worked 7 2/3 brilliant innings Sunday and the team had an off day yesterday.
