Luke Jackson Elects Free Agency
Aug. 10: Jackson cleared waivers and has chosen to become a free agent rather than accept an outright assignment to Triple-A Toledo, as per Jackson’s MLB.com profile page. Because Jackson has previously been outrighted in his career, he had the right to opt for free agency.
Aug. 8: The Tigers have recalled right-hander Codi Heuer from Triple-A Toledo, with fellow righty Luke Jackson designated for assignment. The moves haven’t been officially announced but Craig McCosky of Detroit News was among the reporters to relay them.
The Tigers picked up Jackson a couple of weeks ago after he had been released by the Rangers. He had been having a rough season in Texas but has a good track record, so the Tigers scooped him up, hoping for a bounceback.
Unfortunately, they didn’t get it. He tossed 4 2/3 innings for Detroit, allowing four earned runs via three hits and five walks while striking out four. Combined with his results with the Rangers, he has a 4.54 earned run average in 39 2/3 innings this year. His 52.5% ground ball rate is good but his 16.1% strikeout rate and 13.8% walk rate are both noticeably worse than league average.
Despite the rough numbers, he might get another shot somewhere. The Rangers are still on the hook for the remainder his $1.5MM salary. That means another club could sign Jackson and would only have to pay him the prorated version of the $760K league minimum for any time spent on the roster. That amount would be subtracted from what the Rangers pay.
From 2018 to 2024, Jackson tossed 289 2/3 innings in the majors with a 3.91 ERA. His 10.2% walk rate in that time was a bit high but he punched out 27.1% of batters faced and got opponents to hit the ball into the ground on 54.3% of balls in play.
The punchouts haven’t been there this year, which is why he’s now twice been designated for assignment. But with the trade deadline now passed, it’s harder for clubs to find useful pitching upgrades. Since Jackson has a good track record and would essentially be free, some team might take a shot on him soon.

Cardinals Claim Jorge Alcalá
Today: The Cardinals have formally added Alcalá to their active roster ahead of this evening’s game against the Cubs. In a corresponding move, Gordon Graceffo was optioned to Triple-A.
August 7: The Cardinals announce that they have claimed right-hander Jorge Alcalá off waivers from the Red Sox. Boston designated him for assignment earlier this week. The Cards had several 40-man roster openings from their deadline dealings. Alcalá is out of options, so the Cards will need to make a corresponding active roster move once he reports to the team.
Alcalá, 30, has a decent overall track record but is having a rough season. From 2019 to 2024, he pitched 163 1/3 innings for the Twins with a 3.64 earned run average. He struck out 25.4% of batters faced while giving out walks at an 8.3% clip. He earned one save and 28 holds in that time.
But as mentioned, this year has been a struggle. He posted some poor numbers earlier in the year and got flipped to the Red Sox in June. Between Minnesota and Boston, he has thrown 40 2/3 innings with a 6.64 ERA. His 24.2% strikeout rate is still a good number but he has given out free passes to 12.1% of opponents.
For the Cards, they’re only 5.5 games out of a playoff spot but clearly have their sights set on next season. They had planned for 2025 to be a reset year from the beginning. Even though they hung around the playoff race, they sold off impending free agents ahead of the deadline. That included three relievers, with Ryan Helsley traded to the Mets, Phil Maton to the Rangers and Steven Matz to the Red Sox.
Those trades left them with some openings on the roster. This is their second waiver claim since those deals. They grabbed Anthony Veneziano from the Marlins a few days ago and now have added Alcalá into the mix.
Alcalá is making $1.5MM this year and can be retained for 2026 via arbitration. His poor results this year will prevent him from earning a big raise. The Cards can get a close-up look at him for a few weeks and decide if they want to tender him a contract.

Diamondbacks Sign Nabil Crismatt To Minor League Deal
The Diamondbacks have signed right-hander Nabil Crismatt to a minor league deal, per an announcement from the Triple-A Reno Aces. Crismatt was previously with the Phillies on a minor league deal but was released a few days ago, according to his transactions tracker at MLB.com.
Crismatt, 30, has pitched 177 major league innings in his career with a 3.71 earned run average. His 21.5% strikeout rate is a bit south of average but his 7.2% walk rate and 50.3% ground ball rate are both solid figures. That includes a brief stint with the Diamondbacks in 2023, when he tossed two scoreless innings in his lone appearance as a Snake.
This year, he’s been stuck in the minors with the Phillies. He’s been working as a starter in Triple-A, making 19 starts with a 4.04 ERA, 16.2% strikeout rate, 6.2% walk rate and 40% ground ball rate.
The Diamondbacks have been hemorrhaging pitching this year. They have lost Corbin Burnes, A.J. Puk, Justin Martínez, Tommy Henry and Blake Walston to Tommy John surgeries. Additionally, Cristian Mena, Christian Montes De Oca, Ryan Thompson and Kevin Ginkel are on the injured list due to other reasons. Those injuries played a notable role in knocking the Diamondbacks out of contention, which led them to trading Merrill Kelly and Shelby Miller ahead of the deadline.
Given all of those fallen soldiers, the club may have some innings available down the stretch. Crismatt has worked both as a starter and a reliever in his career. He’ll give the Diamondbacks a depth arm for now but could perhaps be useful for the big league club as they play out the string on the season.

Astros Outright Luis Contreras
The Astros have sent right-hander Luis Contreras outright to Triple-A Sugar Land, according to his transactions tracker at MLB.com. He had been designated for assignment earlier this week when the club signed righty Enyel De Los Santos.
Contreras, 29, will stick with the Astros as non-roster depth. He has less than three years of big league service time and does not have a previous career outright. That means he does not have the right to reject this assignment and elect free agency.
He will therefore have to report to the Space Cowboys and try to pitch his way back onto the roster. His big league track record is still quite limited. He has pitched 18 innings for the Astros across this season and the 2024 campaign. He allowed 15 earned runs in that time via 18 hits and 10 walks while striking out 19. His minor league track record is greater in both quality and quantity. He has thrown 76 1/3 innings for the Space Cowboys since the start of 2024 with a 2.36 ERA, 25.2% strikeout rate and 12.7% walk rate.

White Sox Release Gus Varland
The White Sox have released right-hander Gus Varland, according to his transactions tracker at MLB.com. He was designated for assignment earlier this week when the Sox selected infielder Jacob Amaya.
A release was inevitable once Varland entered DFA limbo. A trade wasn’t possible since the deadline had passed. Varland was also on the minor league injured list at the time of his DFA. Injured players can’t be placed on outright waivers.
He’ll now head to the open market and see what offers await him. He won’t be able to help any club in the short term. Per Scott Merkin of MLB.com, a forearm strain sent him to the IL earlier this year. James Fegan of Sox Machine reports that Varland now has a lat strain, suggesting he may be out for the rest of the year.
Clubs should still be interested in Varland as a long-term play. The 28-year-old has some major league success on his track record. Overall, he has a 4.82 earned run average in 46 2/3 innings, but his most recent big league stretch was better than that. The Sox claimed him off waivers from the Dodgers in August of last year. After that claim, he went on to toss 20 1/3 innings for the Sox down the stretch with a 3.54 ERA, 28.2% strikeout rate, 4.7% walk rate and 40.4% ground ball rate.
Here in 2025, he had a rough spring and started the season on optional assignment in the minors. He made just two appearances before landing on the IL. He tried rehabbing in June but that rehab assignment only lasted six appearances. Varland will still have an option remaining after this season and less than a year of service time. Even though he can’t help this year, teams will be interested in him for 2026 and beyond.

Minor MLB Transactions: 8/9/25
Leading up to the trade deadline, dozens of moves were made. In the wake of those trades, several players were designated for assignment. Here are the results of a few recent DFAs which MLBTR hasn’t yet covered…
- Right-hander Sean Hjelle has been sent outright to Triple-A Sacramento, per his transactions tracker at MLB.com. He was designated for assignment by the Giants when they traded Tyler Rogers to the Mets. Two of the players the Giants received, José Buttó and Blade Tidwell, required 40-man roster spots. The departure of Rogers opened one spot, with Hjelle DFA’d to open another. This was Hjelle’s first career outright and he has less than three years of service time, meaning he didn’t have the right to elect free agency. He will give the Giants non-roster depth and try to earn his way back to the majors. His Triple-A numbers have been good this year, having tossed 41 2/3 innings with a 2.81 ERA, 25.7% strikeout rate, 5.7% walk rate and 52.7% ground ball rate.
- Left-hander Zach Penrod has been outrighted to Triple-A Oklahoma City, per his transactions tracker at MLB.com. He was designated for assignment by the Dodgers when left-hander Blake Snell was reinstated from the 60-day injured list. This was his first career outright and he has less than three years of big league service time, meaning he had to accept the assignment. Penrod was just acquired from the Red Sox in a DFA trade in June and was kept on optional assignment, so he still hasn’t pitched for the Dodgers in the majors.
- Right-hander Connor Gillispie has been outrighted to Triple-A St. Paul, per his transactions tracker at MLB.com. He had been designated for assignment by the Twins in late July when Michael Tonkin was selected. This was Gillispie’s first career outright and he has less than three years of big league service time, meaning he had to accept the assignment. He reported to the Saints but they put him on the minor league injured list a few days later. It’s unclear what his current health status is but he hasn’t pitched since July 27th.
- Right-hander Geoff Hartlieb is back with the Tigers on a minor league deal, according to his transactions tracker at MLB.com. He was designated for assignment in late July when Detroit signed Luke Jackson. Hartlieb cleared waivers and elected free agency, which was his right as a player with a previous career outright, but reunited with the Tigers on a new minor league deal. He has a 7.95 career ERA in the majors but better minor league numbers. He has tossed 41 Triple-A innings this year with a 3.29 ERA, 27.5% strikeout rate, 6% walk rate and 40.6% ground ball rate.

Giants Select Drew Gilbert, Designate Daniel Johnson For Assignment
The Giants announced that outfielder Jerar Encarnación has been placed on the 10-day injured list, retroactive to August 7th, with a right hamstring strain. To fill his spot on the active roster, they have selected outfielder Drew Gilbert. To open a 40-man spot for Gilbert, outfielder Daniel Johnson has been designated for assignment.
Gilbert, 24, has been in the system less than two weeks. He was one of three players the Giants acquired when trading Tyler Rogers to the Mets ahead of the deadline. That was actually the second trade of Gilbert’s career. Originally drafted by the Astros, he was sent to the Mets in the 2023 deadline deal which sent Justin Verlander back to Houston.
Though he was once seen as a top 100 prospect, his stock isn’t quite that high anymore. Baseball America ranked him as the #77 prospect in all of baseball ahead of the 2023 season. Gilbert had just been drafted 28th overall in the summer of 2022. He then made his professional debut by playing ten games in the lower levels of Houston’s system, slashing .313/.405/.531 in a tiny sample of 39 plate appearances.
As he has climbed the minor league ladder, he has continued to perform, though it’s possible he may be a decent all-around player without a standout tool. This year, he has 408 minor league plate appearances. His 12.3% walk rate and 16.2% strikeout rate are both better than average. He has hit 14 home runs and stolen six bases. His combined .262/.369/.466 batting line leads to a 119 wRC+. He has played all three outfield positions.
BA listed him as the #14 prospect in the Mets’ system prior to last month’s trade. They note that he is basically decent at everything. He makes contact and hits a few home runs. He’s an above-average runner. While he can hold his own in center, he might be destined for right field.
For the Giants, he’s a sensible flier to take. Rogers is 34 years old and was about to hit free agency. Once the club slid in the standings, they made it their priority to focus on the future. They also traded Mike Yastrzemski, opening some outfield playing time. Encarnación’s injury opens up some more, at least for the short term.
Going into next year, the Giants have two outfield spots spoken for by Jung Hoo Lee and Heliot Ramos. They can use the remainder of their season to get a look at Gilbert and see if he can earn a spot. Guys like Grant McCray, Luis Matos, Marco Luciano and Wade Meckler could also be in the mix, though the latter three are all on pace to be out of options next year. That could make it harder for them to hold a 40-man spot through the winter.
Johnson, 30, signed a minor league deal with the Giants in May. He was selected to the 40-man roster in June. He has since slashed .172/.226/.345 in 31 plate appearances. That gives him a career .193/.238/.336 line in 126 trips to the plate, dating back to his 2020 debut.
Now that he’s been bumped into DFA limbo and the trade deadline has passed, he’ll have to be placed on waivers. He has generally hit well in the minors. Dating back to the start of 2023, he has a combined .267/.333/.469 line and 107 wRC+ on the farm. He is still optionable for the rest of this season but will be out of options next year.

Rockies Select Kyle Karros, Aaron Schunk
The Rockies announced that they have selected the contract of infielders Kyle Karros and Aaron Schunk. Thomas Harding of MLB.com reported on those promotions prior to the official announcement. In corresponding moves, they have placed infielder Orlando Arcia on the 10-day injured list due to right elbow inflammation, transferred infielder Thairo Estrada to the 60-day IL and placed right-hander Angel Chivilli on the restricted list. It’s unclear why Chivilli has been placed on the restricted list.
Karros, 23, is the son of Eric Karros. The younger Karros was Colorado’s fifth-round draft pick in 2023. Since then, he has been climbing the minor league ladder, generally putting up good numbers. He has taken 1,010 minor league plate appearances across multiple levels with an 11.5% walk rate, 20.4% strikeout rate, .304/.393/.459 batting line and 135 wRC+. That includes a .301/.398/.476 line this year, mostly at Double-A but also with a few games at the Complex League and at Triple-A.
Baseball America currently lists him as the #14 prospect in the Rockies’ system. Their report notes that he is a strong defender at third base with a good arm. His offensive profile is highlighted by his contact ability, which matches with his numbers. His strikeout and walk numbers are good but he doesn’t appear to have a ton of power. He hit 15 home runs in High-A last year but has just six so far in 2025.
Schunk, 28, was outrighted off the roster in June. He has a dismal .230/.254/.311 line in 127 big league plate appearances. His minor league work has been better but still subpar. From 2023 to the present, he has 1,065 Triple-A plate appearances. His .293/.344/.469 line in that time looks impressive at first glance but actually translates to an 87 wRC+ in the context of the hitter-friendly Pacific Coast League.
The Colorado infield took a few recent hits. Estrada landed on the 10-day IL two days ago due to a right hamstring strain. With today’s transfer to the 60-day IL, his season is done. With Arcia landing on the 10-day IL today, that’s two infield vacancies created this week. The club also lost Ryan Ritter to the IL last month due to a finger laceration.
Those injuries have created openings for Karros and Schunk. The Rockies don’t have a lot to play for this year but have long-term opportunities available. Aside from Ezequiel Tovar at shortstop, there’s not much certainty in the infield for future seasons. Guys like Warming Bernabel and Adael Amador are already getting some big league at-bats and now Karros and Schunk can join them.
Circling back to Estrada, this is the final nail in the coffin for his very challenging season. He had a solid three-year run with the Giants from 2021 to 2023. He slashed .266/.320/.416 for a 105 wRC+ in that time while stealing 45 bases and bouncing around the diamond to all three outfield spots and the three infield positions to the left of first base.
He had a rough campaign last year, however. He went to the IL multiple times due to left wrist sprains and slashed just .217/.247/.343 for a 65 wRC+. The Rockies gave him $4MM for 2025 with the hope of a return to form, a logical bet for a rebuilding club. If Estrada had been able to get back to his previous level of production, he could have been an intriguing midseason trade candidate.
That did not come to pass. He was hit by a pitch in spring training and broke his right wrist. That put him on the IL for the first two months of the season. He also missed time with a sprained left thumb and now this hamstring strain has put him out for the rest of the campaign. Around those injuries, he only got into 39 games and hit .253/.285/.370. He can be retained for 2026 via arbitration but is surely going to be non-tendered. He will return to the open market but his appeal should be light on the heels of these two injury-marred seasons.

Rays Designate Connor Seabold For Assignment, Select Tristan Peters
The Rays announced that they have placed outfielder Jonny DeLuca on the 10-day injured list, retroactive to August 7th, with a left hamstring strain. They have selected fellow outfielder Tristan Peters to take his active roster spot. To open a 40-man spot for Peters, right-hander Connor Seabold has been designated for assignment. Marc Topkin of the Tampa Bay Times reported on the moves prior to the official announcement.
Peters, 25, gets called up to the big leagues for the first time. The Brewers selected him in the seventh round of the 2021 draft. He was sent to the Giants in the 2022 trade which sent Trevor Rosenthal to Milwaukee. A few months later, he was flipped to the Rays in the deal which sent Brett Wisely to the Giants.
Since joining the Rays, Peters’ offense has been up and down. Splitting his time between Double-A and Triple-A, he has a combined .264/.358/.425 line since the start of 2023. His 11.8% walk rate and 17.5% strikeout rate are both decent figures. However, he has modest power. His career high for home runs in a season is 12, set last year. He was on pace to get past that, having hit 11 so far in Triple-A this season. His 2025 slash line is .282/.370/.453, good for a 117 wRC+.
He doesn’t show up on lists of the top prospects in the system but he seems to be a solidly well-rounded player. His strikeout and walk rates are better than par. He doesn’t hit a ton of home runs but has notched a few. He generally gets to double digits in terms of stolen bases as well, having swiped 11 bags this year. He has also played all three outfield spots. He’ll jump into the club’s outfield mix, replacing DeLuca. Since this is his first time coming up to the show, he has a full slate of options and can be easily sent back down in the future.
Seabold, 29, signed a minor league deal with the Rays in the offseason. He was selected to the big league roster in May but he has largely been on optional assignment since then. He has only appeared in three games of the Rays, having tossed 6 2/3 innings, allowing one earned run on seven hits and three walks while striking out seven.
His work in the minors hasn’t been strong this year. He has been in a swing role, having made ten starts and six relief appearances. In his 61 innings, he has a 6.49 ERA, 21% strikeout rate and 9.6% walk rate.
Seabold now heads into DFA limbo. Since the trade deadline has passed, he’ll be placed on waivers soon, if he hasn’t already. It’s been a few years since he looked good in affiliated ball but he had a good year in Korea in 2024. He tossed 160 innings for the Samsung Lions with a 3.43 ERA, 23.8% strikeout rate and 6% walk rate.

Orioles Sign Greg Allen To Major League Deal
The Orioles announced that they have signed outfielder Greg Allen to a major league deal. A roster spot was vacated earlier when infielder/outfielder Vidal Bruján was claimed off waivers by Atlanta. Allen had been with the Cubs on a minor league deal but was released a few days ago, per his transactions tracker at MLB.com. The O’s also reinstated first baseman Ryan Mountcastle from the 60-day injured list and recalled outfielder Jordyn Adams. Those two will take the spots of outfielders Colton Cowser and Tyler O’Neill. Cowser has been placed on the seven-day concussion IL, retroactive to August 7, and O’Neill on the 10-day IL, retroactive to August 6, due to right wrist inflammation. The O’s had 40-man vacancies for Mountcastle, so no corresponding move was required in that regard.
Allen has been playing fairly well for Triple-A Iowa this year, with a .270/.355/.440 line and 105 wRC+ in 231 plate appearances. He also stole 11 bases while playing all three outfield positions. Given that solid performance, it’s possible he opted out of that pact, rather than simply being released.
Regardless, the result is he gets an opportunity with the O’s. He has had big league chances before but without much success, having slashed .231/.300/.340 in 828 plate appearances from 2017 to 2023. However, he stole 48 bases in that time and got some strong marks for his glovework in the outfield.
The O’s opened up some playing time in their outfield recently. Ahead of the deadline, they traded both Ramón Laureano and Ryan O’Hearn to the Padres, in addition to flipping Cedric Mullins to the Mets. Calling up Heston Kjerstad would have made sense but he’s been shut down due to fatigue, per Danielle Allentuck of the Baltimore Banner.
Lately, Coswer, O’Neill, Jeremiah Jackson and Dylan Carlson have been sharing the outfield time. With Cowser and O’Neill now heading to the IL, Allen and Adams give them some other outfielders who can factor into the mix. Allen is out of options, so if the O’s want to remove him from the active roster at any point, he would need to be removed from the 40-man entirely.
As for Mountcastle, he’s looking to put a nice finish on what has otherwise been an awful year. He hit .246/.280/.348 in 52 games before a hamstring strain sent him to the IL at the end of May. The O’s can retain him for 2026 via arbitration but he likely needs to show them something good down the stretch for that to be a possibility. He is already making $6.787M this year. His results this year will hurt his earning power but he would be due at least a nominal raise.
He came into this year with a career .265/.316/.450 batting line and 111 wRC+. If he can hit like that for a few weeks, perhaps the O’s will bring him back next year. He’s in the designated hitter spot tonight with Coby Mayo playing first base.
