Mariners vs Astros

Donovan is eligible to return from the IL as of Tuesday, but the M's will give him a few extra days to recover before activating him. The 29-year-old infielder has been going through workouts and baseball activities back in Seattle for the past few days, which suggests he could be ready for the start of the team's weekend series against the Royals.

After recording just five outs on 33 pitches in his first rehab appearance with Triple-A Tacoma on April 18, Miller moved down a couple levels for his second minor-league start and delivered a much more efficient performance. During Friday's outing, he spotted 35 of his 47 pitches for strikes and induced eight swings and misses while sporting a fastball that sat between 96 and 98 miles per hour. Per MLB.com, Miller is tentatively trending toward a return from the 15-day injured list May 17, which suggests he'll need three more rehab starts prior to being activated. The right-hander has been on the shelf all season while recovering from a left oblique strain.

The transaction will clear a spot on the 40-man roster for the addition of Connor Joe. Vargas has been out all season while recuperating from a right lat strain and now is not eligible to return until late May. It's not clear whether Vargas has resumed throwing or remains shut down.

Evans missed several weeks during the second half of last season with right elbow inflammation, so it's possible he had UCL damage for a while that was only recently discovered. He will miss the entire 2026 season and, given the timing of the procedure, could get a late start to the 2027 campaign, as well. Evans had been likely to open the upcoming season at Triple-A Tacoma, but his absence is a blow to the Mariners' pitching depth. The 24-year-old posted a 4.32 ERA and 59:31 K:BB over 81.1 innings covering 15 starts and one relief outing last season.

Mastrobuoni had been in the midst of a rehab assignment with Triple-A Tacoma and appeared to be on the cusp of a return from the 10-day IL, but his move to the 60-day IL likely indicates that he suffered some sort of setback over the weekend. As a result of the transaction, Mastrobuoni now won't be eligible to make his 2026 debut with the Mariners until the final week of May, though an exact timeline for his activation is unclear. The utility player initially suffered the right calf strain in March while playing for Team Italy in the World Baseball Classic.

Wisdom may have picked up the injury during his last outing Tuesday against the Padres, when he struck out in his lone plate appearance. Wisdom is eligible to be activated from the IL in late April, though oblique injuries tend to take more time to recover from. Rob Refsnyder (personal) was activated from the Mariners' paternity list in a corresponding move.

The 28-year-old landed on the shelf last week due to a right pectoral strain, and the Mariners are building him back up slowly since it's an injury to his throwing arm. Robles will be eligible to be reinstated Friday but seems likely to require a longer stint on the IL.

The deal includes an invitation to major-league spring training. Jacques collected a 6.02 ERA and 61:23 K:BB over 52.1 innings at the Triple-A level in 2025. The left-handed reliever will compete for a bullpen job during spring training.

Brash threw just two pitches in the eighth inning during his appearances Wednesday before leaving the game alongside a trainer. It doesn't seem like the 27-year-old righty is dealing with anything serious, and he'll have a day off Thursday to recover before the Mariners begin their next series against the Royals on Friday.

Bolton had made three appearances (two starts) and pitched to a 5.40 ERA and 1.68 WHIP over 8.1 innings before landing on the shelf April 15 due to mid-back inflammation. The right-hander appears to be tracking toward a brief stay on the IL, as he was able to make a two-inning rehab appearance for Triple-A Sugar Land on Sunday. While Houston still has six other starting pitchers on its IL, Bolton may be ticketed for the bullpen once activated with the Astros having received strong results from Spencer Arrighetti and Peter Lambert since those two pitchers entered the rotation.

Javier's initial placement on the 15-day IL was retroactive to April 9, so his move to the 60-day IL ensures that he'll be on the shelf through at least the first week of June while he recovers from a Grade 2 right shoulder strain. Given the length of his absence along with his poor numbers prior to landing on the shelf (12.54 ERA, 2.36 WHIP and 4:9 K:BB in 9.1 innings over three starts), Javier likely won't be worth holding in the majority of fantasy leagues.

It's a significant step in Brown's rehab from a shoulder strain. Sidelined since throwing six innings of one-run ball with eight strikeouts against the Red Sox on March 31, Brown is expected to be sidelined through late May, according to GM Dana Brown. Once he builds his arm back up, Brown will likely require a multi-start rehab assignment.

Meyers checked his swing on a Michael Lorenzen pitch but tweaked something in the process. He will likely be sent for an MRI to gain more clarity on the injury. Should Meyers have to miss time, Joey Loperfido and Brice Matthews are candidates for more playing time in center field.

Pena was cleared to begin running last week, and he appears to be making strides in his recovery from a right hamstring strain now that he's received the green light to face live pitching. Manager Joe Espada added that the 28-year-old infielder is close to beginning a rehab assignment in the minor leagues, though he remains without a firm return timeline.

Loperfido is with the team in Cleveland for its brief three-game road trip, which is a good omen for his prospects of a quick return. He will be eligible for activation from the 10-day injured list April 28.

Allen was originally in Saturday's lineup but ultimately was unable to take the field. Original reports suggested he was available for Saturday's game, though it appears that likely wasn't the case. The severity of the issue is not clear.

Imai tossed two innings, allowing five runs on six hits and three walks while striking out two batters during his first rehab start with Double-A Corpus Christi on Tuesday. Manager Joe Espada announced Thursday that the right-hander will make another start while on his rehab assignment, though it's currently unclear at what level his next outing will come. Imai has been sidelined since April 13 while recovering from right arm fatigue, and the additional time away may have allowed him to better adjust to life in the United States, which was something else he was reportedly struggling with, per Jack Baer of Yahoo Sports.

Trammell suffered a left groin injury while running the bases Monday, and it sounds as though he'll require a trip to the injured list. An official move should come at some point Tuesday. Dustin Harris and Brice Matthews could see more time in center field while Trammell is sidelined.

Dezenzo sustained a sprained elbow while playing for Team Italy in the World Baseball Classic last month. The 25-year-old appeared in 34 games for the Astros last season, slashing .245/.321/.367 with two homers, 10 RBI, 17 runs scored, one stolen base and an 11:37 BB:K across 109 plate appearances.

Weiss was ineffective in two starts after entering the Astros rotation, allowing a total of four runs on eight hits and eight walks over seven innings. Teng isn't fully stretched out to handle a typical starter's workload, so Weiss could be needed in long relief Tuesday. Weiss has collected a 6.50 ERA, 2.17 WHIP and 22:14 K:BB over 18 innings covering two starts and five relief outings this season.
