Astros right-hander Tatsuya Imai landed on the 15-day injured list on April 13 with what the team called right arm fatigue, but he is progressing well in his rehab. Imai is set to throw a bullpen session tomorrow and could begin a minor-league rehab assignment as early as Tuesday, according to manager Joe Espada (via Chandler Rome of The Athletic). Although the exact nature of his arm fatigue isn’t clear, the team is surely hoping he’ll be back sooner rather than later.
Imai signed a three-year, $54MM deal with the club over the offseason, which fell below industry expectations for the former Japanese star. He has had a rough beginning, allowing seven earned runs and 11 unintentional walks in just 8 2/3 innings over three starts. That’s a very small sample, of course, and there is still plenty of time for Imai to establish himself as a big-league starter. For the Astros, the big picture concern is the fact that so many of their starting pitchers are injured right now. Hunter Brown and Cristian Javier are both out with Grade 2 right shoulder strains and won’t return for another 4-6 weeks. The struggling pitching staff, which has a 5.97 ERA overall, is the main reason the club is out to a 10-18 start in 2026.
A couple other injury notes from the AL West:
- Angels catcher Logan O’Hoppe was removed from today’s game due to left wrist irritation, the team announced. O’Hoppe took a foul ball off his wrist and finished the inning after being visited by the trainer. Travis d’Arnaud took over behind the plate in the eighth. O’Hoppe is now in his third season as the club’s starting catcher, though he has not been a productive hitter since 2024, when he posted a 102 wRC+ in 522 plate appearances. He declined in 2025, posting a mere 72 wRC+, and has been about the same to start 2026. It is unclear whether O’Hoppe will miss any time. Given the wrist irritation is in his receiving hand, the club might opt to play it safe for the next few days to avoid compromising his defense. He and d’Arnaud are the only catchers on the 40-man roster, so any absence might motivate the team to scour the waiver wire for a depth option.
- Rangers left-hander Jordan Montgomery threw a bullpen session today and will have at least one more before progressing to face live hitters, according to Shawn McFarland of the Dallas Morning News. Based on that, he seems to be on track in his recovery from March 2025. Montgomery signed a one-year, major-league deal with the Rangers in February, with the expectation that he would start the year on the 60-day injured list before returning later in the season. His last season as an effective starter was in 2023, when he was worth 4.2 fWAR in 32 starts between the Cardinals and the World-Series winning Rangers. Now 33 and coming off an extended absence, he won’t be expected to replicate that upon his return. In the best case for Montgomery, he could slot in as a back-end arm if Jacob deGrom or Nathan Eovaldi gets injured or one of Kumar Rocker and Jack Leiter underperforms.
