Astros' Tatsuya Imai to make return next week following rehab stint | Sporting News The Astros are set to regain an important arm in their rotation.

Next start will be in majors Astros manager Joe Espada said Tuesday that Imai's (arm) next start will be in the majors, Matt Kawahara of the Houston Chronicle reports.

Impact Imai made his second rehab start Tuesday with Triple-A Sugar Land, allowing one run on one hit with a 3:5 K:BB over three innings. The right-hander has not yet made a start on four days' rest, so if he's kept on that schedule, the earliest he'd rejoin the Astros' rotation is Monday at home against the Mariners. Imai -- who is coming back from fatigue in his pitching arm -- threw 63 pitches Tuesday, so he will not be ready for a full workload in his first start back with the big club.

Rehab moving to Triple-A Imai (arm) will make his next rehab appearance Tuesday or Wednesday with Triple-A Sugar Land, Brian McTaggart of MLB.com reports.

Impact The Japanese right-hander made his first rehab appearance with Double-A Corpus Christi on Tuesday, allowing five runs over two innings. Imai struggled to a 7.27 ERA and a 13:11 K:BB in his first three MLB starts before landing on the shelf, so he's likely to need another rehab start or two after next week's outing.

Expected to log another rehab start Imai (arm) will make another start during his minor-league rehab assignment in the coming week, Chandler Rome of The Athletic reports.

Impact 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.

Struggles in first rehab start Imai (arm) was charged with five runs on six hits and three walks over two innings in his first rehab start with Double-A Corpus Christi on Tuesday.

Impact It's not the bottom-line result the Astros were looking for from Imai, who threw 59 pitches over his two innings of work. The Japanese right-hander will require at least one more rehab outing as he continues to ramp back up. Imai has been sidelined for more than two weeks with fatigue in his pitching arm.

Astros righty Tatsuya Imai to begin a rehab assignment at Double-A on Tuesday

Houston Astros right-hander Tatsuya Imai is expected to begin a rehab assignment with Double-A Corpus Christi on Tuesday

APRIL 26 • Associated Press

Will begin rehab stint Tuesday Imai (arm) is slated to begin a minor-league rehab assignment with Double-A Corpus Christi on Tuesday, Chandler Rome of The Athletic reports.

Impact Imai landed on the IL due to right arm fatigue April 13. Imaging came back clean, and the Japanese hurler has been building up his workload since, including by tossing 45 pitches in a bullpen session Friday. Imai will now progress to game action with Corpus Christi and appears to be on track to rejoin the Astros in the first half of May.

Nearing rehab assignment Astros manager Joe Espada told reporters that Imai's (arm) bullpen session Friday "looked good," and that the right-hander's next step is to embark on a rehab assignment, Brian McT...

Impact Imai has been steadily building up his workload since landing on the 15-day injured list April 13 due to right arm fatigue. It appears the 27-year-old is ready to take the next step in his recovery program by going on a rehab assignment, and he'll likely need at least a couple of outings without a setback before returning to the majors.

Throws off mound Imai (arm) threw a bullpen session Monday, Matt Kawahara of the Houston Chronicle reports.

Impact It appears to be the first time he has thrown off the mound since landed on the 15-day injured list a week ago with right arm fatigue. The Astros haven't revealed the next steps for Imai, but it will likely involve facing hitters and perhaps making a rehab start or two. Imai holds a 7.27 ERA and 13:11 K:BB over his first 8.2 innings with Houston.

Plays catch Thursday Imai (arm) played catch at Daikin Park on Thursday, Matt Kawahara of the Houston Chronicle reports.

Impact Imai landed on the injured list Monday due to right arm fatigue, but imaging came back clean and he has begun a throwing progression. The right-hander is eligible to return later this month, but a timetable for Imai rejoining the Astros' rotation won't be available until he further ramps things up.
