Tatsuya Imai: Breaking News

Rejoining rotation Tuesday

Imai (arm) will be reinstated from the 15-day injured list to start Tuesday against the Mariners, Chandler Rome of The Athletic reports. The right-hander has been on the shelf about a month due to arm fatigue, but he's ready to re-enter Houston's rotation after two rehab starts in the minor leagues. Imai threw 63 pitches over three innings during his final rehab outing, so he should have some workload limitations in his first couple starts back with the Astros. Prior to the absence, the 28-year-old surrendered seven earned runs with a 13:11 K:BB over 8.2 frames in his first three big-league starts.

Next start will be in majors

Astros general manager Dana Brown said Tuesday that Imai (arm) will rejoin the rotation next week versus the Mariners, Chandler Rome of The Athletic reports. If Imai is kept on a schedule of five days of rest in between starts, he's be in line to start Monday's series opener. He 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. 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. 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.
