Tatsuya Imai: Breaking News

Hurt by the long ball in loss

Imai (1-2) took the loss Monday against the Twins, allowing three runs on five hits and no walks with five strikeouts across 4.2 innings. All three of the runs against Imai came on a pair of homers by Josh Bell. Otherwise, Imai's stuff looked good, as he generated a season-high 19 whiffs on 74 pitches. In two starts since returning from arm fatigue, Imai has surrendered nine runs on 10 hits and three walks with eight strikeouts across 8.2 innings. He's been hurt by the long ball in both outings, surrendering four round-trippers. On the season, Imai owns an ugly 8.31 ERA, 1.79 WHIP and 21:14 K:BB across 17.1 innings. Walks have been a problem, as he'd walked at least three in each of his first four starts before issuing zero Monday.

Takes loss in return

Imai (1-1) allowed six runs on five hits, three walks and two hit batsmen while striking out three over four innings to take the loss Tuesday versus the Mariners. Imai missed a month due to right arm fatigue. He gave up two big knocks Tuesday, a two-run home run to Randy Arozarena in the second inning and a grand slam to Dominic Canzone in the fourth. Those were the first two homers Imai has allowed in his major-league career. He threw 46 of 80 pitches for strikes in his return from the injured list, so his workload may need to be monitored going forward. With a 9.24 ERA, 2.05 WHIP and 16:14 K:BB over 12.2 innings across four starts, Imai hasn't done much yet to impress in fantasy. He is tentatively projected to make his next start on the road in Minnesota.

Back from IL

The Astros reinstated Imai (arm) from the 15-day injured list to start Tuesday's game against the Mariners, Julia Morales of Space City Home Network reports. Imai is ready to rejoin Houston's starting rotation after spending on a month on the IL due to right arm fatigue. The 28-year-old built up to just 63 pitches across three innings during his second of two rehab outings, so the Astros plan to limit his workload to around 80-to-85 pitches Tuesday, per Chandler Rome of The Athletic.
