Tatsuya Imai Undergoes Testing for Right Arm Fatigue

Astros rookie pitcher Tatsuya Imai returned to Houston to undergo medical examinations for right arm fatigue following his third start. Manager Joe Espada described the situation as "not good news," adding to the team's pitching concerns. The right-hander has struggled to adapt to MLB since transitioning from Japan, and the team has been utilizing Christian Vazquez as his personal catcher to assist in his rhythm.
