Shinnosuke Abe left a game on March 15 early because of some tightness in his legs. Since then, he has spent most of his time either as a designated hitter or bat off the bench. He may be having trouble adjusting his workload: he took thing slow last year and ended up hurting his right shoulder before the start of the season; he increased his workouts this year and may have ended up overworking himself.
Abe was able to return to the starting line-up yesterday against Nippon Ham and went 0-for-3 (F9, G4, F8, BB).
