Rosenthal was placed on the DL with a right lat injury just before Opening Night. He appeared in 5 games in spring training going 1-0 with a 1.80 ERA in 10 innings of work while striking out 11.
A healthy Rosenthal could be a boost for a bullpen that has allowed 13 earned runs over 17.1 innings of work through their first six games this season. But that is based on the hope that he has straightened out the struggles he had last year where he lost the closer’s job to Seung-hwan Oh.
Tuivailala will return to Memphis. He made 3 appearances and allowed 1 run in 3 innings of work while striking out two.
