What It Means:

Osuna has been bothered by the back injury for a few weeks now, but the assumption was he would be good once the season started. Obviously not true anymore. There is no timetable for his return, but Jason Grilli will likely serve as the Team's closer at least for a couple of weeks.

Grilli recorded two saves for the Blue Jays last season. He is projected to post a 3.72 ERA and 1.27 WHIP in 55 2/3 innings this season by our algorithms.
