What happened: Jonathan Bowlan is dealing with a groin issue that has kept him from throwing, even without an injured-list move. Philadelphia is also working around a thinner staff with Jesus Luzardo already sidelined and another bullpen arm lost over the weekend.

Why it matters: That leaves less margin for a club opening Saturday with the score 0-0 and the series tied 1-1. It comes days after Jesus Luzardo went on the injured list with left shoulder inflammation, further testing the staff.

What to watch: Watch for Bowlan's throwing status and how Philadelphia Saturday's game has not started yet.
