Stras has pitched 110.1 innings, leaving him with 69.2 left, and with 19 starts he's averaging just over 5.2 innings a game, so with the 180 inning pitch count he's on pace for twelve more games.

Leaving him one scheduled start short of the end of the season which would be on 9/29. Lots of time between now and then, but if Stras can pitch right up to the end of the regular season I see no chance that Davey doesn't have him start at least a couple games in the playoffs. (Unless of course Wang is back to his old self by then.)
