If your only option is Pelfrey for game 163, I think you have to go with a bullpen game at that point as it's your best shot. 3 innings from May, 2 innings from Tonkin, 2, innings from Fien/Cotts, 1 inning from Perkins, 1 inning from Jepsen. If the option is a 3 man rotation in the playoffs or a 4 with Pelf, you have to go with a 3 man rotation. Since June he has 19 starts, a 5.62 ERA, 1.65 WHIP, and opponents are batting .335/.381/.464 against him. (Which is pretty much the season splits for Francisco Lindor over this whole season, that means that Pelfrey makes every batter he faces look like Lindor at the dish) Not good, can't be trusted period, especially can't be trusted against good PLAYOFF teams. Stick him in the pen.
