But why? Are we worried his ERA will be above 7 like the guys who are pitching in his place? I guess this is standard practice, but it seems like a good time to throw out the convetional wisdom.
Fill in starters have combined for a grand total of 1 good start, and that was on a drizzly cold day with the wind blowing in. And it wasn't that good of a start. 6 innings, 2 runs.
