Well, he didn't walk anyone and only one of those hits went for extra bases. It looks like several of the "hits" never left the infield. The defense was poor making four errors that game (two behind Stewart), although they did turn a double-play that Stewart coaxed and threw a runner out at home. My take is that he stopped the bleeding and worked out of jams early in a game where his BABIP luck was against him. Six innings, K per inning, no walks, no homers, two earned runs, .500 BABIP against (including 7/14 on ground balls) .... Sounds like a quality start to me It may be that your expectations are perverted.
