Joba Chamberlain?s fastballs reached 96 miles an hour against the Tigers, and he pitched comfortably at 92 to 94 while allowing one run and three hits, with three walks and six strikeouts over seven innings. Until Wednesday's start, there had been a growing sentiment that Chamberlain would be better suited for late-inning relief work. Chamberlain is now 4-1 with a 2.85 earned run average as a starter, with more strikeouts than innings pitched. ?He?s got such good stuff that I?m sure we?ll debate this forever,? Manager Joe Girardi said. ?But that?s what we think he can do.?
