[...] Peavy set out to throw 100 pitches and seven innings, which is exactly what he did. He threw 71 for strikes. In a rocky third inning, he ­allowed five runs and four hits, including a home run to Ryan ­Strieby. He breezed through the other six innings, each three-up, three-down, and finished with five strikeouts and one walk. He struck out the last two batters he faced on seven pitches. According to the stadium radar gun, Peavy’s fastest pitch was 93 mph. Most of his fastballs were in the upper 80s.
