Removed from the rotation Aug. 2, Zito made four relief appearances before being named to replace the injured Chad Gaudin to start Wednesday against Boston. Zito pitched a scoreless first inning but was victimized by subpar defense and Will Middlebrooks' second-inning home run. The left-hander ultimately allowed six runs and seven hits in 3 2/3 innings.
Overall, Zito is 4-9 with a 5.63 ERA in 26 appearances, including 22 starts.
