Simon struck out four and walked three while holding the Mariners to five runs on eight hits over 5.2 innings Monday night in a winning effort. On a night when Simon struggled, he was bested by Hisashi Iwakuma and the Seattle bullpen, while the latter offered a late buffer to put Simon in line for the victory as the Detroit offense scratched out seven runs following Iwakuma's departure. Simon is scheduled to finish the first half Saturday in Minnesota against the Twins.
