Hunter Greene will return to the Cincinnati Reds' rotation Wednesday night.
The right-hander will start against visiting Philadelphia after being out since June 4 with a strained right groin. The same injury sidelined Greene for two weeks in May.
Greene is 4-3 with a 2.72 ERA in 11 starts this season. The 26-year-old was selected to the All-Star Game last year for the first time.
In three rehab starts for Triple-A Louisville, Greene allowed 11 runs in 11 innings.
Cincinnati (61-57) entered Sunday 2½ games behind the New York Mets for the third wild-card spot in the National League.
