Matt Harvey has enjoyed his best month of the season in August, but trouble may be coming for the New York Mets.

Harvey, who is working his way back from Tommy John surgery, allowed just one run in four starts. He struck out 24 and walked just two while allowing 15 hits in 27 innings.

The issue for Harvey and the Mets is that he's nearing the innings limit (180) prescribed by surgeons. With four weeks remaining in the regular season and the playoffs looming, Harvey is at 160 innings.
