Mets manager Terry Collins said Monday that pitcher Jacob deGrom is on an innings limit this season, The Star-Ledger reports. Collins also spoke about his plans to use a six-man rotation when Dillon Gee returns from the disabled list, saying that he told his pitchers it was to keep them fresh late in the year.

deGrom threw 178 1/3 innings last season, with a majority of them coming in the majors during his Rookie of the Year campaign. He's up to 55 2/3 innings this season through nine starts and owns a 2.75 ERA and 54:13 K:BB ratio.

The team is looking to limit the innings of deGrom, Matt Harvey and Noah Syndergaard in the event of a possible playoff run, MLB.com reports.

"The six-man rotation, at this point, is in large part to manage innings, manage appearances, manage pitches," general manager Sandy Alderson said "There is always the risk that guys are getting too much rest. But at the same time, we don't want to run out of innings for any of our starting pitchers at the end of the season."
