The New York Mets will shut down Jacob deGrom before his final start.

According to a source, the club has placed an innings cap on the 26-year-old right-hander.

DeGrom had been lined up to face the Houston Astros on Saturday at Citi Field.

The rookie has logged 140 1/3 innings in the majors this season, and 178 2/3 innings overall when his Triple-A work is included. That's already a jump of 31 innings from his 2013 total.
