Mets’ Jacob deGrom has arm inflammation, out at least 2 more weeks

NEW YORK — Mets ace Jacob deGrom is being shut down for at two more weeks because of inflammation in his right arm, making it unlikely he’ll rejoin the NL East leaders before September.

Acting New York general manager Zack Scott said deGrom was diagnosed with inflammation following a bullpen session.

Mets manager Luis Rojas said deGrom was clocked in the high 90s near the end of his session. But Rojas said the two-time NL Cy Young Award winner didn’t throw Friday, a deviation from deGrom’s normal healthy routine of throwing every day.

DeGrom is 7-2 with 1.08 ERA in 15 starts, striking out 146 in 92 innings. He hasn’t pitched since July 7, when he allowed two runs and struck out 10 over seven innings against Milwaukee.

DeGrom was put on the injured list July 18 with right forearm tightness.

It’s the second IL stint of the season for deGrom, who missed two weeks in May with a sore right side, but the fifth known injury he’s battled. DeGrom exited consecutive starts in May with a sore right flexor and a sore shoulder.

With deGrom sidelined, the Mets’ rotation will be led by Marcus Stroman, the only starter to take every scheduled turn this season, and Tylor Megill, whose 2.04 ERA is the second-lowest in team history for a rookie through seven starts behind Nolan Ryan.

Taijuan Walker earned his first All-Star Game berth but has a 15.43 ERA in the second half. Carlos Carrasco, who suffered a torn right hamstring in spring training, made his New York debut Friday night and Rich Hill, acquired from the Tampa Bay Rays on July 23, is slated to make his second start for his new club Saturday.
