According to Mets manager Terry Collins, the 62-year-old Warthen will not be present at the ballpark for Friday's game, but Collins does not expect his pitching coach to be away from the team for too long.
“I just got a text from him, and he was eating cake, so he couldn't be that bad,” Collins said after the Mets' 7–2 win on Thursday night. “We certainly will keep an eye on him.”
Bullpen coach Ricky Bones took over for Warthen on Thursday, and will continue to do so as long as he remains out of commission.
Warthen has been New York's pitching coach for eight seasons, and had previously coached for the Pirates, Mariners, Padres, Tigers and Dodgers.
He spent four Major League seasons as a pitcher in the 1970s with the Expos, Phillies and Astros.
Under Warthen's tutelage, the Mets rank in the top three in ERA in Major League Baseball this season at 3.36, behind the Pirates and Cardinals.
