Mets' Dan Warthen back at work after being hospitalized for rapid heartbeat

ATLANTA -- New York Mets pitching coach Dan Warthen was back at work Friday after being released from a local Atlanta hospital. Warthen had "a racing heart that corrected itself," the team announced.

Warthen was admitted after experiencing a rapid heartbeat on Thursday and spent one night in the hospital. Bullpen coach Ricky Bones filled in as pitching coach during the series opener against the Atlanta Braves.

Warthen, 62, was at Turner Field before Thursday's 7-2 win over the Braves when the decision was made to send him for medical attention.

"I just got a text from him, and he was eating cake, so he couldn't be that bad," Collins said after Thursday's game. "We certainly will keep an eye on him."

Warthen has served as Mets pitching coach since June 17, 2008, and oversees a pitching staff that has the third-best ERA in the majors this season.

He spent parts of four seasons in the majors with the Montreal Expos, Philadelphia Phillies and Houston Astros.
