From Adam Rubin of ESPN New York comes word that Mets left-hander Jon Niese had to be lifted prematurely from his Saturday afternoon matchup with the Rangers due to a “rapid heartbeat.”
Niese struck out seven batters and allowed only two runs over 5 2/3 quality innings against a dangerous Rangers lineup. But it was a steamy day in north Texas and the heat almost certainly played a factor in the lefty’s irregular heartbeat.
Mets manager Terry Collins told reporters in his postgame press conference Saturday that the matter is not considered serious and Niese was later spotted smiling while walking around the visiting clubhouse. It’s feasible that the 24-year-old southpaw, who has a solid 3.70 ERA in 97 1/3 frames this season, won’t need to miss any more action.
UPDATE, 7:55 PM: According to Andy McCullough of the Newark Star-Ledger, Niese said he is “unalarmed” by the rapid heartbeat but is likely to undergo further testing next week in Detroit.
