The Mets have placed closer Bobby Parnell on the 15-day DL with a herniated disk in his neck. The move is retroactive to July 31. Infielder Wilmer Flores has been recalled from Triple-A Las Vegas to fill the roster spot.
Parnell, 28, has not pitched in a week due to continued discomfort in his neck. He received a cortisone shot on Monday and is eligible to be activated off the DL next Thursday. It's unclear if he'll be ready by then. Manager Terry Collins indicated surgery was a possibility.
In 49 games before the injury, Parnell went 22 for 26 in save chances with a 2.16 ERA and 3.67 K/BB. He owns a 3.55 ERA in parts of six big-league seasons, though this is his first as the team's undisputed closer.
Right-hander and former Mariners closer David Aardsma figures to take over ninth-inning duties during Parnell's absence. He has a 3.70 ERA and 2.20 K/BB in 24 1/3 innings for New York this season. Aardsma saved 69 games for the Mariners from 2009-10, but made just one appearance from 2011-12 due to hip and Tommy John surgeries.
Flores, 22, hit .321/.357/.531 with 15 home runs in 107 games with Triple-A Las Vegas before being called up. Baseball America thrice ranked him as one of the game's top 100 prospects (2009-11), and before they season they considered him the team's sixth-best prospect.
Although he has played all over the infield in his minor-league career, Flores has played primarily second base this summer. He could play third base in place of the injured David Wright, or he could play second with Daniel Murphy moving over to third.
