The Mets' injury woes continue. Their latest setback came in the form of reliable late-inning reliever Ryota Igarashi, who was placed on the 15-day disabled list with a left hamstring injury he sustained during Tuesday night's game.

Igarashi, who had an MRI at the Hospital for Special Surgery on Wednesday, "will progress to baseball activities as tolerated," the club said in a news release.

In order to fill his spot on the 25-man roster, the Mets recalled right-hander Manny Acosta from Triple-A Buffalo. Acosta will be available for Wednesday night's game against the Cubs at Citi Field.

Igarash, a veteran of Japanese professional baseball, had a 1.35 ERA through 6 2/3 innings in his first year in the Major Leagues. The 30-year-old right-hander strained his left hamstring in the eighth inning of the Mets' 4-0 win over Chicago when he squatted to field a bunt. Igarashi then faced two additional batters, but he was removed after a visit to the mound by the trainer.

The 28-year-old Acosta, who was claimed off waivers from the Braves in late March, appeared in five games for the Bisons in 2010, posting a 2.16 ERA in 8 1/3 innings.
