The New York Mets purchased the contract of pitcher Chris Young from Triple-A Buffalo and activated pitcher Miguel Batista from the 15-day disabled list on Tuesday.
Young underwent surgery to repair a tear in the anterior capsule of his right shoulder on May 16 of last year. In four starts with the Mets last season he posted a 1.88 earned run average.
In four minor league starts this season Young went 1-0 with a 2.35 ERA between Single-A St. Lucie and Buffalo.
Batista went 1-1 with a 3.95 ERA in 13 games ,including four starts, for the Mets this year. The 41-year-old suffered a lowered back strain that forced him to the DL on May 20.
To make room on the roster the Mets placed pitcher Ramon Ramirez on the 15-day disabled list, retroactive to May 31, and designated pitcher Jack Egbert for assignment.
Ramirez went 2-1 with a 4.78 ERA in 22 games this season.
Egbert appeared in one game for the Mets, in which he retired the only two hitters he faced.
The team also announced that pitcher Jonathon Niese was examined in New York on Monday for an accelerated heartbeat, a condition he experienced on Sunday and has experienced on other occasions throughout his career. According to the Mets, Niese will undergo a minimally invasive procedure, most likely in the off season, to correct the condition. The procedure will not prohibit him from pitching.
