The Mets on Tuesday activated right-handers Chris Young and Miguel Batista from the disabled list. To make room, New York put righty Ramon Ramirez on the DL and designated Jack Egbert for assignment.
Young will take the hill on Tuesday night against the Nationals for the first time in more than a year after undergoing season-ending shoulder surgery on May 16 of last season. The 33-year-old was 1-0 with a 1.88 ERA in his first four starts as a Met prior to the setback.
As for Batista, a strained lower back forced him to the DL on May 20 after he had opened the season 1-1 with a 3.95 ERA over 13 appearances (four starts). He made one rehab start at Double-A Binghamton, allowing five runs (four earned) over seven innings.
Ramirez's placement on the DL comes after he strained his right hamstring celebrating Johan Santana's no-hitter last Friday. The move is retroactive to Thursday. Ramirez is 2-1 with a 4.78 ERA and one save in 22 appearances.
The 29-year-old Egbert, meanwhile, appeared in just one game for the Mets, retiring the only two batters he faced in a May 28 contest against the Phillies.
The Mets also announced that pitcher Jonathon Niese was examined on Monday in New York for an accelerated heartbeat -- a condition he experienced on Sunday and on other occasions. Niese is cleared to pitch, though he will likely undergo a minimally invasive procedure to correct the condition this offseason.
