NEW YORK -- The Mets called up right-handed reliever Manny Acosta from Triple-A Buffalo on Tuesday in response to the heavy workload manager Terry Collins has been forced to place on his bullpen this week.
With three-inning efforts from starters Johan Santana and Miguel Batista on Friday and Saturday, and a 12-inning game on Sunday, New York's relievers had to work 17 innings during their three game series against the Dodgers. Monday's 10-inning series opener against Washington didn't help the situation.
"We've got an issue, and we need help," Collins said. "We have to nail some fresh arms down there so we don't kill guys."
Acosta, 31, was designated for assignment on May 29 after starting the year 1-2 with an 11.86 ERA in 22 innings. In 28 innings with Buffalo since the demotion, Acosta is 0-1 with a 2.25 ERA and 25 strikeouts. He threw 21 pitches over two innings of relief in a Minor League appearance on Monday, but Collins said the right-hander was still be available out of the bullpen on Tuesday.
"He's pitching very well," Collins said. "He's had, I think, only a couple bad outings in Buffalo, but [Buffalo manager] Wally [Backman] told me 'We all see that plus stuff.' When he keeps it down and pitches come in like he's supposed to, he's very, very good."
Lucas Duda and right-hander Pedro Beato were optioned to Buffalo on Tuesday to make room on the Major League roster for Acosta and top-prospect Matt Harvey.
