Manny Acosta has a 10.53 ERA!

Last night in Toronto, Manny Acosta allowed five earned runs and walked four batters in only two innings of work.

In 17 games this season, Acosta is 1-2 with a 10.53 ERA, allowing 42 base-runners in only 19 2/3 innings.

Last night, Adam Rubin of ESPN New York said the Mets are expected to promote Jeremy Hefner from Triple-A Buffalo for today's game against the Blue Jays.

Hefner threw three scoreless innings of relief against the Giants last month at Citi Field.

Michael Baron: Acosta is killing this team. The fact he could be less effective than D.J. Carrasco is noteworthy in and of itself. Right now, he's doing nothing more than throwing the ball as hard as he can ' and when he does throw his slider, he has basically no break on it, and hitters do not miss it. He's got no game plan, no approach, and no mound presence. The sum total of those problems are a 10.53 ERA on his line.

At this stage, he is becoming increasingly more difficult to justify a roster spot. If the Mets promote Hefner from Triple-A Buffalo, I have to believe Acosta is the odd man out. They must find more consistency in that bullpen and figure out a way to bridge the gap to Chris Young (and maybe Matt Harvey later this year) in the rotation. Hefner might not be to savior, but he has thrown strikes with consistency at Triple-A and, right now, he might be the best answer the Mets have.
