The Mets will activate Triple-A RHP Manny Acosta prior to Tuesday’s game against the Nationals.

The team has yet to announce a corresponding roster move. However, late Monday, Bob Klapisch of the Bergen Record (as well as other reporters) said Lucas Duda will be sent to Triple-A to make room on the roster.

Earlier this season with the Mets, Acosta was 1-2 with a 11.86 ERA in 19 appearances.

In his last 17 appearances for Triple-A Buffalo, Acosta has pitched to a 2.28 ERA with 25 strikeouts and four walks in 28 innings pitched.

However, the most interesting part of this will be the corresponding roster move. Lucas Duda was rumored earlier to be shipped out of town to Buffalo in order to make room for Matt Harvey, but survived when Pedro Beato was optioned to Triple-A Buffalo after last night’s game.

If it is Duda, it’s an interesting move by the Mets and somewhat inconsistent. Duda is struggling at the plate – as Ike Davis was and still does at times – but Davis remained on the roster to work out his issues. Granted, the run-producing numbers that Davis is putting up while still trying to regain his form isn’t there with Duda, it’s still an inconsistent message being sent by the team. But, perhaps as MetBlog’s Brian Erni said yesterday, getting Duda back to “strong approach” is the best option for Duda right now.
