Jordany Valdespin’s unofficial position as spring training began was “left out,” but his performance in camp is forcing the Mets to reconsider.

If Valdespin continues producing, he almost certainly will earn a spot on the opening day roster, a team official said yesterday.

“We might need that bat,” the official said.

That was before Valdespin delivered a go-ahead RBI single in the eighth inning of the Mets’ 3-0 exhibition victory over the Cardinals yesterday at Roger Dean Stadium.

Valdespin is 9-for-25 (.360) with two homers and five RBIs this spring, while shuffling between second base and the outfield. If Valdespin makes the team, it would likely be at the expense of Kirk Nieuwenhuis or Mike Baxter, both of whom are struggling at the plate.

Nieuwenhuis is 1-for-18 (.056) and has recently been sidelined with a bone bruise in his left knee. Baxter has gone 2-for-20 (.100). So there figures to be at least one job competition — the bullpen battle notwithstanding — over the final 2 1/2 weeks of camp.
