Last night’s beating has left the relievers in need of relief, so the Mets today recalled Jeremy Hefner and sent down infielder Jordany Valdespin. Hefner appeared earlier this year wearing uniform No. 53 and backing up starter Miguel Batista when Batista was hammered by the San Francisco Giants. The prospect of the Blue Jays bats unloading on Batista — despite his best start last time out — suggests the Mets are making a prudent move.
