Per Jon Morosi of FOXSports.com, the Mets have signed RHP Miguel Batista to a minor league deal. Batista was released by the Cardinals on 22 June, before which he had allowed nineteen walks to just sixteen strikeouts in 29.1 innings. He has never been much of a strikeout pitcher and his control isn't really good enough to make up for that shortcoming.
He has generally been good at keeping the ball on the ground and in the ballpark, but he turned 40 in February and wasn't much of a pitcher even before entering the twilight of his career. He had been a starting pitcher for most of that career but has logged a couple hundred innings out of the bullpen over the past few seasons with the Mariners (2009), Nationals (2010), and Cardinals (2011).
For the Mets, he adds a bit of rotation and relief depth which they might have to lean upon in the coming weeks if the frequently predicted trade-deadline exodus unfolds as expected.
