It was a bad news-good day for Jerry Manuel and the Mets on Tuesday. After learning Billy Wagner could miss the rest of the season because of a swollen left elbow, the first-place Amazin’s took advantage of someone else’s bullpen woes to pound out a 7-3 win over the Braves. In the notebook, John Maine has been ruled out as a bullpen candidate because of recent arm soreness. There are also items on Luis Ayala, Luis Castillo and Ryan Church.
