The Mets are still in first place, but they came back to earth a little bit Monday with a 5-2 loss to the Pirates that snapped a six-game win streak. Despite finishing 6-1 on the trip to Washington and Pittsburgh, the loss raised some questions about Jerry Manuel’s club. In the notebook, reliever Duaner Sanchez’s rough outing raised some questions about the health of his shoulder. There are also items on Johan Santana, Ryan Church and Eddie Kunz.
