With the platoon of Nick Evans and Daniel Murphy in left and Fernando Tatis in right, Church is without a starting spot. If Church can return before September 1, one of Evans or Murphy will be sent packing for a few days before they're called up when the rosters expand.
This would leave him as a spot starter and a pinch hitter. Church is 1-6 this season in PH chances, striking out twice.
I think Church, if he can come back healthy, will be the key to the postseason for the Mets.
