Den Dekker, starting in left field for the first time this season in the majors, went 2-for-5 in the Mets' 7-6 loss to the Phillies on Sunday. Den Dekker, called up Friday night, hit .354/.416/.571 at Triple-A Las Vegas against right-handed pitching, against whom he will see most of his action with Eric Campbell (mainly) and Eric Young Jr. playing against lefties.
