Den Dekker, riding a five-game hitting streak, during which he has gone 9-for-19, is hitting second Friday against the Reds. Den Dekker was moved up in the order while Curtis Granderson was moved down and is hitting sixth. The Mets are giving den Dekker every chance to show he should be penciled into the 25-man roster heading into next spring, and so far, he has responded well to the challenge since his call up August 8.
