Wagner had a good first half of the season in 2007. He was successful in 17 out of 18 save chances, and his ERA was 1.94. July was his best month, when he recorded eight saves in eight chances; did not allow a run scored; and he won the D.H.L. "Delivery Man of the Month" Award. During that month, Wagner's ERA was 0.00, he gave up two hits, and he pitched enough innings to be equivalent to a complete game pitched. His performance earned him a slot on the National League All-Star Team.
