 Biographical Information
Mather was called up by the Cardinals in late May of 2008 and played quite a bit in the outfield from that point on, getting into 54 games and hitting 8 home runs in 133 at-bats. Unfortunately, his season ended early when he broke his left wrist while attempting to check his swing in a game against the Arizona Diamondbacks on September 1; he had hit a home run earlier in that game. The injury, similar to one suffered by Ryan Zimmerman a year earlier, required corrective surgery.
On April 17, 2010, Mather was pressed into action as a pitcher after the Cardinals had run out of pitchers in a marathon game against the New York Mets. Mather took the mound in the 19th inning of a scoreless game, succeeding infielder Felipe Lopez who had pitched a scoreless 18th inning, with the game still scoreless. He gave up a run to the Mets on a sacrifice fly by Jeff Francoeur, but the Cardinals tied the game again in the bottom of the inning against Francisco Rodriguez. So Mather came back to pitch the 20th, and gave up another run, on another sac fly, this time by Jose Reyes, and was saddled with the 2-1 loss.
Mather became a manager with the Missoula Osprey in 2015.
