It's been widely known for some time that the Tigers' acquisition of Doug Fister before the 2011 Trade Deadline turned out to be a good move. His month of September, and an accolade that came with it, certainly verifies that fact.

Fister was named the American League Pitcher of the Month for the first time on Thursday after posting a 5-0 record and a league-leading 0.53 ERA over the course of September. He racked up 34 strikeouts and just three walks in 34 innings over five appearances (four starts).

Before Fister was traded to the Tigers from the Mariners on July 30, he was 3-12 with a 3.33 ERA in 146 innings and 21 starts. Since his Aug. 3 debut with the Tigers, he is a remarkable 8-1 with a 1.79 ERA. That ERA was the fourth-best in the Majors for that span.

Up against Major League leaders with at least 23 innings pitched, Fister was tops in ERA and opponents' batting average (.127) and was tied for first with Florida's Javier Vazquez in wins. Vazquez was named the National League Pitcher of the Month.

Fister started the month on Sept. 5 against the Indians when he allowed two runs (one earned) on four hits while posting a career-best 13 strikeouts in eight innings in Detroit's 4-2 win at Progressive Field.

In his next start, he kept the Twins scoreless for seven frames while striking out five and walking two in a 2-1 victory, helping the Tigers to their ninth straight win and a sweep of the division rivals.

Fister was also on the hill for Detroit's AL Central-clinching win on Sept. 16 against the A's, when he allowed just one run on three hits in the 3-1 win.
