Doug Fister stifled Toronto over eight innings and Jhonny Peralta launched a pair of homers Sunday in the Detroit Tigers\' 4-1 win over the Blue Jays. Fister (5-7) won for the fourth time in five outings, striking out nine while hurling 71 of his 109 pitches for strikes. The right-hander worked around a pair of walks as the Tigers avoided a three-game sweep at the hands of the Blue Jays. Peralta\'s three-run shot in the second erased an early 1-0 deficit and the Detroit shortstop added a bases-empty clout in the ninth to supply all of the Tigers\' offense. Second-place Detroit came into the contest trailing the American League Central-leading Chicago White Sox by 2 1/2 games. Toronto\'s Brett Cecil (2-4) was tagged with the loss, surrendering three runs on four hits over 6 2/3 frames. Colby Rasmus drove in the Blue Jays\' only run.
