TORONTO — Roy Halladay pitched his major league-leading ninth complete game to become the American League's second 20-game winner and the Toronto Blue Jays beat the New York Yankees 8-2 tonight.

Vernon Wells homered and drove in four runs as Toronto snapped the Yankees' seven-game winning streak.

Halladay (20-11) improved to 5-1 in six starts against the Yankees this season and posted his second career 20-win season. The right-hander went 22-7 with nine complete games in 2003, when he won the AL Cy Young award.

Halladay, who joined Cleveland's Cliff Lee as a 20-game winner, gave up two runs and six hits. He walked one and struck out five, giving him 206 for the season, a career-high.

Wells hit a two-run homer in the third and added a two-run single in the fourth as the Blue Jays closed out the home portion of their schedule with a 47-34 record.

Carl Pavano (4-2) allowed five runs and eight hits in 3 2-3 innings, his shortest outing since coming off the disabled list last month.
