New York Yankees reliever Greg Weissert had a wild major league debut.

Cole Irvin allowed four hits over seven innings and the Oakland Athletics beat Houston Astros 4-2 for their first winning sweep in 32 series this season.

Billy McKinney homered and Daulton Jefferies and four relievers combined on a three-hitter to lead the Oakland Athletics past the Philadelphia Phillies 4-1 for Mark Kotsay's first win as a big league manager.
