Also in the American League, the Minnesota Twins saw off the Detroit Tigers 6-4 to give manager Ron Gardenhire his 900th career win, Jered Weaver pitched seven scoreless innings to help the Los Angeles Angels overcome the Indians 3-0 in Cleveland and the Seattle Mariners defeated the Baltimore Orioles 6-3.
