Brett Gardner hit the New York Yankees' 15,000th home run, lining a full-count pitch from Toronto's Drew Hutchison into the lower deck in the fifth inning Sunday.
The Yankees, citing research from the Elias Sports Bureau, said they became the first team to reach the milestone. The total starts in 1903, the first year the franchise started play in New York.
Mickey Mantle hit No. 5,000 on Aug. 8, 1954, at Detroit against Billy Hoeft, and Claudell Washington hit No. 10,000 on April 20, 1988, at Minnesota off Jeff Reardon.
Brian McCann's first-inning home run tied the score, and Gardner's put New York ahead 2-1.
