Jack Suwinski hit his third homer of the game in the ninth inning, giving the Pittsburgh Pirates a 4-3, walk-off victory over the San Francisco Giants on Sunday to avoid a three-game sweep. The rookie drove a slider from Tyler Rogers (0-3) to right for his second game-ending home run of the season after connecting for one June 4 against the Arizona Diamonbacks. Suwinski is the first Pirates rookie to hit three homers in a game since Andrew McCutchen on Aug. 1, 2009.
