Pinch hitter Dioner Navarro had a game-ending sacrifice fly in the 11th inning, lifting the Chicago Cubs to a 4-3 victory over the Pittsburgh Pirates on Sunday.
Anthony Rizzo sparked the winning rally with a leadoff single.
He advanced on Alfonso Soriano's single and went to third when Pirates catcher Russell Martin threw the ball into center field while trying to pick Rizzo off second.
Luis Valbuena was walked intentionally before Navarro's fly ball to right off Bryan Morris (4-3) gave the Cubs their seventh win in the last 11 games.
Matt Guerrier (3-4) pitched two scoreless innings for the win.
