Barger went 2-for-4 with a solo homer in a 5-4 win over the Angels on Friday.
Joey Loperfido and Barger jumped on Roansy Contreras in the ninth inning, going back-to-back to end the game. It was Barger's first career walk-off homer and the second time in Blue Jays history that rookies went back-to-back in the same game. Barger also became the 10th rookie in team history to hit a walk-off home run. He's started six of the Blue Jays' last seven games, with two long balls in that span.
