Mike Trout hit two home runs, including a tiebreaking shot in the eighth inning, Kenley Jansen got his 29th save, and the Los Angeles Angels pushed the Houston Astros to the brink of playoff elimination with a 4-3 victory on Friday night. Trout snapped a 3-3 tie with a leadoff homer to right-center field off Astros reliever Bryan King (5-4) in the eighth. Jansen struck out the side in the ninth, winning a 10-pitch duel with Mauricio Dubón to end the game, for the 476th save of his career, moving the 37-year-old right-hander to within two saves of Lee Smith for third on baseball’s career list.
