OAKLAND — With a sold-out crowd on their feet at the Oakland Coliseum on Thursday afternoon chanting “Let’s Go Oakland” at the top of their lungs and Texas Rangers outfielder Travis Jankowski at the plate facing a 1-2 count, Athletics All-Star closer Mason Miller unloaded a 103 mph fastball. Jankowski made weak contact, rolling over to third baseman Max Schuemann, who fired the ball across the diamond to first baseman Tyler Soderstrom to not only end the game by a 3-2 score, but end the team’s 57-year tenure in “The Town.”
