Alex Cora is 0 for 2 in arguing obstruction calls with umpire Alan Porter after the Boston Red Sox manager was ejected in the fifth inning of a 9-5 loss to the Los Angeles Angels, the second straight game in which Cora was tossed. Cora wasn’t around to see the Angels score four in the eighth to snap a 5-all tie, but he saw enough of Walker Buehler’s shaky start to acknowledge the veteran right-hander might be losing his grip on a rotation spot. Handed a 3-0 lead before he took the mound, Buehler walked four and hit two batters during a five-run first inning in which he threw 39 pitches. He finished with a career-high seven walks in four innings and has a 6.29 ERA in 13 starts.
