So you’re in the starting lineup for the A’s, first inning, you’re getting loose in the on-deck circle, and — wait a minute, you’re out of the game? That happened to Mark Canha in Tuesday night’s game against Seattle, and the way he reacted said a lot about the A’s. Certain episodes make it clear that it’s all about the team. Only two batters had come to the plate when Jed Lowrie stepped in against Seattle left-hander James Paxton in the first inning and lined a shot that struck Paxton on his pitching arm. Paxton, later placed on the disabled list with a forearm contusion, immediately left the game and was replaced by right-hander Felix Hernandez.
