With one out and a man on third, Ethier looked at a fastball that appeared inside. Home-plate umpire Mark Carlson rung up Ethier, who immediately voiced his displeasure.
But Ethier headed to the dugout, appearing to get off scot-free, until he turned around and barked once more at Carlson. That was enough to get him tossed for the second time in his career. (The first came on Aug. 26, 2010.)
Ethier's ejection brought Mattingly out of the dugout to argue with Carlson for a minute or two, and he was ejected for the first time this season and the fourth time as manager.
"In that situation there, I just thought it was a close call," Ethier said. "Me and Donnie talked afterwards, and it's probably not the best situation for me to get thrown out right there, especially with Matt [Kemp] coming out of the game [with an injury] and us being short-handed a player."
Ethier finished 0-for-3, but the strikeout didn't harm the Dodgers as A.J. Ellis hit a three-run home run later in the frame to give them an 8-4 lead.
The Dodgers, playing without Kemp, who exited after he aggravated a left hamstring strain in the third inning, put Scott Van Slyke in right field.
