Robles, who was hit by a pitch three times in his previous four games with Tacoma, took some steps toward the mound while yelling at the pitcher but was held back by McCarthy and Las Vegas teammates.
After going into the dugout, Robles threw a box of snacks toward the field before heading to the clubhouse.
He took to social media later to apologize for letting his frustration get the best of him.
“Coming off a long rehab and being away from the game for most of the season has been physically and mentally challenging,” Robles said in his Instagram story. “Adding to that, the recent passing of my mother has been incredibly hard, and I’ve been doing my best to hold it together. That’s not an excuse, but some context I feel you deserve to understand where I’m coming from.”
He added, “Getting hit 5 times in 15 at-bats added to that pressure, and I reacted in a way I’m not proud of. This game means the world to me, and so do the people who play it. I respect every one of you, not just as a player, but as a teammate and competitor.”
Robles is rehabbing a dislocated left shoulder he suffered in April.
