With one out in the third inning, Bradley was called out on strikes by home plate umpire Dan Bellino. Bradley dropped his bat and started to take off his batting gloves and then was tossed from the game by Bellino.
Mariners manager Don Wakamatsu claimed Bradley mistakenly thought his strikeout was the third out of the inning.
"I didn't understand it either,'' Wakamatsu told the Seattle Times. "And in all fairness to Milton, I think he thought it was three outs. He started taking his gloves off, his bat dropped and then he picked up his bat and walked off. And that's what I told the umpire. I didn't think that was called for, that I thought it was an overeaction on his [the umpire's] part.
"He said he [Bradley] couldn't do that. And I said 'Do what?' But like I said, I told him to go back at the end, look at his actions and tell me if he didn't think [Bradley] thought it was three outs right there. So, I just didn't think it was called for.''
Bradley forgot the outs after catching a fly ball against the Minnesota Twins last season when he was with the Chicago Cubs. He caught a fly ball off the bat of Joe Mauer for the second out of the inning and tossed the ball into the stands, allowing a runner to score from third base.
