As Rios was leaving a fundraising gala for the Jays Care Foundation, he got into a brief shouting match with a fan who critcized Rios for his recent performance on the field. The incident was captured on video and posted on YouTube, and then circulated on various Web sites.
Rios issued an apology before Friday night's game against the Royals.
"I just want to apologize for the situation that happened yesterday at the gala," Rios said. "I just want to apologize to my fans, to the team, to my teammates, because it was something that I should've never done and it was just a bad reaction on my side."
The altercation happened after a heartbreaking loss to the Angels, in which the Jays clawed their way back from a three-run deficit to tie the game in the eighth, before the Angels scored the go-ahead run in the top of the ninth, sending the Jays to a 6-5 loss. It was an especially rough game for Rios, who struck out in all five of his at-bats.
"It was a long day [Thursday]," Rios said Friday. "I couldn't help the team win, and it was just bad. ... I guess I just lost my cool in that situation, and it was bad.
"It's not the person that I am. Like I said before, I just lost my cool."
