In the 12th inning of Thursday's win over Cincinnati, Werth collided with a fan reaching over to catch a foul pop by Drew Stubbs along the right-field line. Television cameras caught Werth angrily shout at the fan, who appeared to disrupt a catchable ball.
Werth said he got caught up in the heat of the moment -- considering the game was tied at 3 at the time -- and the catch would have ended the inning.
"There's been some backlash, I think," Werth said. "In the heat of the moment, and a situation that goes on, on the field, I'm definitely in a different mindset than I would be in a normal setting. I don't think I would've yelled at anybody liked that if that wasn't the case, with the game on the line."
