"They happen all the time. Sometimes people see it more than others, but things happen," Girardi said. "You put 40 grown men in a room for 190 straight days, things happen. There's intensity, there's emotion.
"I know as a player there's been times that I've said things and wish, 'Man, I probably could have done that different.' But to me it's all about your heart, where your heart really is. Tex displays a lot of intensity every day he plays, and we understand that."
Espada apologized to Teixeira for sending him and said the mistake was his own. Teixeira said after Monday's game that he was shocked to have to slide in hopes of avoiding the tag from catcher Robinson Chirinos.
"Yeah, for a lot of reasons. I can get hurt," Teixeira said. "I'm not expecting a play at the plate. That's a big run. There are a lot of reasons why that can't happen."
Girardi said that the incident was discussed after Monday's game and is considered to be "a non-factor" in the Yankees' clubhouse.
"The one thing that we want from our players is intensity," Girardi said. "I think Joe Espada has done a tremendous job, coaching third, coaching our infield. As a player, there are times that I made incorrect reads as a baserunner.
"As a manager sometimes or as a player, I've said things that I wish I'd maybe stated a little bit different. Everything's OK. We talked about it, we move on and we learn from it. Things are good."
