The play in question transpired in the sixth inning of New York's 4-2 loss to the A's on Thursday, when Robinson Cano hit a foul ball and Rodriguez had to return to first base. Rodriguez decided to cut across the infield and, in doing so, set foot across the top of the mound.
"I was tired," said A-Rod, who guessed that he might have done the same thing a few dozen times in Major League games. "It's really not that big of a deal."
Braden certainly took exception, calling out Rodriguez after the play and also after the inning before venting to reporters. Rodriguez returned a dismissive wave to Braden's shouts and, in the bottom half of the eventful inning, started the Yankees' first triple play since 1968.
"I think it's competitive spirit -- boys being boys," Yankees manager Joe Girardi said. "As far as what Dallas said, I'm concerned about how my player reacts. I'm not concerned about how other players react. You move on.
"I don't think Alex was doing anything malicious or trying to send a message," Girardi continued. "I think he just happened to run back to first base. The shortest distance between two points is a straight line."
In his postgame sessions with reporters from Oakland and New York, Braden suggested that Rodriguez "should probably take a note from his captain over there and realize you don't cross the pitcher's mound in between an inning or during the game," a reference to Derek Jeter.
But Jeter seemed to have A-Rod's back, and furthermore, was amused by Braden's claims.
"It never crossed my mind," Jeter said. "I've never heard that before. If you asked me that question yesterday before the game, it's one of those things I'd never think of."
Jeter said that Braden's statements were "out there" and pointed out that CC Sabathia had spent plenty of time on the Coliseum mound that afternoon as well.
"It isn't like [Braden] brought it from home, you know what I mean?" Jeter said.
The Yankees' Mark Teixeira said that he also didn't believe Rodriguez had fractured any of baseball's unwritten codes.
"I'm sure it happens hundreds of times a year, I would assume," Teixeira said. "It's such a non-issue that, in eight years, I've never heard about it or heard anyone talk about it.
"Alex handled it with perfect class. He handled it great. He could have been more upset. He just shrugged it off because it was comical. We had fun with it once we heard his comments. We've been laughing since."
Rodriguez was right there with them, chuckling to himself between chomps of bubble gum as he headed for batting practice.
"This is not even entertaining," Rodriguez said. "I think it's funny that you guys are thinking it's funny that I think it's funny."
