Bryce Harper told Rob Manfred to "get the f*** out of our clubhouse" if he wanted to talk about a salary cap, ESPN reported.

After Philadelphia Phillies star Bryce Harper got in the face of Major League Baseball commissioner Rob Manfred during a heated meeting last week, Mark DeRosa, a former big leaguer who now works for Manfred, said something some players took as a threat, according to four people who attended the meeting or were briefed on it.

That was evidenced last weekend, when commissioner Rob Manfred visited the Phillies clubhouse in an attempt to find common ground with the players. Instead, what happened was a heated argument between Manfred and the Phillies players, in which star Bryce Harper told Manfred to "get the f--- out of our clubhouse," according to ESPN's Jeff Passan.
