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.

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