CHICAGO (AP) — Baseball Commissioner Rob Manfred and Philadelphia Phillies star Bryce Harper had a spirited exchange during a question-and-answer session between the commissioner and the team, according to a person with direct knowledge of the conversation.

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.
