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. The person spoke to the AP on condition of anonymity because of the sensitivity of the situation. Phillies slugger Nick Castellanos previously confirmed some details from the meeting in interviews with The Bandwagon and ESPN. Manfred met with the Phillies and Red Sox during their series last week in Philadelphia. The session with the Phillies lasted more than an hour.
