Amid a conversation about Major League Baseball’s salary cap, a heated confrontation between Philadelphia Phillies’ Bryce Harper and MLB commissioner Rob Manfred ensued.

At some point, Harper told Manfred if he was there to talk about a salary cap, he could “get the (expletive) out” of the clubhouse.

Manfred and some owners have cited payroll disparity as one of baseball’s biggest problems, while at the same time MLB is working to address a revenue decline from regional sports networks.
