SAN FRANCISCO — The Friday night confrontation between Aroldis Chapman and the Giants’ Wilmer Flores — who had to be separated as the dugouts began to clear — following the final out of the Sox’ win apparently stemmed from Flores’s behavior in the batter’s box.

Aroldis Chapman and Wilmer Flores exchanged words for a few seconds at the end of Friday's Red Sox-Giants game, causing the benches to clear.

The final out of the Red Sox' 7-5 victory Friday night led to a mysterious dispute between one Boston reliever and a Giants player.
