The New York Yankees were for the first time since 2009 in the Philadelphia World Series and many were visitors in the stands of Citizens Bank Park.
This created a charged atmosphere in the Phillies' home park, which may have contributed to making the emotions high for both the players and the fans.
That boiled in the sixth inning of the Yankees' 4-2 victory when Phillies outfielder Rhys Hoskins seemed to swap a few words with a fan after he grazed but did not immediately run to first after the ball got off rebounded the catcher.
While it was unclear what exactly Hoskins said – and reports were unclear whether it was a Yankees fan or Phillies fan with whom Hoskins had his exchange – the stairs came back to scream at the crowd a bad look.
Hoskins was aware of this when he apologized after the game for his actions.
"Somebody said something in the stands that obviously triggered me" Hoskins told reporters after the game .
"I was pretty frustrated with the at-bat I just had, I mixed the mistake, I was trapped at the moment, should not happen, can not happen, but it did, and that's the way it is."
He added that "I was wrong".
