Watch: Vegas' Jack Eichel scores hat-trick in return to Buffalo, taunts Sabres fans

Just over eight minutes later, Eichel struck again, corralling a pass from Chandler Stephenson before firing a quick wrister past Buffalo goaltender Eric Comrie for his second of the evening. 

Eichel put the exclamation point on his big night, scoring his third goal on an empty net with 7.6 left on the third-period clock. 

Eichel clapped back at Sabres' fans following a less-than-warm greeting upon his first visit back in March. 

Ahead of Thursday's contest, Eichel told ESPN's Kristen Shilton that he was "surprised" by the reception he received the first time around. 

"I'm just like anyone else; I'm a human being," Eichel said. "It was emotional for me like it was probably for them and maybe I was a little bit hurt and that's probably why I said things [after the game]."
