Auston Matthews' Mom

Auston Matthews became the first player to score four goals in his NHL debut Wednesday, and his mom's reactions were priceless. Here's Ema Matthews after Auston recorded his third goal for a hat trick:

Drafted No. 1 overall by the Toronto Maple Leafs in June, Matthews scored twice in the first period and twice in the second.

"Those were tears of joy," Ema Matthews said after the Maple Leafs' 5-4 overtime loss in Ottawa. "I feel very excited. This is what Auston has been dreaming since he was 6."

Matthews, a 6-foot-3 center from Scottsdale, Arizona, is now 19. He took the unconventional route of playing professionally in Europe in the season leading up to the draft. He had 24 goals and 22 assists in 36 games for the ZSC Lions in Switzerland.
