Watch: Marner scores his first career goal!

The Leaf rookies haven't wasted any time scoring their first career goals so far this season.

Tonight it was Mitch Marner who scored his first career goal. 

It started with him showing his great hands by reaching back and bringing the puck to his forehand before skating in one on one against the Boston defender. He then ripped a shot blocker side past Anton Khudobin.

Marner had a big celebration. He is a local boy from Markham who grew up a Leafs fan so you knew that one must have felt so good.

It will definitely be the first of many for him. Congrats Mitch!
