Mat Fraser returns to defend his title at Regionals, but veteran Games athlete Albert-Dominic Larouche is returning to the fray to claim a spot to Carson. Here’s who to watch in the East:

The heir apparent to the Frone, Mat Fraser has had two incredibly successful and equally frustrating years at the Games with two silver medal finishes in a row. "I hate second place" is all you need to know about Fraser. The man is gunning for the top of the podium and everyone else in the East is in his way.

After missing last year's Games by just a handful of points, Tremblay was on the 2015 Games Demo team and wanted nothing more than to be on the field competing with the rest of the athletes. That fire will drive him to great things this year.

Placing 2nd in the East Regional and 11th at the CrossFit Games shows that Alex Vigneault is the real deal. Look for him to challenge Fraser for the top spot in the East.

Boomsauce Tyminski has been a Games athlete for a long time and his consistency in training and willingness to suffer set him apart from other competitors. Lucky for him, this year's events play to some of his biggest strengths, so he's set for some big performances.

ADL took the 2015 Games Season off, but didn't rest up the whole time. With some big event wins under his belt in the off-season, Larouche is looking to return to defend his first place finish from the 2014 Canada East regional.

Austin Malleolo came onto the scene in 2010 and has been around ever since. His long arms aren't going to help him on any event other than Event 5, but he's got fitness and a history of being clutch.

Spencer Hendel

Easily the tallest CrossFit Games athlete, Hendel qualified for the 2015 Games after missing qualification in 2014. Coming back from a loss like that to qualify in a harder competition is impressive and Hendel is committed to attacking his weaknesses regularly.
