Mat Fraser won 17.4 after Travis Mayer was penalized following video review. And now this week, Fraser sits atop the worldwide leaderboard once again with the best time on 17.5.

Take a look at Fraser’s video below as he blazes through the thruster / double-under couplet in 6:24. After watching the video, the reps look legit and we would expect it to stand.

And with it, Fraser is the winner of the 2017 CrossFit Open.
