Caeleb Dressel has set another Olympic record in the semifinals of the 100-meter butterfly.

Minutes after Hungary’s Kristof Milak took down the mark in the first semifinal heat, Dressel went even faster with a time of 49.71 seconds in the second heat.

It was the third-fastest time in history and left Milak as the second-fastest qualifier at 50.31.

In the preliminaries, Dressel tied the former Olympic record of 50.39 set by Singapore’s Jospeh Schooling to win gold at the 2016 Rio Games.

Dressel will be a big favorite in Saturday morning’s final, though he could get pushed by Milak. The Hungarian already won the 200 fly with a dominating victory.
