Auger-Aliassime swept aside from the start!

Things aren't going according to plan for the top seeds at the start of the US Open.

While some of them got their tournament off to a perfect start, others, such as Holger Rune, Alexander Bublik and Alejandro Tabilo, failed to get off to a good start, bowing out in the first round.

On Tuesday, it was Felix Auger-Aliassime who stumbled. Faced with one of the circuit's rising stars, 18-year-old Jakub Mensik, ranked 65th in the world, the Canadian was unable to hold off an overexcited Czech with masterful tennis.

Winning in just over 2 hours (6-2, 6-4, 6-2), Mensik made his mark and will face Schoolkate, ranked 193rd, in the second round.
