No. 2 Carlos Alcaraz def. No. 32 Luciano Darderi, 6-2, 6-4, 6-0

Adrian Mannarino def. No. 6 Ben Shelton, 3-6, 6-3, 4-6, 6-4 (retired)

No. 20 Jiri Lehecka def. Raphael Collignon, 6-4, 6-4, 6-4

Shelton’s retirement from the tournament came after the end of the fourth set against Mannarino.

Prior to the retirement, Shelton put on a show inside Louis Armstrong Stadium against the French lefty.

Shelton’s departure means that Carlos Alcaraz can likely cruise into the semifinals.

The second-seeded Spaniard has two unseeded players and No. 20 seed Jiri Lehecka left in his quarter of the draw.

Alcaraz looked strong once again on Friday with a straight-set triumph over No. 32 seed Luciano Darderi.

Novak Djokovic and Taylor Fritz, who both play on Friday night, are on a collision course to meet in the other quarter in the bottom half of the men’s singles draw.
