The pair of friends both outclassed compatriots Thursday in the Abierto Mexicano Telcel quarterfinals.

The American teamed up with countryman Mackenzie McDonald to upset the No. 4 seeds Juan Sebastian Cabal and Robert Farah Wednesday night.

Next up for the second seed is another countryman in J.J. Wolf, who found his way past Radu Albot 6-3, 7-6 (5).

Mackenzie McDonald also advanced, setting up a second-round meeting with No. 2 seed Frances Tiafoe.

Led by Tommy Paul and also featuring three rookies, the heavily-favored U.S. Davis Cup team completed a sweep of Uzbekistan in the qualifying round.

Both Americans posted straight-set victories Friday in Tashkent.

Tiafoe, McDonald, Korda, Brooksby, Paul, Shelton, Wolf and Mmoh have represented their country admirably—and in a variety of successful ways.

Plus, thoughts on the never-a-dull-moment Danielle Collins experience.

The 22-time major title holder came up limping late in the second set, but played in on an eventual 6-4, 6-4, 7-5 second-round defeat Wednesday on Rod Laver Arena.

The USTA announced the change as part of a news release that began by listing the members of the American roster that included doubles specialist Rajeev Ram alongside Tommy Paul and Jenson Brooksby.
