ATP roundup: Nick Kyrgios picks up three-set win in Houston opener

Nick Kyrgios of Australia used three sets to defeat American Mackenzie McDonald 4-6, 6-3, 6-4 Tuesday in the first round of the Fayez Sarofim & Co. U.S. Men's Clay Court Championship in Houston.

Playing as a wild card, Kyrgios earned his first win on clay since 2019. He most recently made a stellar run at the Miami Open but was fined $35,000 for unsportsmanlike behavior during his Round of 16 defeat.

American wild card J.J. Wolf knocked off countryman and eighth seed Jenson Brooksby 6-4, 6-4. Wolf dialed up four aces and won three of six break-point opportunities against Brooksby.

No. 7 seed Tommy Paul of the U.S. won when German opponent Peter Gojowczyk retired in the third set. Other winners Tuesday included Dutch qualifier Gijs Brouwer, Australian Jordan Thompson and Americans Steve Johnson, Mitchell Krueger and Sam Querrey.

Four night matches in Houston pitted Chilean fifth seed Cristian Garin against American Jack Sock; Uruguay's Pablo Cuevas against Australia's Max Purcell; American sixth seed Frances Tiafoe against countryman Marcos Giron; and American Christian Harrison against Chile's Alejandro Tabilo.
