HOUSTON (AP) Jack Sock won the U.S. Men's Clay Court Championships on Sunday for his first ATP World Tour title, beating eighth-seeded Sam Querrey 7-6 (7), 7-6 (2) in an all-American final.
The 22-year-old Sock saved three set points in the first tiebreaker in the rain-delayed match and quickly answered a break by Querrey in the second set to get the match back on serve.
Sock became the sixth American to win the country's only men's clay-court tournament. He will climb to a career-high 36th in the ATP ranking.
Sock, the Wimbledon doubles champion with Vasek Pospisil, was playing his first ATP singles final in only his third tournament of the season. He underwent surgery to repair a torn muscle in his hip in December and didn't return until Indian Wells last month.
