ATP No. 83 Thiago Agustin Tirante of Argentina rallied from a first-set disappointment on Friday to upset top-seeded Ben Shelton at the U.S. Men's Clay Court Championship in Houston.
Shelton pulled out a 7-6 (5) win in a hotly contested first set before Tirante rebounded to win the next two, 6-3 and 6-4. Tirante was a perfect 16-for-16 on service games won.
The loss continues a cold streak for Shelton, who hasn't advanced past the round of 16 since emerging with a victory over Taylor Fritz in the Dallas
Open championship on Feb. 15.
In other action on the clay in Houston, Argentina's Roman Andres Burruchaga downed third-seeded Learner Tien 7-5, 6-4 and Tommy Paul defeated Argentina's Tomas Martin Etcheverry 6-4, 6-2.
In the final match of the night, No. 2 Frances Tiafoe outlasted Australia's Alexei Popyrin in a 3-6, 6-4, 7-6 (6) win which took two hours and 47 minutes. He'll face Paul in an all-American semifinal while the two Argentinians will face off in the other.
