Sixth-seeded Ben Shelton won all eight break points in the match and emerged with a 7-5, 6-7 (3), 6-4 upset of top-seeded Russian Andrey Rublev on Friday in the quarterfinals of the Swiss Indoors Basel.

Shelton saved all six break points he faced and converted each of his two break chances — one to end the first set, the other for a 5-4 lead in the third set. He closed out the match with a service-game win at love.

Next up for Shelton is a semifinal match against seventh-seeded Arthur Fils of France, who beat third-seeded Stefanos Tsitsipas of Greece 7-6 (5), 6-3. Fils never faced a break point in the match.
