ACAPULCO: Third-seeded Austrian Dominic Thiem powered into the quarter-finals of the Mexican Open in Acapulco on Wednesday with a 6-2, 6-3 triumph over rising Canadian star Denis Shapovalov.

Thiem, the 2016 champion in Acapulco, didn’t face a break point in his 75 minutes on court against the 18-year-old Canadian as he set up a last-eight clash with former US Open champion Juan Martin del Potro.

“I’m very happy because everybody knows how good he can play and how dangerous he is,” Thiem said of Shapovalov. “I was really on from the first point. Today was almost perfect.” Argentina’s del Potro, the sixth seed, needed three sets to get past Spain’s David Ferrer 6-4, 4-6, 6-3.—AFP
