Pablo Cuevas has pulled off a big upset…

The 29-year-old Uruguayan tennis player upset third-seeded Bernard Tomic 3-6, 6-3, 6-4 on Wednesday to reach the quarterfinals of the Valencia Open.

Cuevas landed just 38 percent of his first serves in the first set but saved six of the seven break points he faced in the second and then earned the only break in the decider to clinch the win in 1 hour, 48 minutes.

Vasek Pospisil also reached the quarterfinals by beating Britain’s Aljaz Bedene 6-3, 6-4, while American Steve Johnson set up a second-round meeting with second-seeded Feliciano Lopez by ousting Martin Klizan 6-3, 6-4.
