It’s an out-of-this-world win for Carla Suarez Navarro…

The 26-year-old Spanish tennis player has stalled Venus Williams‘ recent resurgence in the quarterfinals of the Miami Open, beating the former WTA World No. 1.

Suarez Navarro, the tournament’s No. 12 seed defeated Williams 0-6, 6-1, 7-5 on Tuesday.

Williams, 34, was broken six times in the final two sets and double-faulted twice in the final game.

“Too many errors, and I was going for it the whole match,” Williams said. “Toward the end, I just never found the happy medium between being aggressive and putting the ball in the court.”

Earlier Tuesday, Andrea Petkovic became the first semifinalist at the Miami Open when she beat Karolina Pliskova 6-4, 6-2.

Petkovic, seeded ninth, arrived at Key Biscayne with a modest 7-6 record this year but has yet to lose a set. She will next face Suarez Navarro on Thursday.
