MADRID, Spain – Former Australian Open finalist Dominika Cibulkova finally got the big win she was looking for in 2016, surviving a second set hiccup to unseat top seeded Agnieszka Radwanska, 6-4, 6-7(3), 6-3, to reach the second round of the Mutua Madrid Open.

Cibulkova has had the game’s best on the ropes in the early rounds throughout the season – holding match points against Radwanska at the BNP Paribas Open and leading Garbiñe Muguruza at the Miami Open – but the 2009 French Open semifinalist refused to relinquish this chance against the Pole in the final match of the day on Court Manolo Santana.

Battling the crafty World No.2 for two hours and 37 minutes, each woman hit 43 winners in a high-quality affair that saw stunning power from the Slovak to edge ahead by a set and a break and serve for a spot in the second round.

On her least favorite surface, Radwanska wouldn’t back down so easily and broke back to level the set, and though she would prove unable to serve out the set herself, she snuck away with the ensuing tie-break and took a 2-0 lead in the decider.

Poised for a third straight loss to a Top 4 player at a Premier Mandatory, Cibulkova dug deep to win six of the last seven games of the match, converting all four break point opportunities in the final set and clinching victory with a thudding forehand winner.

The former World No.10 is coming off a win at the Katowice Open – having already reached a final earlier in the year in Acapulco – and a deep run in Madrid could be crucial as she aims to get back into the seeded position at major tournaments. Standing between her and the third round is Frenchwoman Caroline Garcia, who advanced earlier in the day when Johanna Konta was forced to retire with an upper respiratory illness.

Over on Court 6, Timea Bacsinszky completed an impressive turnaround from winning the GP SAR La Princesse Lalla Meryem in Rabat 24 hours earlier to edge past 2014 French Open semifinalist Andrea Petkovic, 6-4, 2-6, 6-3.

“I was aware that I would have a low in my match,” Bacsinszky said of the understandable fatigue that caused her to fall behind 5-0 in the second set.

“I needed to adapt, know I’d have my chances, and just get into it. At the beginning, it was really going well for me. But after the the end of the first set, you could see I didn’t have the tension to be committed on important points. I was angry at myself, but thinking longterm, that it would be a long match. I tried to kick my butt in the beginning of the third, and the level went up.

“I didn’t want to be brilliant, just efficient.”

Also through late on Sunday was Romania’s Irina-Camelia Begu; suffering from foot blisters in the second and third sets, Begu fought off a late charge from the Canadian youngster to survive the topsy turvy encounter, 6-4, 3-6, 6-4.
