ANTWERP, Belgium: Germany’s Andrea Petkovic won the WTA Diamond Games tournament on Sunday when her final opponent Carla Suarez Navarro pulled out before the match with a neck injury.

Petkovic’s victory is her sixth on the WTA Tour and will ensure she breaks into the world top ten when the new rankings are released.

“I woke up in the morning and I felt this pain in my neck,” said Suarez Navarro.

“I went to the physio to get treatment and tried to play at 11:30, then had physio again and tried to play again at 2:15, and I just couldn’t serve. I couldn’t play like I wanted. So I had to pull out of this final.

“I’m really sorry. I love this tournament and I had a great week. I really tried today.”

For the 27-year-old Petkovic, it was her fourth title in ten months, as she continues her return to form after a career-high ranking of world number nine after reaching since reaching the quarter-finals at the US Open and Australian Open in 2011.

Injuries saw her slide down the rankings and outside the top 100 but a strong 2014 season, including a run to the French Open semifinals, shows she is back to her best.

Hantuchova takes third Pattaya Open title

In Pattaya, Thailand: Slovakia’s Daniela Hantuchova took the WTA Pattaya Open on Sunday with a gripping three-set 3-6, 6-3, 6-4 victory over Croatian Ajla Tomljanovic.

The win is the third for Hantuchova in Pattaya, who took back-to-back titles in 2011 and 2012.

But it was far from plain sailing against a 21-year-old Croatian rival who was ranked five places above her, enjoys a ten-year age difference and took the first set 3-6.

With an early lead in the second, Tomljanovic appeared on course for a breakthrough tour win.

But a dogged Hantuchova refused to give in, clawing her way back into the game to take the set 6-3.

Both women had endured punishing three-set semifinals on Saturday, with baseliner Hantuchova prevailing over New Zealand’s Marina Erakovic, while Tomjanovic took nearly three hours to vanquish seventh-seeded Monica Puig.

The pair were again forced to slug it out in a tight third set that saw the right-handed Croat break back after dropping serve early on.

The pair then traded games as the match crept toward the two-hour mark, before another Hantuchova break saw her seal victory 6-4.

The 73rd-ranked Hantuchova recently changed coaches, taking on former Li Na and Justine Henine mentor Carlos Rodriguez.
