Wozniacki back to winning ways in Luxembourg
Caroline Wozniacki of Denmark returns a shot against Angelique Kerber of Germany during their semi-final match in the Pan Pacific Open tennis tournament in Tokyo on September 27, 2013
It was Wozniacki's first title since the Kremlin Cup in Moscow last year, and came on a weekend when boyfriend Rory McIlroy finished second in the Kolon Korean Open.
And former world number one golfer McIlroy indicted that the two are still very much an item, despite recent reports of a break-up, referring to her as “my girl” in a tweet after her Luxembourg success.
McIlroy send out a tweet praising Wozniacki on the 21st title.
"#21 #luxembourg #mygirl @CaroWozniacki," the Northern Irish golfer tweeted.
Neither confirmed the rumoured split, and Wozniacki still uses a photograph of herself and McIlroy as her Twitter profile picture.
She tweeted after her win.
"Thank you for all the support this week! Great to win a title this year! #21."
Wozniacki, ranked ninth, who beat this year's Wimbledon runner-up Sabine Lisicki in the semi-finals, gave 57th-ranked Beck no opening in their first meeting.
"This result in Luxembourg is going to give me a lot of confidence," the 23-year-old.
Wozniacki, an alternate for the season-ending WTA Championships which starts in Istanbul this week, had seen a slump in form with her best result this season being runner-up in Indian Wells.
Beck said she had learnt a lot in a week that saw her reach her first WTA final, her best previous run was to the semi-finals in Katowice last April.
The 19-year-old said she had "really enjoyed this week full of lessons for the future".
