Cape Town - Caroline Wozniacki has defended her message of congratulations to Jordan Spieth in winning the Masters, saying it was not a dig at former fiancée, world No 1 Rory McIlroy.

The Danish tennis star copped criticism on Monday after posting a Twitter message for Spieth in admiration at how he managed to see the golf tournament through after getting off to a winning start.
"Congratulations to @JordanSpieth on winning @TheMasters! Extremely impressive how he came out firing from the start and never looked back!" she wrote.
The comment was considered a jibe at her ex by some of her Twitter followers after the golfer broke off their engagement in May last year.
But Wozniacki was not impressed, later posting on Twitter to say she had moved on.
"Tweeps I was congratulating Speith (sic) on his win, nothing else.. It's time for some of you to move on from the past. Thank you!"
Following the break-up, McIlroy's golf form improved, winning two majors en route to re-claiming the world No 1 ranking.
Wozniacki's tennis form has been up and down since the break-up, though she did make the final of the 2014 US Open.
Wozniacki has also taken up marathon running, completing the New York Marathon in November.
Earlier this year she fulfilled her dream to model for Sports Illustrated's swimsuit edition.
