KAPALUA, Hawaii — Rory McIlroy is claiming his first win of the new year — his engagement to tennis star Caroline Wozniacki.

One of the top power couples in sports announced their engagement on Twitter. A spokesman for McIlroy confirmed that he popped the question in Sydney, where Wozniacki is starting to prepare for the Australian Open in Melbourne.

McIlroy tweeted, “Happy New Year everyone! I have a feeling it’s going to be a great year!! My first victory of 2014.” He added a hash tag, “She said yes!!” Wozniacki also tweeted the news. Their tweets included a photo collage of her engagement ring, a photo of them together and fireworks over the Sydney Harbor.

Also on Tuesday, Oakley’s dispute against McIlroy and Nike officially ended.

Golfweek reported that Judge James Selna of the U.S. District Court for the Central District of California ruled in favor of Nike in the matter, which stemmed from the agreement McIlroy signed with the company after leaving Oakley late in 2012.

Oakley filed a five-count complaint against Nike and McIlroy, claiming it had the first right of refusal in re-signing McIlroy.

McIlroy and Oakley settled their dispute, although terms were not announced. Selna’s ruling was made on Dec. 18.

“We are very pleased the proceedings against Rory have been resolved,” Pat McIlvain, Oakley’s vice president of global sports marketing, said in a statement. “We enjoyed an excellent relationship with Rory as an Oakley brand ambassador.

“He conducted all his engagements on our behalf with energy and professionalism. We recognize that, in his business dealings with us that were the subject matter of this dispute, Rory was represented by his agent.”

In addition to removing the breach-of-contract count from the list of allegations, the court’s decision dealt with the other claims in the complaint, including interference with contractual relations, violation of a California code on unfair competition, breach of implied covenant of good faith and fair dealings, and declaratory relief.

“We are pleased with the court’s decision as it reflects the professional approach with which we undertook the negotiations,” Nike said in a statement.
