Wozniacki, Keys advance in Charleston

Caroline Wozniacki will face eighth seed Madison Keys in the Charleston Open final.

Caroline Wozniacko won in straight sets against Petra Martic in the semis.

Caroline Wozniacki reached her first final of the season on Saturday after defeating Petra Martic in straight sets in the semifinals of the Charleston Open.

The Danish fifth seed used a solid serve to overpower her Croatian opponent en route to a 6-3, 6-4 win in the WTA claycourt tournament.

It marked the third time Wozniacki has made the final of the Charleston event, which she won eight years ago in 2011.

“I think I served well in most of the match and I think I returned really well most of the match as well, and I just tried to stay aggressive as much as I could and tried to make her run and make her move,” Wozniacki said. “I think I did well today.”

The world number 13 had never lost to Martic in five previous meetings and an upset never looked on the cards on Saturday as she completed a win in 1hr 25min.

Wozniacki will face eighth seed Madison Keys of the United States in Sunday's final. Keys was a similarly convincing winner in her semi with Puerto Rico's Monica Puig, winning 6-4, 6-0.
