Serena Williams will meet Garbine Muguruza in the Wimbledon women's singles final after a dominant victory over Maria Sharapova.
The no. 1 and no. 4 in the world met on Centre Court but Williams extended her winning run against Sharapova to 17 with an easy 6-2 6-4 victory to remain on target for a clean sweep of the 2015 Grand Slam titles.
21-year-old Muguruza stands in her way, however, having shocked the veteran American in this competition last year when she eliminated her in the second round.
Russia's Sharapova has not beaten Williams since 2004 and surrendered the first set in just over half an hour, unaided by a double fault in her opening service game.
Sharapova fought back in the second set but another double fault gave Williams break point in game five. Untroubled again as her opponent struggled to live with the power of her delivery, Williams eased to match point with an ace before finishing the contest with another thunderous serve.
Williams meets Muguruza of Spain in Saturday's final and is wary of the damage the youngster has inflicted upon her in the past.
"It's great for her," told BBC Two. "She's beaten me before and she made me improve. It will be a great final.
"The feeling gets better every time I'm here. It's been a long time since my last final. It's really cool."
