Garbine Muguruza has taken down the world No. 1 to reach her first Western & Southern Open final.

The 23-year-old Spanish-Venezuelan tennis player and reigning Wimbledon champion beat World No. 1 Karolina Pliskova to secure a place in Sunday’s final of the Western & Southern Open in Cincinnati, where she’ll take on No. 2 seed Simona Halep.

Muguruza came through 6-3, 6-2, having set the tone after breaking Pliskova in the very first game.

Muguruza kept the pressure on Pliskova’s serve, securing a key break to lead 4-2 in the second set before closing out victory in one hour and 21 minutes after taking a fifth match-point chance against the top seed.

Halep, meanwhile, could take over from Pliskova at the top of the WTA rankings if she’s able to win the tournament.

Halep had to battle past British No. 1 Johanna Konta 6-4, 7-6 (7/1) in their quarterfinal, which lasted almost two hours.

However, Halep coasted through the second semifinal with a 6-2, 6-1 win over Sloane Stephens in just 56 minutes.
