MADRID (Reuters) - Simona Halep reached her fourth Madrid Open final with a 6-2 6-7(2) 6-0 win over Belinda Bencic on Friday and will face last year's runner up Kiki Bertens, who beat Sloane Stephens 6-2 7-5.
World number three Halep can move back to the top of the WTA rankings with a win in Saturday's final.
Twice Madrid winner Halep broke the unseeded Bencic in the first game of the first set, the Swiss's errant backhand flying out, but she broke back to tie at 2-2.
The Romanian broke for a 3-2 lead and a down-the-line shot sealed another break in the penultimate game before she served out to win it comfortably in 27 minutes.
Halep won virtually all of the long rallies, but Bencic reacted well at the start of the second set, playing more aggressively.
Bencic broke to go 3-1 up, enjoying a stroke of luck with a shot that clipped the net and dropped just over.
Halep battled back, earning a tiebreak, but Bencic won it comfortably to force a deciding set, although she immediately started to struggle.
At three games down, she cried during the changeover, with Halep immediately breaking for 4-0 when play resumed, going on to wrap up the set and the match with ease.
"It's a nice feeling to be back in the final of this special tournament, I'm really happy playing here," said Halep.
"In the second set in that tiebreak I was rushing too much, I lost control of it, but then I just calmed down, told myself I had to start the match again.
"I started to play smarter, opened the court more and became more aggressive."
Bertens had to save three set points against Stephens but eventually recorded her first victory against the American in their third encounter.
The Dutch world number seven triumphed in St Petersburg this season and is going for her ninth career title on Saturday.
"I feel unbelievable of course, it's great to be in the final and I'm happy to finish it in two (sets)," said Bertens.
"It's going to be really tough (against Halep), we played each other in the past so I know it will be a tough battle, but I'm ready for it, one more push here."
