Simona Halep reaches semifinals
The third-seeded Halep, down 4-1 in the first set, won 11 games in a row to beat 2013 finalist Sabine Lisicki of Germany 6-4, 6-0 in 57 minutes on Centre Court.
The 13th-seeded Bouchard defeated No. 9 Angelique Kerber of Germany 6-3, 6-4 to reach the semifinals at a third consecutive Grand Slam.
"I'm just excited to be in the semis again and I want to go one step further for sure," Bouchard said.
Halep, runner-up at the French Open, is the first Romanian woman to get this far at the All England Club since the Open era began in 1968. Bouchard, who hasn't dropped a set in five matches, is the first Canadian woman to reach the Wimbledon semifinals.
"I think it's a normal evolution of things as the great champions get a bit older the new ones start coming in I think it's a really exciting time for women's tennis," said the 20-year-old Bouchard, who will break into the top 10 in the rankings next week.
Halep and Bouchard are both 15-2 in Grand Slam matches this year.
Halep and Bouchard have played each other only once, with the Romanian winning.
Bouchard was in control against Kerber -- who beat Sharapova on Tuesday -- after saving four break points while serving at 3-all in the first set, a game that lasted nearly 10 minutes.
"I was really trying to stay in the moment," Bouchard said. "I knew I couldn't think ahead and things like that and that's what I've been working on for a while now to try to stay mentally in the moment. I few bad errors but at the same time I hit a few good aggressive shots and that's my game."
Halep, meanwhile, took command of her match by attacking Lisicki's weak second serve. The German won only eight of 26 points on her second serve. She also had 20 unforced errors, compared to 11 by Halep.
"She had 4-1 and then I came very well back," Halep said. "I played my best today and I was enjoying every moment because it was incredible on Centre Court."
