The German Lisicki, who is now 1-2 in her career Wimbledon semis, lost to France's Marion Bartoli in last year's finale here.
The 13th-seeded Canadian Bouchard reached her third straight Grand Slam semifinal with a 6-3, 6-4 upset victory over ninth-seeded German left-hander Angelique Kerber at the All England Club.
The 22-year-old Romanian Halep and 20-year-old Bouchard have reached at least the quarterfinals at all three Grand Slams so far this year -- the only players to have done so. And Bouchard is the only woman to reach the semis at all three majors in 2014.
Halep is 1-0 versus Bouchard, with the win coming at Indian Wells back in March.
Thursday's other semifinal will pit sixth-seeded Petra Kvitova against 23rd- seeded fellow Czech left-hander Lucie Safarova. Kvitova titled here in 2011 and was also a semifinalist in 2010. Safarova will perform in her first-ever Grand Slam semi in her 37th major event.
The formidable 24-year-old Kvitova is a perfect 5-0 lifetime against the 27- year-old Safarova, with four of the meetings coming this year already, including a win on grass in Eastbourne just two weeks ago.Copyright © 2015, The Baltimore Sun
