London - Romania's Simona Halep fought back to reach her second Wimbledon quarter-final with a 6-7 (5/7), 6-4, 6-3 victory against American ninth seed Madison Keys on Monday.
Fifth seed Halep, a former French Open runner-up, made the semi-finals at the All England Club in 2014 and will face German fourth seed Angelique Kerber in the last eight as she bids to emulate that run.
