Eighth-seeded Elina Svitolina advanced to the third round at Wimbledon after Margarita Gasparyan had to retire with a leg injury in the second set.
Gasparyan was leading 7-5, 5-6 when she was forced to quit.
Gasparyan had been on the verge of an upset, two points from the match at 5-4 in the second, but Svitolina held and her opponent was then injured after delivering a serve at 0-15 in the next game.
