Wimbledon:Two-time defending champion Novak Djokovic held every service game Monday and reached his 50th Grand Slam quarterfinal by beating No. 17-seeded Cristian Garn at Wimbledon, 6-2, 6-4, 6-2.
Djokovic earned his 12th quarterfinal berth at Wimbledon, which ties him with Arthur Gore for third place on the men's all-time list, behind Roger Federer's 18 and Jimmy Connors' 14.
Three men became first-time Wimbledon quarterfinalists, including No. 25 Karen Khachanov of Russia, who won a bizarre fifth set to beat American Sebastian Korda on his 21st birthday, 3-6, 6-4, 6-3, 5-7, 10-8. With both players battling fatigue and nerves, there were 13 services breaks in the final set.

For Korda, it was a disappointing end to an otherwise impressive Wimbledon debut.
Khachanov will next face No. 10 Denis Shapovalov, who hit 15 aces and beat No. 8 Roberto Bautista Agut 6-1, 6-3, 7-5.
Khachanov and Shapovalov joined Wimbledon's final eight for the first time, as did No. 7 Matteo Berrettini, who became the first Italian man in 23 years to reach the quarterfinals by ousting Ilya Ivashka 6-4, 6-3, 6-1.
Top-ranked Ash Barty also became a first-time Wimbledon quarterfinalist when she beat French Open champion Barbora Krejckov 7-5, 6-3. Barty was troubled again by a shaky serve but saved eight of 10 break points and did manage an ace on match point to end Krejckov's 15-match win streak.
