The former US Open champion was outplayed by Walton 6-2, 1-6, 6-1, 1-6, 6-4 in three hours and 22 minutes on the clay and claimed the biggest win of his career, as well as his first over a top-10 player.<\/p>\r\n\r\n
It was Medvedev\u2019s seventh first-round exit at the French Open in 10 visits and leaves him with a dismal 0-4 record in five-set encounters at Roland Garros.<\/p>\r\n\r\n
The match swung from side to side in a real battle between the two, and it took a lot for Walton to keep going as Medvedev looked to gain the upper hand in the last three sets, even needing a timeout at the change of ends in the second set to take a salt tablet while battling the Paris heat.<\/p>\r\n\r\n
Medvedev was seemingly cruising towards victory when he took a 4-2 lead in the fifth, but Walton turned it around by winning four consecutive games to seal victory as Medvedev unraveled in the last set. <\/p>\r\n\r\n
Medvedev was caught on camera getting an on-court reprimand from his wife over his actions at times throughout the encounter.<\/p>\r\n\r\n
World No. 97 Walton, playing his first clay-court match of the year, admitted that last year's victory over the Russian at the Cincinnati Masters had given him a taste of what he could do against the 27-year-old.<\/p>\r\n\r\n
\"Pretty tired now. It was an up-and-down match. I felt like the ebbs and flows of the match were quite large today,\" Walton said.<\/p>\r\n\r\n
\"Just really proud of my efforts in the fifth set to come from a break down to get the win. It's huge. Beating him in Cincinnati definitely gave me the belief today. I knew I could do it. I believed. Just really happy with the performance. Just really excited right now.\"<\/p>\r\n\r\n
Walton will play world No. 108 Zachary Svajda of the US in the second round.<\/p>\r\n\r\n
Elsewhere, there was success for French tennis, with 17-year-old Moise Kouame producing an incredible upset over former US Open champion Marin Cilic on his Grand Slam debut to win 7-6(4), 6-2, 6-1.<\/p>\r\n\r\n
Walton will play world No. 108 Zachary Svajda of the US in the second round.<\/p>\r\n\r\n
Kouame\u2019s victory saw him become the youngest Frenchman to win at Roland Garros since 1991, and he will next face Adolfo Daniel Vallejo after Britain's Cameron Norrie pulled out of his first-round encounter.<\/p>\r\n\r\n
