Wildcard Adam Walton has pulled off the biggest victory of his career at the French Open, staying cool in the Paris heat to shock a frazzled Daniil Medvedev for the second time in nine months.
The Queenslander took advantage of one of the former world No.1's Jekyll and Hyde days, hanging tough in the final set to come from behind and win 6-2 1-6 6-1 1-6 6-4 in three hours 22 minutes on Court Suzanne Lenglen.
When he was 4-2 down in a much more closely fought fifth set after four curiously uneven stanzas, it looked as if the 27-year-old from Brisbane would miss out on repeating his previous career-best triumph over Medvedev at the Cincinnati Open last August.
But he regrouped, won the next two games and then survived a couple of break points in the crucial penultimate game, before the Russian imploded to be broken to love.
