World number 92 Roman Safiullin reached his first Grand Slam quarter-final at Wimbledon on Sunday when he defeated Denis Shapovalov in four sets.
The 25-year-old Russian, who had never previously passed the second round of a major and was making his Wimbledon debut, came through 3-6, 6-3, 6-1, 6-3 against the 26th-seeded Canadian, a semi-finalist two years ago.
Safiullin had only won one match on grass prior to coming to the tournament.
