Japan's Yoshihito Nishioka shrugged off a 36-ace barrage, as well as a 38-centimetre height difference, to defeat John Isner on Wednesday to reach the Wimbledon second round for the first time.
Nishioka won 7-6 (7/5), 2-6, 6-3, 6-7 (3/7), 6-4 against the 2018 semi-finalist who also unleashed 87 winners.
Standing at just 5ft 7ins (1.70m) to the 28th-seeded American's 6ft 10in (2.08m), the 58th-ranked Nishioka triumphed after three previous first round exits.
The 25-year-old will face Aljaz Bedene of Slovenia for a spot in the last 32.
