In one of the more bizarre scenes to unfold on the professional tennis circuit this year, ATP world No. 407 Svyatoslav Gulin was defaulted during his match against Alejo Sanchez Quilez at an ITF tournament, despite being comfortably ahead (7-5, 3-6, 4-0).
Gulin was leading 4-0 in the deciding third set when the shocking incident occurred. After winning a point — a moment that would typically boost a player's momentum — Gulin inexplicably turned his attention to the chair umpire. Instead of celebrating the point, Gulin pointed directly at the umpire and unleashed a series of obscene gestures, followed by a torrent of verbal abuse with vulgar words such as 'b{expletive} me'.
The chair umpire, adhering to the ITF’s strict code of conduct, had little choice but to immediately default Gulin from the match. The decision handed the victory to Sanchez Quilez, leaving Sanchez, fans, and tournament officials stunned by Gulin’s outburst.

He cussed at the umpire and made these obscene gestures…
Leading 4-0 in the 3rd set…
That’s one way to lose a tennis match.

It remains unclear what triggered Gulin’s frustration, especially given that he was in complete control of the match. Incidents of default are rare at the professional level, and typically reserved for the most serious breaches of behavior. Gulin’s default joins a short but infamous list of players who have been disqualified for on-court misconduct, highlighting the importance of maintaining composure no matter the circumstances.
The ITF is expected to review the incident and could hand down additional penalties, including possible fines or suspensions. Meanwhile, Gulin will be left to ponder over what could have been an easy third set and a subsequent victory as well as a few hard earned, precious points on the tour.
