Wimbledon ATP: Roman Safiullin vs Botic van de Zandschulp

Platform comparison

Market context

Roman Safiullin faces Botic van de Zandschulp in a second-round Wimbledon ATP clash originally set for 6:00 AM ET today, yet the market currently prices Safiullin’s advancement at 0% despite his recent five-set qualifying win over Jerome Kym[1]. This near-total dismissal of Safiullin’s chances is stark, especially given his career-low ranking near 130 and a 0-2 start to the 2026 season, which suggests the crowd has overreacted to his early struggles rather than assessing the grass-court matchup fairly[1].

Historically, similar 0% crowd-implied probabilities in Grand Slam second rounds have rarely held when the underdog secured a grueling qualifying victory, as seen in 2024 when players with comparable qualifying fatigue still advanced against higher-ranked opponents on grass. In those cases, the market’s initial pessimism corrected within hours once the match began, with the underdog’s resilience proving the crowd’s assessment flawed[3].

Traders should monitor the live match start time and any injury updates for van de Zandschulp, who is playing his second-round match after a tight first-round tiebreak win[4]. The All England Club’s schedule and any weather delays could also shift the probability, as grass-court matches are sensitive to surface conditions and player freshness[2]. Recent Eurosport coverage confirms both players are scheduled for the match, with no indication of cancellation yet[5].
