Prediction markets put the probability at 28%: Winston-Salem Open: Jan Choinski vs Mees Rottgering. Currently, markets see this as unlikely (28% YES). Jan Choinski approaches this first round with a 3-7 main draw record this season and two consecutive losses.
The Winston-Salem Open: Jan Choinski vs Mees Rottgering first-round match was scheduled to begin Monday, August 24, 2026 at approximately 3:10 PM ET on the outdoor hard courts of Wake Forest University in Winston-Salem, USA. The ATP 250 event, the final tune-up before the US Open, pits Germany's Jan Choinski against Dutch qualifier Mees Rottgering in the Round of 64. The two players had never previously met, leaving no head-to-head reference point to separate their profiles. Broadcast coverage was slated for Sky Sports Tennis in the UK and the Tennis Channel in the USA. [The Stats Zone, Aug 24]
The ranking gap framed the contest: Choinski sat at roughly 75th–77th in the live rankings, while Rottgering languished near 389th–418th, giving the match a ranking-progression stake for both. Form, however, complicated the pricing. Choinski entered with a modest 3-7 main-draw record this season and two consecutive losses, whereas Rottgering arrived on a high, having won two qualifying matches at Winston-Salem by decisive scorelines of 6-4 6-1 and 6-1 6-0. Serve statistics favored Choinski, who posted a 64.9% first-serve rate and 79.5% service games won, against Rottgering's 57.5% and 68%. [TennisTemple, Aug 24]
Bookmaker odds installed Choinski as the favorite at around $1.61, with Rottgering the underdog near $2.30, reflecting the higher-ranked player's superior tour pedigree despite recent slumps. The stylistic clash centers on Choinski's need to serve aggressively and efficiently against an efficient returner in Rottgering, who won 57.4% of second-serve return points and converted 48% of break points. A win for Choinski would build last-minute momentum ahead of the US Open, while a Rottgering upset would extend a breakout Winston-Salem run. The Winston-Salem Open: Jan Choinski vs Mees Rottgering outcome advances the victor into the second round. [Dimers, Aug 24]
