Highlights

• • Market price (1.179) implies 84.8% — we estimate ~90% true chance
• • Opponent has small sample and poorer results, increasing favoritism for Biryukov

Pros

• + Clear experience and match-volume advantage
• + Recent serve metrics indicate strong effectiveness in recorded matches
• + Current odds present a measurable edge vs our probability estimate

Cons

• - Neither player shows recorded grass experience in the provided data, increasing upset variance
• - EV is modest (~6%) — outcome variance still meaningful in a single match

Details

We assess Petr Bar Biryukov as a clear favorite based on a substantially better career match volume and win-loss profile (46-23 vs 4-10) and stronger recent serve metrics in the research. Seita Watanabe has a small sample, poor win rate and listed surfaces are clay/hard only, while the match is on outdoor grass which increases variance but still favors the more experienced player. The market decimal price for Biryukov (1.179) implies ~84.8% win probability; we estimate his true win probability at ~90% given the quality gap and qualifier context. At our estimate this price offers positive expected value: EV = 0.90 * 1.179 - 1 = 0.0611 (~6.1% ROI).

Key factors

• • Large disparity in career volume and win-loss record favoring Biryukov (46-23 vs 4-10)
• • Watanabe has limited match exposure and no listed grass experience (surfaces: clay, hard)
• • Market-implied probability (≈84.8%) is below our estimated win probability (~90%), producing value
