PickFinder Team•Updated:
Maja Chwalinska has beaten the closing tennis odds by the most on the WTA tour over the last 52 weeks: 70.3% wins against 51.8% implied, over 37 matches. Sofia Kenin has lagged them the most, 22.9% against 42.2%. Most of this looks like noise: 5 of 104 players sit outside the noise band where chance alone would put about 4.7, and a player's gap in the first 26 weeks correlates 0.13 with the last 26.

WTA win rate against closing odds, biggest gap first
How good is the closing price?
Each band is the favorite's no-vig chance at the close. Power de-vig tracks the real win rate. Proportional de-vig, the common shortcut, understates favorites, which would make every heavy favorite look like a market beater. This page uses power.
Using market beaters on a prop
Read the gap
Maja Chwalinska won 70.3% against 51.8% implied, a gap of +18.4 points over 37 matches. The noise band for that sample is ±14.8, so a gap has to be that big before it stands out at all.
Split favorites and underdogs
Maja Chwalinska is 13-4 as a favorite and 13-7 as an underdog. Sofia Kenin is 3-6 and 5-21. It shows where a record came from.
Treat it as context for the price
This explains what has happened, not what comes next. A player's gap correlates 0.13 from one half of the window to the next, across 94 players. Don't read a big gap as a reason to bet.
Start from the close
Favorites priced at 80% to 90% won 86.5% of 505 matches against 84.6% implied by the power de-vig. The closing price is hard to beat, so treat it as your starting point. Today's line and the hit rate against it are in PickFinder.
How this is counted
Counts finished singles matches with a closing moneyline on both players, Nov 2, 2025 to Nov 2, 2026. 96% of prices are Pinnacle's, and the rest come from another major book. Implied % removes the vig with a power de-vig, because it matches real win rates. The proportional shortcut understates favorites: at 80% to 90% it gives 82.9%, power gives 84.6%, and they actually won 86.5%. Gap is win % minus average implied %. The noise band is two standard deviations of what those prices would produce by chance over that many matches. Beyond noise means the gap is outside it, and with this many players some will be by luck, which is why the page shows the count. Retired matches and walkovers are left out. Tour level means WTA events, the Grand Slams and the Finals, qualifying included. Challenger and WTA 125 matches are left out and have their own view, because they would flatter anyone who plays down a level. Team cups are left out too. A player needs 30+ priced matches.
