The WinBA Index: the WNBA’s top players for September 2026

Olivia Miles leads at 87 from A'ja Wilson at 86, with 193 qualified players ranked on PropBetEdge’s winning-impact rating for September 2026.

By the PropBetEdge WNBA Newsroom Published Updated Source data as of Sep 20, 11:17 PM ET

Olivia Miles leads September 2026 so far at the top of WinBA Score, PropBetEdge’s winning-impact rating, with a mark of 87 for the Minnesota Lynx on 19.5 points, 4.8 rebounds, 6 assists a game.

A'ja Wilson is a stride behind at 86, close enough that Olivia Miles’ hold on the top spot is not settled.

These are the standings as of September 20, with September 2026 still being played. The board is frozen at this point and the ranks recorded here are the ones the next edition will measure against.

WinBA Score is built only from completed WNBA games: Box Impact (points plus 1.2 times rebounds plus 1.5 times assists) measured per 36 minutes against the league, the player’s win rate, the share of her production that came in wins, and her court share. It is an association-with-winning index, not a causal estimate of wins added. 193 players qualified for the league ranking, which takes at least 10 appearances or 250 minutes.

This is the first WinBA Index, so there is no prior frozen board to measure movement against. Month-over-month risers and fallers begin with the next edition, compared against the September 2026 ranks recorded here.

Who leads each position

Guard: Olivia Miles, Minnesota Lynx — 87, No. 1 overall on 19.5 points, 4.8 rebounds, 6 assists.

Forward: Angel Reese, Atlanta Dream — 83, No. 3 overall on 16.2 points, 12.1 rebounds, 2.8 assists.

Center: A'ja Wilson, Las Vegas Aces — 86, No. 2 overall on 25.8 points, 9.2 rebounds, 3.2 assists.

The first-season watch

The highest-rated player on the board is in her first WNBA season: Olivia Miles leads the league outright at 87.

What the rankings say

The top 10 won 68% of the games they played. Because a quarter of WinBA Score is win rate and a fifth is the share of production that came in wins, the board rewards players whose output arrives in victories — which is why it is read as a winning-impact rating rather than a volume leaderboard.

Every player in the top 10 sits at or above the 88th percentile of Box Impact per 36, so none of these ratings rests on playing time alone.
