Yes. Aces allowed repeat from one half of the year to the next, and reading both sides predicted the last 12 weeks of aces with an average miss of 1.71 aces, against 1.78 from the server alone, over 1,417 player matches. Rates came only from matches before those weeks.
What the returner does to the top WTA clay servers
Estimated aces over an average 10.7 service games: the server's rate, times the returner's index, times service games. The index is pulled toward 100 first, because only part of it repeats (correlation 0.71). A rough read for sizing an ace line, not a prediction.

Using ace matchups on a prop
Start with the server
Hailey Baptiste hits 0.54 aces per service game. That is a serve index of 288, where 100 is the WTA clay average of 0.19.
Check who is returning
Linda Noskova has a return index of 236, the highest here. Tamara Korpatsch has 34, the lowest. A line that ignores the returner ignores that gap.
Multiply it out
Over an average 10.7 service games, Hailey Baptiste works out to about 5.8 aces against an average returner, 11.4 against Linda Noskova and 3.1 against Tamara Korpatsch. The returner's index is pulled toward 100 first, because only part of it repeats (correlation 0.71).
Adjust for the court
Then check the court speed index for this week's event. Aces per match change a lot from clay to grass. Today's line and the hit rate against it are in PickFinder.
How this is counted
Counts finished singles matches, Nov 2, 2025 to Nov 2, 2026. Aces per match is the player's aces divided by matches. Aces allowed are the opponent's aces in those matches. Per-game rates divide by service games played and by the opponent's service games, so a long match doesn't inflate them. Serve and return indexes compare those rates with the WTA clay average, set to 100. 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 10+ matches to appear. Hard includes indoor hard. The correlations compare the first 26 weeks with the last 26 for players at this level with 80+ games in each, across all surfaces, and the prediction test sets rates only from matches before the last 12 weeks.

Are aces allowed a real skill or just luck?
A player's aces allowed in the first 26 weeks correlated 0.71 with the last 26 across 121 players, so it repeats. Aces hit correlated 0.86. Adding the returner moved the average miss on aces from 1.78 to 1.71 over the last 12 weeks.
Why use per-game rates as well as per-match?
Match length moves the count. An average WTA clay match has 10.7 service games per player, and a player who wins quickly serves fewer. Per-game rates take that out.
