Questions

How do I ask for WTA data?

Every tool takes league: "wta". Seasons are calendar years; tournament ids look like "188-2025".

Does it have aces and break points?

No. ESPN publishes scores, not serve statistics, for tennis. Match statistics here are counted from the score: sets, games, tiebreaks, deciding sets and 6-0 sets.

Tennis data from public ESPN data. Surfaces and ratings are ours.
