How to Research Tennis Player Props: Games Won, Aces and Matchups

In tennis there's no team to hide behind and no minutes to project. A player's line depends on one opponent, one surface and how long the match lasts. That's why tennis props reward research more than almost any other sport, and why a player's recent average can be the least useful number on the screen. Our example is Taylor Fritz's games won line against Carlos Alcaraz in the Paris quarterfinals on November 6, 2026.

The board

The tennis props board covers ATP, WTA and Challenger matches, with lines for games won, total games, aces, double faults, break points, sets and fantasy score. Each line sits next to the same prop at the other apps, the sportsbooks and the prediction markets, which often price tennis quite differently.

Read the game log, then question it

Fritz's line was 11.5 games won. He cleared it in 8 of his last 10 matches, averaging 12.7, and in 13 of his last 15 (87%). The sportsbook consensus at the top of the chart leaned over at 52.7%, and one app priced the over at -143.

Now ask who those matches were against. Most of a player's recent matches come from early rounds against lower-ranked players. Alcaraz was ranked 3rd in the world; Fritz was 12th. Use the Opponent filter, the Court Type filter and the head-to-head column to see how the number holds up against stronger players on the same surface.

The matchup panel

The Matchup tab puts the match in one card: round, surface, format, rankings and the win probability from the odds. Fritz was a 28% underdog (+254) on an indoor hard court, best of three sets. The "win rate with these odds" line shows how players have done at a similar price: Fritz had won 0 of 2 matches as this big an underdog, while Alcaraz had won 10 of 11 as this big a favorite.

A lopsided match is a warning for games won, because a straight-sets loss can end at 6-3, 6-4. But the next panel shows why it isn't the whole story.

Advanced averages: hold rate and head-to-head

Advanced Averages splits a player's last 15 matches by surface, by the opponent's handedness and by head-to-head. Fritz held serve 90.5% of the time overall and won 13.9 games a match. Against Alcaraz he was 0-3, yet he still averaged 14.3 games won, because those matches were long: 32.7 total games on average. He held serve 81.3% of the time against him.

That's the key to games won props. Losing the match and going under are not the same thing. A big server who holds most of his service games can lose a match 6-7, 7-6, 4-6 and still win 17 games. Before you trust a head-to-head, check the Best Of filter: men's Grand Slam matches are best of five sets and inflate the game counts.

Tennis checklist

1. Format: best of three or best of five.
2. Surface, using the Court Type filter.
3. Hold percentage and break points won, for the player and the opponent.
4. The opponent's level in each match of the recent log.
5. Win probability. Heavy favorites can win quickly, which hurts overs for both players.
6. Head-to-head, filtered to the same format.

When a line checks out, add it to the Pick Builder with the star button and send it to PrizePicks or Underdog. The tennis research page lists every market and tour we cover.
