Yo Dominik, love the unforced errors angle!

You’re so right about that stat being a sneaky way to catch players who crack in clutch moments. I’ve been burned betting on big servers who look unbeatable but then spray errors when the pressure’s on. On clay, like you said, those long rallies expose sloppy play, and I’m all about digging into recent match data for that.
For tennis, I’m also big on return points won—it’s a killer stat for spotting underdogs who can hang in rallies and steal games. Especially on slower surfaces like clay, where returners get more chances to shine. I cross-check it with second-serve points won because if a player’s second serve is shaky, they’re toast against a solid returner. For example, I’ve noticed some of the lower-ranked European grinders on the ATP tour quietly rack up return points, and that’s helped me snag some juicy upset bets.
Another thing I peek at is hold percentage versus break percentage. It’s not just about who’s serving bombs but who’s consistent at holding serve and converting break points. On hard courts, I lean toward hold stats, but on clay, break stats are where it’s at—players who can’t break get stuck in those marathon sets. I usually pull these numbers from the last 3-5 matches to keep it fresh.
Oh, and don’t sleep on fatigue factors!

If a player’s been grinding through three-setters in the last couple of tournaments, their error count creeps up, and their return game gets lazy. I check match durations and tournament schedules to gauge who might be gassed. Saved me from betting on a “favorite” who was running on fumes last month.
What’s your go-to site for error stats, Dominik? I’m using a mix of ATP’s official site and some betting apps, but I’m always hunting for better data. Anyone else got a stat they swear by? Let’s keep this thread alive!
