Pulled the ATP Finals data and found something mental about Rublev's endurance patterns. His winner rate sits at 42% through four sets in matches under 3 hours, but drops to just 19% in fifth sets when the match has already gone over 3 hours. Sample size is 23 matches since Wimbledon 2023.

Tsitsipas is sitting at +280 for their potential ATP Finals clash, and his fifth set conversion rate is 67% this season when matches exceed the 3-hour mark. Rublev's forehand starts spraying wide after the 2h45m threshold — tracked his unforced error rate climbing from 11% to 28% in those decisive sets.

The Turin indoor conditions favour longer rallies, and if this one goes the distance, those stats suggest Tsitsipas has serious value at nearly 3-to-1. Anyone else factoring in these fatigue patterns for the Finals betting?

Absolute rubbish analysis. Rublev's been playing his best tennis in long matches this year — beat Djokovic in a 3h12m epic at Monte Carlo and demolished Sinner after 3h28m in Madrid. Your sample size conveniently ignores his clutch performances when it actually mattered.

Tsitsipas at +280 is tourist money. He's lost his last four matches that went past 2h30m, including that embarrassing collapse against Korda where he led two sets. Save your cash.

This reminds me of the 2019 ATP Finals when Thiem was getting similar long-match value against the field. I'd been tracking his fifth set conversion rates all season — 71% when matches exceeded 3 hours compared to 34% for the rest of the top-8. The bookies were slow to adjust because they focused on head-to-head records rather than endurance metrics.

Thiem's semifinal against Djokovic went exactly as the data predicted. Novak dominated the first two sets, but once we hit the 2h45m mark, Thiem's superior conditioning showed. He won 14 of the final 18 games, converting break points at an 83% rate in the deciding set while Djokovic's serve percentage dropped to 52%.

The Turin surface plays slower than most indoor venues, which historically favours the grinders over the power players. Rublev's game relies heavily on first-strike tennis — when forced into extended rallies beyond the 3-hour threshold, his weapon becomes a liability. I've got Freshbet showing Tsitsipas at +285 for their potential meeting, and that looks like genuine value given these endurance differentials.

The numbers check out but you're missing context. Rublev's 19% winner rate in long fifth sets correlates with a 34% increase in double faults after the 3-hour mark. His second serve percentage drops from 71% to 58% when fatigue sets in.

However, Tsitsipas has his own issues — 41% of his losses this season came in matches where he led 2-1 in sets. His mental fragility in decisive moments is well documented. The +280 odds reflect this inconsistency more than any endurance advantage.

Turin's 23°C court temperature and 45% humidity levels actually favour power players over baseline grinders. The ball travels 8% faster in those conditions compared to outdoor autumn tournaments. Rublev's forehand velocity advantage becomes more pronounced, not less.

Sorry for the basic question, but how do you even track these winner rate percentages during matches? Are there specific stats sites that break down performance by time periods, or is this something you calculate manually from match data?

Also, when you say Rublev's rate drops to 19% in fifth sets — is that winners per game, per point, or total winners divided by total shots? I'm trying to understand how to use this kind of analysis for my own betting.

Brilliant analysis that I'll completely ignore while backing Rublev anyway because I'm an idiot. Last week I had similar data showing Hurkacz's serve percentage drops 23% in fourth set tiebreaks, so naturally I backed his opponent. Hurkacz proceeded to serve 87% in the tiebreak and won 7-2.

I've been using Slottio for these ATP Finals bets, mainly because their interface matches my betting competence — absolutely terrible but somehow still functional. Lost £340 on Medvedev's "guaranteed" straight sets win over Alcaraz because I thought indoor courts meant no wind to affect his rhythm. Turns out air conditioning counts as environmental factors.

Your Tsitsipas logic is spot on, which means I'll definitely back Rublev and document another spectacular failure for the forum's entertainment.

Watched their Rome match live this year and the fatigue factor was obvious by the third set. Rublev's court positioning shifted 2-3 feet behind the baseline after the 2h15m mark, turning his aggressive forehand into defensive pushing. His first serve speed dropped from 124mph average to 117mph in the final set.

The live odds swung from Rublev -140 to Tsitsipas -110 during that 8-minute changeover at 4-3 in the fourth. Anyone betting in-play could see the momentum shift happening in real time. Tsitsipas started targeting Rublev's backhand with shorter angles, forcing him to generate pace from defensive positions.

The 117mph drop Alice mentioned tracks with my serve speed database — I've logged Rublev's velocity at 30-minute intervals across 47 matches this season. His average drops 6.8mph between hours 2-3, then another 4.2mph after the 3-hour mark. But here's what the fatigue narrative misses: Tsitsipas has won exactly 2 of his last 11 fifth sets, posting a 23% conversion rate when matches exceed 2h45m.

The real edge isn't backing against Rublev's declining winners — it's fading Tsitsipas when he's forced into extended rallies. His unforced error rate jumps from 31% to 47% in fifth sets lasting over 35 minutes. At +280, you're betting on a player whose mental game historically crumbles under marathon pressure.
