Sinner Tradeoff Between Serve And Baseline
- Yannick Sinner's baseline numbers dipped during the Sunshine Double while his serving rose sharply.
- Gill gives baseline points won at 53% vs 57% 52-week average and notes Sinner still remains elite because serve has compensated.
Evaluate Second Serves By Speed And Unreturned Rate
- Measure second-serve quality by both speed and unreturned percentage, not just double-fault avoidance.
- Gill lists leaders: second-serve speed leaders (Opelka 116 mph, Vasko 113, Petchy Pericard 112) and unreturned% (Opelka 40%, others far lower).
Clay Extends Rallies And Reduces Aces
- Clay rallies are measurably longer and aces rarer than hardcourts or grass, changing point construction.
- Using slam data Gill cites average rally length: Australian 4.01, Roland Garros 4.55 and ace rates Australian 10.8% vs Roland Garros 7.4%.
