Matchup analysis
The 🎯 Baseliner archetype wins about 55% vs 🎾 All-Court across 650 matches in our dataset. That is a small stylistic lean for Thiago Monteiro here.
Baseliner players often use precise groundstrokes and court control to pressure the all-court's tactical versatility. On Clay, that can swing with conditions.
