Matchup analysis
The 🪃 Counterpuncher archetype wins about 53% vs 🎯 Baseliner across 370 matches in our dataset. That is a small stylistic lean for Saisai Zheng here.
Counterpuncher players often use elite bp conversion and strong return game to pressure the baseliner's precise groundstrokes. On Hard, that can swing with conditions.
