Matchup analysis
The 🏹 Frontrunner archetype wins about 53% vs 🎾 All-Court across 123 matches in our dataset. That is a small stylistic lean for Fajing Sun here.
Frontrunner players often use fast starts and aggressive openers to pressure the all-court's tactical versatility. On Hard, that can swing with conditions.
