Master Yi vs Kai'Sa Matchup Summary

The Master Yi vs Kai'Sa matchup is a decisive matchup in League of Legends ranked play. Based on 7 recent matches analyzed, Master Yi wins with a 57.1% win rate compared to Kai'Sa's 42.9%, giving Master Yi a 14.3 percentage point advantage. Master Yi dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Kai'Sa players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential. The most significant statistical gap is in sustain, where Master Yi leads by 356 HP/min — a difference that heavily influences the outcome of trades and skirmishes. Master Yi players can confidently pick into Kai'Sa and play aggressively from level 1. Look to establish lane dominance early through favorable trades and zone Kai'Sa away from CS whenever possible. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.
