Master Yi vs Sion Matchup Summary

The Master Yi vs Sion matchup is a decisive matchup in League of Legends ranked play. Based on 34 recent matches analyzed, Sion wins with a 55.9% win rate compared to Master Yi's 44.1%, giving Sion a 11.8 percentage point advantage. Game phase dynamics play a critical role here: Sion controls the early laning stage, but Master Yi outscales as the game goes longer. The matchup shifts dramatically depending on game length — Sion needs to press advantages before Master Yi reaches their power spikes, while Master Yi should focus on safe farming and hitting key item breakpoints. The most significant statistical gap is in crowd control, where Sion leads by 1.3s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Sion has a strong advantage in this matchup. Master Yi players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Sion overextending. Avoid prolonged trades and wait for team fights where positioning and coordination matter more. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Damage
948Master Yi
860Sion

Economy
13,232Master Yi
13,064Sion
Master Yi and Sion generate nearly equal gold per game, with just a 168 gold difference. Neither champion has a clear economic advantage, so gold leads will depend on individual play quality, kill participation, and objective contributions.
Utility
0.1Master Yi
1.4Sion
Sion brings significantly more crowd control than Master Yi, with 1.3 more seconds of CC per minute. This large utility gap makes Sion far more valuable in setting up jungle ganks, controlling objectives, and locking down targets in team fights. Master Yi should invest in tenacity and position carefully to avoid being chain-CC'd.
Sustain
1,187Master Yi
2,774Sion
Sion vastly out-sustains Master Yi, healing and mitigating 1,587 more damage per minute. This massive durability gap means Sion can absorb significant punishment and remain in lane while Master Yi is forced to recall.

Best Master Yi Build Against Sion

Berserker's Greaves is the optimal boots choice against Sion, providing the mobility and stats Master Yi needs most in this matchup. The top-performing core items for Master Yi against Sion are Kraken Slayer, Blade of The Ruined King and Guinsoo's Rageblade.

Sion dominates the early game (first 15 minutes) with a commanding 78.6% win rate — a 57.1 percentage point lead over Master Yi. This lopsided early game means Sion can dictate the pace of the lane from level 1, controlling trades, wave state, and river priority.

Master Yi is far superior in the late game (25+ minutes), boasting a 60.0% win rate — 20.0 points above Sion. Extended games heavily favor Master Yi, whose kit and scaling make them a dominant force in team fights and objective control.

This matchup features a dramatic power shift: Sion must aggressively press their early advantage and close out the game before Master Yi reaches their scaling breakpoints. If Master Yi survives the laning phase without falling too far behind, the matchup flips in their favor. Dragon and Rift Herald control are pivotal — the team that secures early objectives can snowball or buy time to scale.
