Master Yi vs Sion Matchup Summary

The Master Yi vs Sion matchup is a decisive matchup in League of Legends ranked play. Based on 33 recent matches analyzed, Master Yi wins with a 54.5% win rate compared to Sion's 45.5%, giving Master Yi a 9.1 percentage point advantage. Game phase dynamics play a critical role here: Master Yi controls the early laning stage, but Sion outscales as the game goes longer. The matchup shifts dramatically depending on game length — Master Yi needs to press advantages before Sion reaches their power spikes, while Sion should focus on safe farming and hitting key item breakpoints. The most significant statistical gap is in crowd control, where Sion leads by 1.1s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Master Yi players can confidently pick into Sion and play aggressively from level 1. Look to establish lane dominance early through favorable trades and zone Sion away from CS whenever possible. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Master Yi dominates the early game (first 15 minutes) with a commanding 75.0% win rate — a 50.0 percentage point lead over Sion. This lopsided early game means Master Yi can dictate the pace of the lane from level 1, controlling trades, wave state, and river priority.

Sion is far superior in the late game (25+ minutes), boasting a 57.1% win rate — 14.3 points above Master Yi. Extended games heavily favor Sion, whose kit and scaling make them a dominant force in team fights and objective control.

This matchup features a dramatic power shift: Master Yi must aggressively press their early advantage and close out the game before Sion reaches their scaling breakpoints. If Sion 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.
