Sion vs Udyr Matchup Summary

The Sion vs Udyr matchup is a moderate matchup in League of Legends ranked play. Based on 17 recent matches analyzed, Udyr wins with a 52.9% win rate compared to Sion's 47.1%, giving Udyr a 5.9 percentage point advantage. Game phase dynamics play a critical role here: Sion controls the early laning stage, but Udyr outscales as the game goes longer. The matchup shifts dramatically depending on game length — Sion needs to press advantages before Udyr reaches their power spikes, while Udyr should focus on safe farming and hitting key item breakpoints. The most significant statistical gap is in damage output, where Udyr leads by 213 DMG/min — a difference that heavily influences the outcome of trades and skirmishes. While Udyr is slightly favored, Sion can absolutely win this lane through smart trading patterns and wave management. Focus on playing around your cooldowns, conceding CS only when necessary, and capitalizing on Udyr's mistakes. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Sion dominates the early game (first 15 minutes) with a commanding 70.0% win rate — a 40.0 percentage point lead over Udyr. This lopsided early game means Sion can dictate the pace of the lane from level 1, controlling trades, wave state, and river priority.

Udyr is far superior in the late game (25+ minutes), boasting a 85.7% win rate — 71.4 points above Sion. Extended games heavily favor Udyr, 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 Udyr reaches their scaling breakpoints. If Udyr 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.
