Key takeaways
- Only 4 Caitlyn vs Cassiopeia games were recorded in the Bot role on patch 26.20 — too few to say who is favored. Treat the numbers below as provisional.
How we calculate this
Games: ranked Solo/Duo and Flex games on the North America server from the patch shown. Remakes (games under 5 minutes) are excluded.
A game only counts when Caitlyn and Cassiopeia played the same position on opposite teams, so roaming, lane swaps within a team or a champion merely being in the same game never count as this matchup.
The 95% range is a Wilson score interval. Confidence comes from how wide that range is: within ±3 points is very high, ±5 high, ±8 moderate, anything wider low. Below 20 games a matchup is not classified at all.
Expected win rate combines both champions’ win rates in this lane (same games and filters) with the log5 formula: E = A(1−B) / (A(1−B) + B(1−A)). Matchup effect = observed − expected.
"What changes" compares Caitlyn's choices in this matchup with the same champion's other games in the same lane, and lists a change only when it is at least 3 points and statistically significant (two-proportion z-test, |z| ≥ 2, 20+ games).
Results are not split by rank: the sample per rank is too small for honest per-rank matchup numbers.

Usual Caitlyn build (Bot)
68.8% win rate · 93 games
Against Cassiopeia
Not enough matchup-specific build data: only 0 of 4 Caitlyn games against Cassiopeia carried a complete build, which is too few to recommend an item path from. Use Caitlyn's standard build instead.
Builds are ranked by the lower edge of their win rate range, not the raw win rate, so a build seen in a handful of wins never outranks a proven one.
