What is LeagueLab?

LeagueLab is a League of Legends esports match history site. We cover nine regional leagues — LCK, LPL, LEC, LCS and others — plus three international events such as MSI and EWC: results, ban/pick, pro player records, champion stats and team head-to-head records. You can open a single game down to its scoreboard, objectives, gold curve and item builds, or group games by patch and tournament to see how the meta moved.

Results, drafts and standings come from Leaguepedia, the open esports wiki; detailed in-game numbers such as gold, experience, vision and timelines come from Riot's official Match V5 API. While a tournament is running a lightweight collector picks up new games every 30 minutes, and a full daily sync reconciles standings, rosters and patch metadata. On top of that sits a layer we compute ourselves: laning stats are cut at whichever comes first, the first tower or the 15-minute mark, and measured as gold and CS differences against the opposing laner, while champion tiers shrink noisy small-sample win rates toward a laning-based prior and add pick/ban presence asymmetrically. The formulas and their limits are written up in the metrics guide, unfamiliar abbreviations in the glossary, and our coverage and operations in about this site.

There are four main places to explore. Pick a team in Teams and you get standings, recent games, the roster and an auto-generated analysis paragraph on one page. League metrics sorts the top players by position in a single table, and each name links through to that player's own page. Champion stats covers pick, ban and win rates by patch and tournament along with champion matchups, while Champion analysis shows the skill order, starting items, core builds and runes pulled from pro players' solo queue games. Today's matches and the games that just ended sit in the schedule strip and recent-games feed at the top of this page.
