What's new?
HOPS (Header Outcome Prediction System)
We've introduced HOPS, our aerial duel model, across three data products. HOPS estimates a player's likelihood of winning an aerial contest and is now available in:
- API Events v9.0.0 / CSV Events v9.0.0 - duel_win_probability added to shot, clearance, miscontrol, duel, and pass events where an aerial contest occurs. For aerial duels specifically, four new fields are available: hops_rating, hops_raw_rating, hops_opponent_rating, and
hops_opponent_raw_rating.
- API Lineups v5.0.0 - Player-level HOPS skill ratings (rating and raw_rating) added to a new skills object on each lineup entry.
- API Team Match Stats v2.0.0 - team_match_aerial_duel_difficulty provides the average estimated win percentage of aerial duels contested, based on HOPS player scores.
Set Piece Model 2.0
Updated the method used to determine whether events occur from set pieces (API Events v9.0.0 / CSV Events v9.0.0). The new model tracks player positioning to identify when a set-piece phase has truly ended, rather than relying solely on ball position. A new set_piece_phase field (1 or
2) is included in events that are part of set-piece play.
Attacking Direction
attacking_direction added to events with a team_id, indicating whether the team is playing right-to-left or left-to-right relative to the camera (API Events v9.0.0 / CSV Events v9.0.0).
Indirect Free Kick Metrics
New metrics tracking indirect free kick outcomes have been added to:
- API Team Season Stats v3.0.0 - per-game counts, xG, shot ratios, and goal ratios for indirect free kicks (awarded and conceded)
- API Team Match Stats v2.0.0 - match-level equivalents of the above
