Passes played into space behind the defensive line for a teammate to run onto, one of the highest-value pass types due to the high-quality chances they create.
A through ball (or penetrating pass) is a forward pass played into space between or behind the defensive line, timed for a teammate making a run. Successful through balls are among the highest-value actions in football — they break lines, eliminate defenders, and create 1v1 or 1v0 goalscoring situations.
Chance creation models rate through balls as the highest-xA (expected assists) assist type after crosses to the penalty spot. A successful through ball to a player in a 1v1 with the goalkeeper generates approximately 0.4–0.6 xG, far above the average shot xG of 0.1–0.12.
Identifying playmakers who consistently attempt and complete through balls is a key part of modern recruitment. Historically, through ball attempts per 90 is a marker of creative output even for players in teams that do not dominate possession. In betting research, teams with high through ball completion rates in the final third tend to generate more high-quality shots — a useful signal for shot-quality adjusted models.
xG (Expected Goals)
A metric that scores every shot by its probability of resulting in a goal, based on factors like shot location, angle, and assist type.
xA (Expected Assists)
A metric that measures the probability that a pass or cross will result in a goal, weighting each assist opportunity by the xG of the resulting shot.
