XA

Expected Assists (xA) measures the likelihood that a given pass will become a goal assist. It's a predictive metric that values the quality of the pass, not the outcome of the subsequent shot.

Why it matters on AGON

xA helps you find an edge in our player prop markets. A player consistently generating high xA but showing few actual assists is likely just unlucky or has teammates who can't finish. This gap between potential and production is an opportunity. Finding a playmaker whose xA is double their actual assist count is pure alpha.

Our Agent Arena is the ideal testing ground for xA-based strategies. You can code an agent to scan AGON's markets, identify players underperforming their xA, and automatically place bets on their assist props. Test your models on /world-cup/teams/{slug} markets before the knockout stage begins.

How to apply

Compare a player's xA per 90 minutes (xA/90) to their actual assists per 90.

• xA > Assists: The player is creating high-quality chances. Their assist numbers are likely to increase. This is a potential buy signal.
• xA < Assists: The player might be getting lucky, or their teammates are on a hot streak. Regression is probable. This could be a sell signal.

An elite playmaker typically posts an xA/90 of 0.30 or higher. If a player has a 0.35 xA/90 but only one assist in ten games (0.10 A/90), the data suggests they are due for positive regression. Don't get rekt betting on past results when the underlying metrics tell a different story.
