Borderline vs ABSline

Think you can outperform a Major League umpire? Put your eye to the test with real Statcast pitch data — the same technology MLB uses during official ABS challenges. Every pitch in Borderline is a real called pitch from a real MLB game. You see the ball fly in from the pitcher's perspective, and you have to call it: ball or strike. Then the rulebook strike zone appears, and you find out exactly where it landed — and whether the umpire behind the plate got it right. REAL MLB DATA Every pitch comes from Baseball Savant's Statcast database. Real coordinates, real spin rates, real umpires — no simulations. THE ABS STRIKE ZONE Borderline uses MLB's Automated Ball-Strike system rules. If any part of the ball touches the rulebook zone, it's a strike — the same standard used in official ABS challenges. The batter's zone height adjusts dynamically per player. FOUR WAYS TO PLAY Arcade — 10 random borderline pitches. Quick, free, addictive. Daily Challenge — 10 blown calls from yesterday's games.
