MLB: Highest ABS Challenge Success Rate (Team)

Platform comparison

Market context

The underlying event is the 2026 MLB regular season, where teams compete to achieve the highest percentage of successful automated ball-strike challenges, with the market currently pricing a 36% chance that the outcome will be a "yes" for the leading team. This system, powered by Hawk-Eye technology and introduced for the 2026 season, allows teams to overturn umpire decisions on pitch calls, with early data showing a 61.3% success rate across the first 12 games of the regular season[4].

Historically, comparable cases from spring training and Triple-A seasons suggest that challenge success rates hover near 54%, essentially a coin flip, but with slight variance depending on team strategy and player roles[3][10]. In spring training, only 1.4% of pitches were challenged, aligning with 2025 Triple-A data, indicating that teams are still refining their challenge frequency[3]. The New York Yankees currently lead with a 58.7% success rate on 17 challenges, while the Mets sit at 54.5% on 21 challenges, showing that top performers can sustain rates well above the league average[8].

Traders should monitor upcoming team announcements regarding lineup changes, as injuries or suspensions to key batters or pitchers could alter challenge strategies, and watch for schedule dependencies that may affect the number of challenges issued. Recent rankings from ESPN confirm that team-specific success rates vary significantly, with the Phillies at 48.6% and the Yankees maintaining a clear edge[8]. Additionally, the overturn rate differs by position: catchers face a 64% overturn rate on 92 attempts, while batters and pitchers see 42% and 40% respectively, suggesting that teams with aggressive catching staffs may struggle to maintain high success rates[5].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
