Win Probability
Red Sox 30%
70% Cubs

The Cubs have a strong edge because their offense, lineup and platoon matchups and defense are stronger overall.

Why 70%?

Low confidence. 6 of 15 model categories are currently supported by data.

Offense Cubs edge · 31% applied

The away club has a strong edge in offense (113 vs 100 wRC+).

Cubs: 113 wRC+ Red Sox: 100 wRC+
  • Team wRC+ (away) 113 MLB Stats API
  • Team wRC+ (home) 100 MLB Stats API
  • Team OPS (away) .765 MLB Stats API
  • Team OPS (home) .717 MLB Stats API

  • Runs per game (home) 4.27 MLB Stats API
  • Hard-hit % (away) Unavailable MLB Stats API
  • Hard-hit % (home) Unavailable MLB Stats API
Starting Pitcher Unavailable

One or both probable starters have no stat line yet.

Bullpen Unavailable

Bullpen splits have not been imported for both clubs.

Lineup / Platoon Cubs edge · 16% applied

The away club has a strong edge in platoon matchups (.793 vs .733 OPS in their stronger split). Starter handedness and confirmed lineups are not wired up, so this is a club-level split rather than a true lineup-versus-starter read.

Cubs: .793 OPS Red Sox: .733 OPS
  • OPS vs LHP (away) .793 MLB Stats API
  • OPS vs RHP (away) .756 MLB Stats API
  • OPS vs LHP (home) .733 MLB Stats API
  • OPS vs RHP (home) .711 MLB Stats API
  • Confirmed lineup Unavailable
  • Platoon advantage count Unavailable
  • WAR missing from lineup Unavailable
Pitch-Type Matchup Unavailable

Pitch usage and hitter results by pitch type are not in the daily snapshot yet, so this category is not scored.

Defense Cubs edge · 16% applied

The away club has a strong edge in defense (.727 vs .708 defensive efficiency). DRS and UZR have no free public source and are left out rather than estimated.

Cubs: .727 Red Sox: .708
  • Defensive efficiency (away) .727 MLB Stats API
  • Defensive efficiency (home) .708 MLB Stats API
  • Outs Above Average (away) 71 MLB Stats API
  • Outs Above Average (home) 20 MLB Stats API
  • Defensive Runs Saved Unavailable
  • UZR Unavailable
Baserunning Unavailable

Needs full player-level import for both clubs; only teams with individual hitter snapshots roll up to a team baserunning total.

Recent Form Red Sox edge · 18% applied

The home club has a clear edge in recent form (4-6 vs 5-5 over ten games). Ten games is a small sample, which is why this is weighted lightly.

Cubs: 4-6 Red Sox: 5-5
  • Last 10 (away) 4-6 MLB Stats API

  • Streak (away) L2 MLB Stats API
  • Streak (home) W2 MLB Stats API
Ballpark Fit Cubs edge · 16% applied

Fenway Park suppresses home runs (95 home run factor). The away club has a slight edge in how this park suits them (.180 vs .150 ISO).

Cubs: 104 runs Red Sox: 95 HR
  • Run park factor 104 MLB park-factor baseline (multi-year estimate)
  • Home run park factor 95 MLB park-factor baseline (multi-year estimate)
  • Double park factor 117 MLB park-factor baseline (multi-year estimate)
  • Team ISO (away) .180 MLB Stats API
  • Team ISO (home) .150 MLB Stats API
Weather Unavailable

No weather feed is wired up, so temperature, wind and carry are not scored.

Rest / Fatigue Unavailable

Travel, days rest and schedule density are not tracked yet.

Injuries Unavailable

There is no injured-list feed, so missing WAR is not scored.

Historical Calibration Red Sox edge · 4% applied

Judged against how this season has actually gone, the rest of the model looks a little low on the home club, by about 11 points. That read is backtested over 52 completed games at 56% accuracy.

Cubs: -11 pts Red Sox: +11 pts
  • Backtest sample size 52 games NumSOX backtest
  • Backtest accuracy 55.8% NumSOX backtest
  • Brier score 0.254 NumSOX backtest
  • Calibration adjustment +11 pts to the Red Sox NumSOX backtest
Regression Risk Unavailable

Needs ERA and FIP for both starters to compare surface results with fielding-independent ones.

Live Game State Unavailable

The game has not started, so score, inning and base state carry no weight yet.

Data Sources & Freshness Source dates by statistic

Each supporting statistic above carries its source and latest available update date. Missing feeds are marked unavailable and do not receive model weight.

Estimate generated Sep 26, 2026 4:34 PM.

This is a custom NumSOX estimate based on baseball statistics, not a betting line or a prediction of certainty.
