Why Execs Picked the Padres
In high-profile executive polls, baseball insiders repeatedly singled out San Diego as October's most dangerous club. The quantitative reasoning centers on two postseason super-factors:
- Relief Strikeout Dominance: High-K bullpens eliminate balls in play and BABIP uncertainty during tight 7th, 8th, and 9th innings.
- Short-Series Pitching Leverage: In October, off-days allow managers to compress rotation starts into top frontline aces (Cease, King, Musgrove, Darvish) rather than relying on back-of-the-rotation starters.
Simulation Engine Formula
Each individual game is modeled via Log5 probability factoring team true-talent baseline wOBA/FIP, adjusted for starting pitcher quality, bullpen leverage tier, and home field edge:
P(A beats B) = (pA - pA·pB) / (pA + pB - 2·pA·pB) + HomeEdge + Noise
Series are contested under official MLB formats: Best-of-3 Wild Card (all at high seed), Best-of-5 Division Series (2-2-1), and Best-of-7 League Championship and World Series (2-3-2).
