As highlighted by The Athletic and The New York Times, October baseball hinges on extreme team traits. The Phillies lean on Zack Wheeler and Aaron Nola's 3.64 starter ERA, but risk cold stretches from high chase rates. The Astros lead the AL in lowest whiff rate, but face bullpen question marks with starting attrition.
Single-game head-to-head win expectancies use the Bill James Log5 formula adjusted for ace rotation quality, bullpen high-leverage depth, and home field edge. Series probabilities are mapped via binomial probability combinations across Best-of-3, Best-of-5, and Best-of-7 series.
Running 2,500 iterations simulates every possible branch of the bracket including chaotic Wild Card upsets, bye team rust vs. rest dynamics in the Division Series, and pennant matchups to give truthful World Series title probabilities.
