Baseball Lineup Optimizer & Run Expectancy Simulator
Model how the Philadelphia Phillies upended 100+ years of baseball dogma by leading off with home run sluggers. Reorder hitters, test sabermetric vs. traditional batting orders, and run a 10,000-game Markov Monte Carlo engine to observe run expectancy and plate appearance distributions.

1. The 100-Year Fallacy of the Leadoff Speedster
For over a century, traditional baseball managers prioritized speedy, slap-hitting contact outfielders in the #1 spot to "steal bases." But sabermetric math proved that batting first guarantees the highest volume of plate appearances (~720-750 PA per year). Wasting those extra 150 plate appearances on a weak hitter costs dozens of runs over a full season.
2. Why Kyle Schwarber Works at Leadoff
Kyle Schwarber hits .200 to .240 with 150+ strikeouts, yet Philadelphia manager Rob Thomson locked him at leadoff. Why? His elite walk rate gives him a .365+ On-Base Percentage, and his 40-homer pop gives the Phillies immediate 1-0 leads, forcing opposing starters into high-stress first innings.
3. The Modern #2 and #4 Power Clustering
Sabermetric research demonstrated that the #2 hitter comes to the plate in higher leverage than the #3 hitter, and the #4 hitter hits with the most runners on base. The Phillies optimize by clustering Trea Turner and Bryce Harper immediately behind Schwarber, converting high OBP directly into runs.
