MLB Lineup Optimizer

MatchWiz's MLB lineup optimizer is free and built on our own daily fantasy point projections — the same ones we grade against real box-score results in the open, so you can see the track record instead of trusting a black box. It builds cap-legal DraftKings Classic lineups, supports stacking, player locks/excludes, and exposure limits, and exports straight to a DraftKings CSV.

It maximizes our projected DraftKings fantasy points under the $50,000 salary cap and the Classic roster rules (2 P, C, 1B, 2B, 3B, SS, 3 OF), using each player's multi-position eligibility. The two pitchers always come from different games, and stacks take four or more hitters from a high-scoring team. You can auto-generate a set of diverse lineups or build one by hand and let the optimizer fill the rest.

Stacking means rostering several hitters from the same team so their runs, RBIs, and home runs compound in one big inning — the core tournament (GPP) strategy in baseball. Our optimizer ranks teams by projected runs and can lock four or five hitters from a team while automatically avoiding the opposing starting pitcher.

Cash lineups favor safe, high-floor players to reliably beat about half the field; tournament lineups chase upside with stacking and more player diversity to win top-heavy prizes. Our strategy presets set the optimizer for each: Cash weights consistency, GPP leans into stacks and spreads your exposure across a set of lineups.

Yes. Every lineup exports to a DraftKings-format CSV you can bulk-upload to your contest entries. The manual builder and the auto-generate tab both support it.
