What the optimizer does
A new slate every day
MLB runs daily. Main and single-game slates load with our projections and salaries ready to optimize.
Projections that stay current
Our projections refresh several times a day through the season, so you're not optimizing on stale morning numbers.
Team stacks and hitter caps
Set a primary stack and cap hitters per team. The optimizer keeps every lineup roster-legal on DraftKings and FanDuel.
Locks, exclusions, exposure
Lock your pitcher, exclude anyone you don't trust, and cap exposure across a full lineup set before you re-run.
