- Avoid pairing a pitcher with the hitters he is facing.
- Top of the batting order means more plate appearances, which matters in a single game.
MLB Showdown questions
Is MLB Showdown available now?
MLB Showdown is in the off-season and returns for the 2027 season. NFL and NBA Showdown are live now, and every plan will include MLB when it returns.
What is an MLB Showdown optimizer?
A tool that builds DraftKings Showdown lineups for a single MLB game: one Captain at 1.5x salary and points and five UTIL players under the $50,000 cap.
What makes MLB Showdown different?
Hitters on the same team are strongly correlated, and pitchers work against the opposing hitters, so stacks and pitcher-vs-hitter rules matter more than in other sports.
Projections, simulations and ownership are model estimates for comparing lineups, not predictions or promises of results. 18+. Play responsibly.
