Frederick's undead take over for one weekend every October. Two pool games Saturday to seed the field, then single-elimination survival Sunday — win or get eliminated. Champions and runners-up walk away with the legendary zombie bats. The 2026 outbreak is over, and the dates for 2027 are set: October 2–3.
Two days built for baseball. Every team is guaranteed a minimum of three games, weather permitting — no bracket-and-bail.
Two pool-play games Saturday set your seed heading into Sunday. Come out swinging — every run counts toward your bracket position.
Sunday is win-or-go-home. One loss and the horde takes you — survive the bracket and the champion crowns automatically.
A minimum of three games per team, weather permitting. Your squad gets a full weekend of baseball, not a single-and-done trip.
Two umpires and fresh game baseballs are provided for every game. Show up, warm up, and play — the details are handled.
There's a reason teams drive from three states over. Champions and runners-up in every division walk out with the legendary zombie bats — the hardware kids actually keep on the shelf.
Themed events run all weekend long: costumes in the stands, undead flair on the field, and a horror-grunge atmosphere you won't find anywhere else. It's real, competitive baseball wrapped in the best weekend of October.
Awarded to first place and runner-up in every division — the trophy every team is chasing.
