Built in honor of Rick Schiffhauer, the 2025 Easton Tantrum NEGOTIATOR 1PC Loaded USSSA Slow Pitch Softball Bat (ESU5NEG1L) is more than just a bat—it’s a power-packed statement of dominance. Featuring a 12.75-inch barrel and 0.5 oz end load, this one-piece monster is designed for players who want instant feedback, max barrel control, and eye-popping power through the zone.
Engineered with G4S G4orce Technology, the barrel delivers triple region barrel flex, meaning it compresses differently across zones for a more dynamic sweet spot. You’ll feel the performance on every swing, with optimized compression that turns hard contact into towering bombs. Paired with the Flex 150 handle, this bat maintains stiffness while giving just the right amount of forgiveness for confident, high-powered cuts.
The bat’s HDK23 carbon fiber material offers elite durability while maintaining the Tantrum’s legacy of consistent, high-level performance. The loaded Optimized Player Weighting puts extra pop right behind the ball, maximizing power at full extension. Finished in a crisp white and purple colorway, this bat is USSSA-certified and ready to send a message with every swing. If you’re ready to hit tanks and take names—this is your Negotiator.

OPTION GUIDE: Should I order this bat stock/untouched or Professionally Broken In?
Brand new baseball and softball bats need to be broken in before they perform to their full potential. Our ProMAX Break-In Service adds 20-40ft of extra distance to your solid hits, improves the durability and longevity of the bat and increases the consistency of your results on solid hits, as well. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a professionally broken in bat in any game or event where it is against the rules.
