Marucci Block Party End-Loaded Slowpitch Bat USSSA (2026)

ROY'S RATING: 4 stars

BUILT TO SMASH. Inspired by the iconic world of colorful building bricks, this bat delivers power you can assemble swing after swing and is made for players who love to create their own chaos.

Features:

12.75" barrel length

2 1/4" barrel diameter

One-Piece Composite Construction

Barrel modulated stiffness-MST

Mid-Stiff handle

Slightly end-loaded feel – balanced enough for all to swing – dangerous enough to do damage

Disrupt mono barrel technology

Modulated Stiffness Technology (MST) is Marucci's unique system that connects the barrel and handle in a way that fine-tunes how the bat flexes. By adjusting the materials in key areas, MST creates the perfect balance between flex and stiffness -- giving you better energy transfer, control, and feel. The result is a bat that dynamically adapts to the player’s swing, delivering optimized performance at every point of contact.

USSSA, NSA, and ISA certified

1-year manufacturer's warranty

Marucci Block Party End-Loaded Slowpitch Bat USSSA MSPBP1LU (2026)

USSSA Certified Softball Bat

USSSA has used a 1.20 BPF standard in its softball programs for 15 years. The BPF standard was developed by NYU Physics Professor Dr. Richard A. Brandt over 15 years ago. The BPF standard is based on fundamental laws of physics that allow Dr. Brandt's testing lab to measure the relative performance of bats to be used in USSSA play.

Warranties from Bat Manufacturers

At Closeout Bats, we stock what we sell! We have a huge warehouse and are NOT drop shipping bats like many websites. We update inventory and availability on the website several times a day as inventory positions change, shipping hundreds and hundreds of bats. We also sell bats out of our physical store, so sometimes things sell out before we can get them off the website.

Limited quantities available. Prices subject to change without notice. Like we say, if it's on the site, it's in the warehouse -- just SOMETIMES it might have some other player's name on it! If you snooze, you lose, so ORDER YOURS NOW!
