Ronald Acuna Jr.’s signature series maple baseball bat, Pro Hardened for loud, MVP-caliber contact.

The Pro Prime Signature Series RA13 features a high-gloss black AJ10 handle with a natural I13 barrel and a slightly end-loaded swing weight, exactly what reigning MVP Ronald Acuna Jr. looks for in a bat. An all-new surface hardening process, including our Professional Series Finish paired with UV light treatment, results in bats that are 30% harder than previous Louisville Slugger Prime models.

The Pro Prime RA13 is accompanied by an industry-leading 75-day limited warranty. Restrictions apply. Visit the Limited Warranty page on slugger.com for complete details.

• Seamless Decals: Applied directly under our high-definition topcoat, the iconic center brands and back brands blend into the bat almost as intricately as the grain of the wood itself
• Professional Series Finish: An enhanced resin material, paired with an ultraviolet light finishing process, results in a bat 30% harder than previous Louisville Slugger Prime wood bats with mirror-like appearance on gloss models
• UV Light Treatment: A specialized ultraviolet lamp generates a chemical reaction within the topcoat to immediately cure and harden the material
• Pro Hardened: Steel rods generate a combination of pressure and heat to compress the wood of the bat and create a harder, denser surface along the entire length of the barrel
• 75 Day Limited Warranty: Every new Prime bat features a best-in-class limited warranty that more than doubles our previous 30-day coverage as our mark of confidence in the hardest bats we've ever made.
