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 Louisville's Professional Series Finish paired with UV light treatment, results in bats that are 30% harder than previous Louisville Slugger Prime models.

- Seamless Decals: Applied directly under Louisville's 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 the previous 30-day coverage as a mark of confidence in the hardest bats Louisville has ever made
