The S318 is a medium-barrel bat with a dramatic transition from barrel to handle. It has a traditional, slight knob taper and its short barrel-to-handle taper helps create its end-loaded feel.
It registers as a '4' (Slightly End Loaded) on the Swing Weight Scale.
This model is made with Maple, which is the species preferred by more than 70 percent of Major League players. Maple bats are known for their surface hardness, unmatched sound and solid feel upon contact. The closed grain structure of the Maple wood lends itself to a more durable surface strength and stiffer feel. It has been stamped with an Ink Dot to indicate the highest quality wood bat, meeting slope-of-grain standards for play in Major League Baseball.
New to the 2020 line, easy-to-read medallions have been embedded in the knob, clearly show the identifying characteristics of your bat and replacing outdated etching that has been previously used. The medallion indicates the MLB Prime grade of wood, the species and the length, while the bat name is engraved in the surrounding area.
Louisville Slugger’s exclusive Seamless Decals are applied directly under the top coat, giving MLB Prime bats a pristine look. All MLB Prime models feature branding that blends into the bat almost as intricately as the grain of the wood itself – without added stress from pressure and heat. Thanks to this innovative technology, MLB Prime bats continue to shine after countless trips to the plate.
A new condensed appearance adds the finishing touch to the completely re-designed 2020 MLB Prime lineup, giving these bats an even cleaner, high-end look.
Our completely re-engineered Craftsman-Style Cup features a thicker width edge along the end of the barrel, lending added strength and durability to the end of the bat to help reduce chipping and cracking.
The 2020 MLB Prime lineup features the revolutionary new EXOPRO finish that’s twice as hard as the previous EXOARMOR. This latest innovation in wood bat technology gives you a finish you can feel in an incredibly durable top coat that not only drastically increases surface hardness, but gives you a mirror-like finish in high-gloss models, elevating the color and grain definition of the bat. EXOPRO delivers what you’ve always wanted – a wood bat that feels as good as it looks.
MLB Ink Dot
The Ink Dot is the stamp of the highest quality wood bat. Louisville Slugger ink-dotted bats that meet slope-of-grain are approved for play in Major League Baseball. Every Maple and Birch Louisville PRIME bat carries this stamp of approval (Ash bats do not have the Ink Dot, since their grains are easily visible).
