Description

Louisville Slugger Kryo ONE -11 Fastpitch Softball Bat: WBL4272010

Make waves from your first swing with the Louisville Slugger Kryo One™ (-11), a fastpitch softball bat purposefully engineered for elite slap hitters, contact-oriented players, and emerging travel ball athletes looking to make an instant impact. Built around an ultra-balanced weight distribution, the Kryo One swings significantly lighter through the zone than standard two-piece models, empowering younger or developing hitters to generate maximum bat speed and maintain precise control over the entire barrel.

Bat Benefits

At the core of this bat is the Kryo One GO-EX+ composite barrel system, featuring a gapped-wall construction that maximizes wall trampoline right out of the wrapper without requiring an extensive break-in period. To match that power with exceptional control, Louisville Slugger integrated a stiff, one-piece construction with a specialized Tuned Mass Damper (TMD) embedded in the handle. This setup effectively absorbs harsh vibrations on off-center contact while preserving vital feedback so players know where they made contact. Finished with the XPND Performance End Cap and a Premium LS Pro Comfort Grip™, the shortest lengths of the Kryo One -11 are specifically optimized to help rising talent square up pitches consistently and drive the ball into the gaps.

Warranty

The high-powered bats of Louisville Slugger are backed by a twelve (12) month manufacturer's warranty! If you have bought this bat from us and noticed that there is an issue on it before 12 months have passed from the purchase, please reach out to our Bat Experts. They will be able to get you the necessary information to reach out to Louisville Slugger and begin the warranty replacement process.

About the Brand

In 1842, J. Frederick Hillerich emigrated with his family from Baden-Baden, Germany to the United States. Eight years before, the 1834 Book of Sports had made its debut as the nation's first publication covering baseball. But when he arrived in Baltimore, J. Frederick Hillerich would never have dreamed of the future impact his family would have on America's favorite pastime.

After a short while, the Hillerichs moved to Louisville, where J. Fred started a woodworking shop in 1856. Two of his sons, Adam and John Andrew "Bud" were born in the United States and would later join their father in his business. By 1864 "J.F. Hillerich, Job Turning" was in operation and filled orders for businesses by custom-turning everything from balusters to bedposts.

The firm thrived, and by 1875 the little woodworking shop employed about 20 people. In 1880 Bud Hillerich, who was an amateur baseball player, became an apprentice in his father's shop. Young Bud made his own baseball bats along with bats for several of his teammates.

The debate over the origins of the first bat continues to generate controversy among baseball enthusiasts, but the younger Hillerich was most certainly involved in getting his father's business involved with what would become the company's signature item. According to company legend, the first bat was turned by Bud for Pete "The Old Gladiator" Browning in 1884. Browning was a star on Louisville's professional American Association team - the Eclipse. On a spring afternoon Bud, then seventeen, witnessed Browning break his favorite bat. Bud offered to make a bat for his hero, and Browning accepted. After the young wood shop apprentice lathed a quality stick from white ash, according to the story, Browning got three hits with it in the next game.

Louisville Slugger gloves are worn by more pitchers in Major League Baseball than any other glove.
