Louisville Slugger K100 36" Wood Fungo Bat

The Louisville Slugger K100 is one of the most recognized wood fungo bats in baseball. Built for coaches who spend long practice sessions hitting fly balls and grounders to their players, this 36-inch fungo bat combines a lightweight foam core with performance-grade ash to deliver distance and control without wearing out your arms. Whether you are running infield drills for a youth travel team or shagging fly balls with a college outfield, the K100 gives you a reliable tool that holds up to daily use.

Louisville Slugger has been building fungo bats for decades, and the K100 is their all-purpose model. It is the largest-barreled fungo in the Louisville Slugger lineup, which gives coaches a bigger contact surface and more pop when driving baseballs to the outfield. At the same time, the end-weighted design transfers energy efficiently so you can place the ball exactly where you need it with a controlled, easy swing.

Foam Core Construction for Reduced Weight

The defining feature of the Louisville Slugger K100 fungo bat is its hollow core filled with foam material. Traditional wood bats are solid throughout, which adds weight that becomes a problem after 50, 75, or 100 swings in a single practice. By removing the solid wood core and replacing it with foam, Louisville Slugger brings the swing weight down significantly. The K100 typically weighs in the range of 20 to 26 ounces, which is noticeably lighter than a standard 33- or 34-inch game bat that runs 30 ounces or more. That weight savings translates directly into less arm fatigue over long baseball practice sessions.

Despite the lighter weight, the foam core provides enough internal structure to keep the bat rigid and responsive. You still get a solid feel on contact, and the bat does not flex or feel hollow when driving baseballs into the outfield.

Performance-Grade Ash Wood

The K100 is made from Northern White Ash, which is the most widely used and dependable wood species in baseball bat manufacturing. Ash offers a good combination of hardness, flex, and grain consistency. It has a slightly softer feel on contact compared to maple, which is more comfortable over extended use. The performance-grade classification means Louisville Slugger selects billets that meet their standards for grain straightness and density, giving coaches a bat that performs consistently from the first swing to the last.

The natural finish with a clear topcoat lets the wood grain show through while providing a layer of protection against moisture and surface wear. The iconic black Louisville Slugger logos and vinyl decals give the bat a clean, classic appearance that coaches have trusted for years.

End-Weighted Design for Distance and Control

Fungo bats are purpose-built tools, and the K100's end-weighted barrel is central to how it performs on the baseball field. The weight concentrated toward the end of the bat helps generate momentum through the swing, so you get more distance without swinging harder. This is especially useful for coaches who need to drive baseballs deep into the outfield during fly ball drills. You can swing at 70 or 80 percent effort and still reach the warning track.

For infield work, the end weight is still an advantage. Choking up on the handle a few inches gives you better control for placing short-hop grounders, slow rollers, and sharp one-hoppers right where you want them. The 36-inch length provides enough reach to toss the ball in front of you and make clean contact, which is a key reason this length has remained the standard for baseball fungo bats.

K100 Turning Model

The K100 uses Louisville Slugger's K100 turning model, which is the largest-barreled fungo profile in their lineup. The bigger barrel means a larger sweet spot, giving coaches more room for error when making contact. That matters during fast-paced baseball infield drills when you are hitting dozens of grounders in quick succession. A slightly off-center hit on a wider barrel still produces a usable ground ball, whereas the same mishit on a narrower fungo might result in a pop-up or foul tip that wastes time.

The tradeoff is that the K100 is heavier than Louisville Slugger's other fungo options, such as the MB Flylite series made from poplar. If you prioritize the absolute lightest swing weight and plan to hit mostly fly balls, the Flylite may be a better fit. But for coaches who want one fungo bat that handles both infield grounders and outfield fly balls effectively, the K100 is the all-purpose choice.

Who This Baseball Fungo Bat Is For

The Louisville Slugger K100 is built for baseball coaches at every level. Youth coaches, high school assistants, college staff, and travel ball organizers all use fungo bats during daily practice, and the K100 is the go-to option for programs that want a durable, reliable tool without spending on specialty models.

This fungo bat works well for coaches who hit both fly balls and ground balls during practice. If your typical routine includes an infield round followed by outfield fly balls, the K100 handles both tasks without needing to switch bats. It is also a solid choice for coaches who run defensive stations, where one coach may hit grounders to infielders while another hits fly balls simultaneously.

The K100 is a training bat, not a game bat. It is designed for tossed or dropped balls, not live pitching. Using it to face pitched baseballs or hitting it on the ground to shake off dirt will likely crack or break the bat. Treat it as a practice tool and it will hold up well across multiple baseball seasons.

How to Use the Louisville Slugger K100 Fungo Bat

Fungo hitting is a specific skill, and the K100 is designed to make it easier. Here are the most common ways baseball coaches put this bat to work.

Outfield Fly Ball Drills

Hold the bat at the knob, toss the baseball a few feet in front of you, and swing through with a slightly upward path. The end-weighted barrel does most of the work. You should be able to drive baseballs 200 to 250 feet or more with a smooth, controlled swing. Focus on placement rather than distance. Hit to different zones of the outfield to work on your players' routes, communication, and tracking.

Infield Ground Ball Drills

Choke up 3 to 6 inches on the handle for better bat control. Toss the baseball in front of you and hit down through it to create ground balls with realistic speed and hop. The K100's bigger barrel gives you a larger margin for contact, so you can hit sharp one-hoppers, slow rollers, backhand balls, and double-play feeds without constantly mishitting.

Pop Fly and Communication Drills

Use a full swing with a high launch angle to hit pop flies into the infield. This helps baseball infielders work on tracking pop-ups, calling for the ball, and dealing with sun or wind. The K100 makes it easy to vary height and placement.

Soft Toss and Front Toss Drills

Some coaches also use fungo bats for front toss drills when a standard bat is too heavy after a long day. The K100 can serve as a lighter alternative for flipping baseballs into a net or screen during informal batting practice, though it is not built to hit pitched balls at full speed.

What's Included

The Louisville Slugger K100 ships as a single fungo bat, ready to use out of the packaging. No assembly is required. Baseballs are not included. Some coaches choose to add an aftermarket grip wrap for comfort and moisture management during long baseball practices, but the bat comes with a standard handle finish.

Care and Durability

Wood fungo bats are durable when used correctly, but they are not indestructible. Keep these guidelines in mind to get the longest life from your K100.

Store the bat in a dry location, away from extreme heat or cold. Wood bats left in a hot car trunk or exposed to moisture can warp, crack, or delaminate over time. After each baseball practice, wipe off any dirt or debris and store it handle-up in a bat rack or equipment bag.

Rotate the bat a quarter turn between hits. Just like game bats, fungo bats last longer when the grain takes contact from different angles rather than the same spot repeatedly. The Louisville Slugger logo is positioned as a reference point; hitting with the logo facing up or down keeps the strongest grain orientation toward the ball.

Do not use the K100 to hit pitched baseballs, slam the barrel on the ground, or use it in batting cages with machine-pitched balls. These actions put stress on the bat that it is not designed to handle and will likely cause it to crack or break prematurely.

Frequently Asked Questions

How much does the Louisville Slugger K100 fungo bat weigh?

Louisville Slugger does not publish an exact weight for the K100, but it typically falls in the range of 20 to 26 ounces. Manufacturing tolerances and natural wood variation mean each bat will weigh slightly different. The K100 is the heaviest fungo in the Louisville Slugger lineup due to its larger barrel, but it is still significantly lighter than a standard baseball game bat.

Can I use this bat for batting practice against a pitching machine?

No. The K100 is a training fungo bat designed for coaches to hit tossed or self-tossed baseballs during fielding drills. Its thinner handle and foam core are not built to handle the repeated impact of machine-pitched baseballs. Using it against pitched balls will likely break the bat.

Is the K100 good for youth baseball coaches?

Yes. The K100 is a great option for coaches working with youth baseball teams. The lighter swing weight makes it manageable for coaches of all ages and fitness levels, and the larger barrel helps with consistent contact when running fast-paced infield and outfield drills.

What is the difference between the K100 and the Louisville Slugger Flylite fungo?

The K100 is made from ash wood with a foam core and has the largest barrel in the Louisville Slugger fungo lineup. It is heavier than the Flylite and works well for both ground balls and fly balls. The Flylite is made from poplar wood, has a smaller barrel, and is lighter. It is designed primarily for coaches who hit a high volume of fly balls and want the lightest possible swing weight. The K100 is the more versatile all-purpose baseball fungo.

How long will the K100 last?

With proper care and correct use, a wood fungo bat can last multiple baseball seasons. The biggest factors are how many swings you take per practice, whether you rotate the grain, and whether the bat is stored properly between uses. Programs that run daily two-hour practices may go through a fungo bat in one or two seasons. Coaches who practice two or three times a week can often get several seasons from the same bat.

Is this fungo bat suitable for softball coaches?

Yes. Softball coaches frequently use fungo bats for the same infield and outfield drills as baseball coaches. The K100 works with both baseballs and softballs, though the feel and distance will differ slightly due to the larger, heavier softball. It is a practical choice for programs that run both baseball and softball practices.
