or
Is this a 2 piece or one piece bat? Barry
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is a one piece composite bat.
Logan
How does this bat compare to the 2018 Louisville Slugger Catalyst -12 Senior League Baseball Bat: WTLSLCT18X12? What is the difference in the composite material? ax
Both the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 and the 2018 Louisville Slugger Catalyst -12 Senior League Baseball Bat: WTLSLCT18X12 are one-piece composite bats with balanced swing weights. The Prime ONE, in theory, should have a more balanced swing weight due to the SBC end cap and microform composite barrel design.
Cameron
How does this bat compare to the Easton Ghost X -12? Also, what size would recommend for a 9 yr old (54 inches and 62 pounds)? Cdnballplayer
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is similar to the Easton Ghost X -12 bat in that both are one-piece all composite with a balanced swing weight and 2 3/4" barrel diameter. Per your player's height and weight, we would recommend getting a 29 inch model.
Cameron
Does the 919 -12 USSSA bat have a smaller barrel than the 919 -10 USSSA and 619 -10 USSA bats? j35
The barrel diameter of all these models is 2 3/4" in diameter.
Kyle J.
Does the 919 -12 USSSA bat have a smaller barrel profile/sweet spot than the 919 -10 USSSA and 619 -10 USSSA bats? (not diameter which is listed in the description) Are they the same from the end of the bat to where it starts to curve inward? J35
The Louisville Slugger Prime 919 -10 USSSA Baseball Bat: WTLSLP919X10 will have a slightly longer barrel at the same bat length than the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 just due to the amount of material that can be used on a heavier -10 vs. a -12.
Logan
Can my son use this bat when it is cold? Melinda
The composite barrel of the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 can experience issues in colder weather, temperatures 55-60 degrees or below. We suggest limiting this bat in colder weather to just your player and in game only.
Daveron
I am choosing between this bat and the CAT8. I was thinking this bat because of -12 for faster bat speed. He is on smaller side. He is 9, 4’4’’ and 62 lbs.What are your thoughts? Drew
Based on his age and size, I do think it would be a better choice to get the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 as it sounds like he needs a lighter bat to help with swing speed.
Tori
Is this a good coach pitch bat? shawn
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 can be used for Coach Pitch; however, it is intended for the faster velocity of kid pitch. A coach pitch option would be a Junior Big Barrel, like the Louisville Slugger Omaha 518 -10 Junior Big Barrel Baseball Bat: WTLSLO518J10.
Daveron
I have a 9 year old @ 4'9" & 105 lbs. He is moving up from Ghost X Hyperlite (29"/17 oz). How does the 919 compare to 2018 CF Zen? Recommended length/drop? Cody
Based on your player's height and weight, I would recommend getting a bat in the 30" length. This Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat (WTLSLP119X12) will definitely be lighter than the CF Zen as this Prime ONE has a -12 sizing. The Zen is -10 at the lightest. If you were wanting to move him to something a little heavier and allow for more progression in regard to bat size, the ZEN is the way to go. However, if you want to make the most gradual jump from a 29"/17 oz size to a 30"/18 oz size, this Prime ONE would be the bat to purchase.
Ben
Does this bat need to be broken in? Thanks Randy
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 features a composite barrel. We suggest all composite barrels to be broken in before they see live pitching. Generally, 150-200 swings off a tee, rotating the bat every 10 swings will accomplish this.
Daveron
I was wondering what the difference is between from the PRIME ONE vs Solo 619? Jadin
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is a one-piece all composite bat while the Solo 619 Louisville Slugger Solo 619 -10 USSSA Baseball Bat: WTLSLS619X10 is a one-piece alloy bat. Both bats are balanced but the Solo 619 is two ounces heavier. As well, the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is best suited for players between the ages of 6-10.
Cameron
Is this bat designed for 9u travel ball? Kyle
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is approved for travel ball. The -12 option is a good length to weight distribution for 9U players.
Daveron
I’m interested in this bat for my son, but I have heard that USSSA bats will be outlawed in 2020. Wanted to ask if you all knew anything about that. He plays in a USSSA rec league and in local USSSA tournaments. Brett
We have not heard anything regarding USSSA bats and them being outlawed in 2020. Your local league may put bats regulations in place that may make the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 illegal to use but we have not heard of anything from a nationwide standpoint renegading the use of USSSA bats.
Cameron
Which bat is the best? CAT Composite, Louisville Slugger Prime ONE -12 or the Easton Ghost X Evolution USSSA? Bryce Bartels
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is going to be lighter, by two ounces, when compared to the Marucci CAT 8 Composite -10 USSSA Baseball Bat: MSBCCP10 and the Easton Ghost X Evolution -10 USSSA Baseball Bat: SL19GXE108. All are good bats but the Prime ONE is best suited for someone around the ages of 6-10.
Cameron
What’s the difference between the Easton Ghost X Hyperlite and the Louisville Slugger Prime One? Mr.Baseball
Both models are one-piece, composite designs that offer a very light -12 drop to them. The biggest difference will be that the Louisville Slugger Prime ONE is offered in more sizes than the Easton Ghost X Hyperlite at this time, and has Louisville's SBC endcap for improved control.
Kyle
What size do you recommend for a 9 year old who is 53" tall, and weighs 65 lbs? Andy Mitchell
Per the player's height and weight, we would recommend getting the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 in a 29 inch model.
Cameron
My son is struggling at the plate with the CAT8 30 in. drop 10. Not sure if the bat has anything to do with it, but was thinking bat speed may be improved with this Louisville prime One. He plays 12 u baseball and is small for his age. Would you recommend this bat for a line drive hitter that is small for his age? Darren
I think the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 will be slightly more balanced and lighter in weight both which could be beneficial. However, I also think getting a two-piece bat might help since it offers more flex in the barrel and can help with swing speed.
Tori
We have been looking at various -12 bats for our son who is 7 and is 4'6" and just over 70 lbs. After looking through them I am hoping you can tell me how a one piece composite, such as this bat, compare to a two piece composite, like the Rawlings Quatro Pro for example, in terms of performance, swing weight, feel, etc. Thank you in advance. Jeff Pullam
One-piece bats like Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 will have a little bit of a stiffer feel on contact. This can help create more power behind the ball. A two-piece bat like the Rawlings Quatro, will offer more flex in the swing which can help with swing speed. It can also help break up the vibration.
Tori
My son is 4’8” and around 87 lbs. U10 going into U11 come next season. What size would you recommend? Ron
Per your son's height and weight, we would recommend getting the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 in a 29 inch 17 ounce size.
Cameron
What is the vibration of this bat compared to Marucci CAT 8? Richard Bouris
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 does not feature any vibration technology like the Marucci CAT 8 (AV2 knob reduces vibration on that bat). Thus, if a player does not square the ball up on the barrel they will feel vibration or stinging of the hands.
Cameron
I have a 9 year boy that is 50" tall and 45 lbs. He had a Rawlings Threat bat before but it stung his hands a lot. Is this a good bat for him or would you recommend the Cat 8? David
Based on your player's height and weight, I would recommend a 28" bat. In regard to getting this Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat (WTLSLP119X12) or the Cat 8, you might have to decide if you prefer a -12 sized bat or a -10 sized bat. This bat will weigh 16 ounces at the 28" length. The Cat 8 will weigh 18 ounces at the 28" length. Both bats will perform well, it will just come down to deciding which weight will fit your player best.
Ben
I'm debating between this bat and the -10 Prime for a 10u kid who is 56" tall and roughly 75lbs. He is playing AA/AAA ball. Would you recommend the -10 bat? Parent
A -10 is the much more common drop for a 10U player, but if the player can't handle a bat that heavy then the -12 would be better.
Kyle
How does this bat's barrel size length, where it tapers down, compare to the Marucci CAT 7? Jared
It is hard to compare the barrel taper of the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 to that of the Marucci CAT 7. With that being said, one will most likely see a more gradual, or even barrel taper, on the CAT 7.
Cameron
For travel ball, does barrel size matter? Or as long as it has the USSSA cert stamp it can be used in all travel ball? Patrick
Generally speaking, USSSA games and tournaments rarely have restrictions with regards to barrel diameter. The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: bat will feature in the -12 and -10 drop options.
Cameron
My grandson is 62 " tall and weighs 150. He is going in to 11u this spring Is this a good bat for him. what size do you recommend? Mike nelson
Based on his height and weight, I would recommend a 32''. The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is probably too light for him. I would recommend looking at a -10 like the Louisville Slugger Prime -10 USSSA Baseball Bat: WTLSLP9X1020.
Tori
Is this bat allowed in Little League (U10)? I believe only USA Baseball certified bats are allowed in LL while USSSA bats are not. Is this correct? Sig
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is not allowed for use in Little League as only USA Baseball certified bats can be used.
Cameron
My son is 9 and currently uses a CAT 7 26 inch 16 oz bat. He plays travel ball in the spring and fall. Would this be a better bat for him? I’m thinking either the 28 inch or 29 inch. Colt Lipsey
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is a good bat for a player 10 or younger. Since your son has been using a drop 10 bat previously, you may want to consider using a heavier bat.
Cameron
Is there a break in period for this bat? Blake
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is hot out of the wrapper but it is never a bad idea to put a composite bat through a slight break in of 75-150 pitches. This would consist of tee work, soft toss, front side toss, etc at around 70% max effort. After a set of ten swings, rotate the bat a 1/4 turn.
Cameron
My son is 9. He's 4'10" 115LBs. He's currently swinging a 30in 19oz Easton Ghost Hyperlite USAbat. I'd like to get him a USSSA bat for AAU. Should I go with 31in 19oz or 30in 18oz? Scott
Based on the height and weight you listed, I would suggest sticking with that 30in bat length. The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is a great option for him, the build of this bat is very similar to the one he is swinging now. (Easton Ghost X Hyperlite)
Ryan
My son is 8 1/2 years old, 4’1" and 54 pounds. He tried a friend's Louisville Slugger Prime One 15 oz, 27 inches, 2 3/4 barrel and it seemed to work great. Before I purchase do you agree on oz and inches for his height and weight? Melissa
For a player that is 8.5 years old, 4'1" and 54 lbs, we would recommend a 28 inch model of the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12. If you feel the 27 inch is better suited for him, then there is certainly nothing wrong with utilizing that size.
Cameron
My son is 7 1/2 years old, 60lbs and plays on two different teams one is kid pitch, one is machine pitch 9U. Currently his bat is in Easton 25 in -11 drop 14 ounce. What size do you think you should get? The 27 inch 26oz -12 drop is what I was leaning towards, but uncertain. Thank you! Jennifer
Based on his age and weight, I think getting the Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 in a 27'' would be appropriate.
Tori
What year is this bat Amber King
This Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 is a 2019 model.
Ryan
My son is currently 5’0” tall and about 85 lbs. (age 11). Will turn 12 in May during next spring season. Was thinking of getting him a 31” Prime One for next spring. Would this be a suitable bat for him. Worried with drop -12 it will be too light. He is tall and thin, not a big power hitter, more of a contact hitter. Gary B.
The Louisville Slugger Prime ONE 919 -12 USSSA Baseball Bat: WTLSLP119X12 might be a little light for him. I would recommend moving him up to a -10 with a balanced swing feel. The Louisville Slugger Solo -10 USSSA Baseball Bat: WTLSLS6X1020 would be a great bat to make this transition as it is very balanced and will help him get used to the weight.

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.
