Mizuno’s slowpitch lineup has gone from an afterthought to a line of player signature bats in two seasons, and the Logan Rogers is the newest name on a barrel. The 2026 Mizuno Logan Rogers 12.5 inch End Loaded, model 340727, is Rogers’ signature USSSA bat, and it fills the gap between Mizuno’s two other 2026 signature models: the 13 inch Crush (Andy Purcell) and the 12 inch Lambright (Terry Lambright). It’s a two-piece composite with a 12.5 inch barrel and a half ounce end load, which makes it the middle ground, more barrel than the Lambright and a quicker swing than the Crush, built for the power hitter who wants barrel presence and a smooth feel without a slow, heavy swing. It wears a royal blue barrel and handle with Rogers’ name in red down the barrel, a red end cap, and a white grip and taper, which makes it the loudest-looking Mizuno in the rack and easy to spot in a bag. It’s approved for USSSA, NSA, and ISA play, so this is a tournament and open-league bat, not a USA/ASA rec bat.
Mizuno built its slowpitch bats around one composite, and it’s the right one. Black Onyx Carbon is Mizuno’s premium carbon fiber composite, designed for durability and an elite blend of feel, sound, and performance, and on the Rogers it’s laid up in a Triple Wall barrel, three composite layers working together to enlarge the sweet spot and deliver strong performance across the hitting surface. Cylinder Seaming is Mizuno’s barrel manufacturing process, which keeps the wall consistent around the circumference so the barrel performs the same no matter which side you rotate to, and holds up over a season of hard contact. The half ounce end load shifts mass toward the barrel end for more momentum through the zone and more force at contact, and on a 12.5 inch barrel that load stays manageable, which is the whole point of the length: enough hitting surface to forgive a slightly off-center cut, short enough to keep the end load whippy. The two-piece construction joins that barrel to the handle so the barrel can flex and load through contact while the handle stays under control, and Mizuno’s Dual Frequency Damper at the connection combines two materials to absorb vibration on mishits and manage that flex, so a jam shot doesn’t ring your hands and the barrel stays stiff where it should. The Speed-Helix Grip finishes the handle with a comfortable, durable wrap. The barrel is 2-1/4 inches. Approved for USSSA, NSA, and ISA, available in 34 inch lengths at 25, 26, and 27 ounces, and backed by Mizuno’s one year warranty against defects in materials and workmanship.
Mizuno is the newest serious player in slowpitch, which means a lot of hitters are swinging one for the first time, and a shop that’s actually swung them is worth more than one that’s just stocked them.

QUESTION: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
ANSWER: If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits and adds 2-3 business days of lead time to your order. This process is undetectable, but if you plan to use the bat in an official game or event, you should verify legality with your league or sanctioning body. We (LongballBats.com) do not encourage the use of a Heat Rolled bat in any game or event where it is against the rules. The vast majority of new bats that we sell are Heat Rolled with Progressive Pressure. Click here for details about our process!
QUESTION: How does the Logan Rogers compare to the Mizuno Crush and the Mizuno Lambright?
ANSWER: Barrel length is the difference, because the three share the same guts. The Crush, Andy Purcell’s signature bat, is the 13 inch; the Lambright, Terry Lambright’s, is the 12 inch; the Rogers splits them at 12.5. All three are Black Onyx Carbon with the Triple Wall barrel, Cylinder Seaming, the Dual Frequency Damper, a half ounce end load, and USSSA, NSA, and ISA approval. So the question is how much barrel you want! The 13 inch Crush gives you the most hitting surface and the most forgiveness, and it carries the end load the farthest from your hands, so it swings the heaviest of the three. The 12 inch Lambright concentrates the load into the tightest zone for the quickest swing and rewards a hitter who finds the barrel every time. The Rogers is for the hitter who wants more barrel than the Lambright without the Crush’s swing weight, which describes a lot of strong hitters who’ve found a 13 inch end load a step slow and a 12 inch a step small. If you’re between the Crush and the Rogers, pick by how your bat speed holds up late in a tournament; if you’re between the Rogers and the Lambright, pick by how consistently you square the ball up.
QUESTION: What is Mizuno’s Black Onyx Carbon, and how does the Triple Wall barrel work?
ANSWER: Black Onyx Carbon is the premium carbon fiber composite Mizuno uses across its top bats, chosen for the balance of feel, sound, performance, and durability that a composite slowpitch barrel has to hit at the same time. On the Rogers it’s built into a Triple Wall barrel: three composite walls stacked so that each one flexes and recovers at contact, which spreads the barrel’s response over a wider area than a single or double wall and gives the bat its large sweet spot. Cylinder Seaming is the manufacturing step that makes that work. It’s Mizuno’s process for keeping the composite wall consistent all the way around the barrel’s circumference, so there’s no thin side or thick side, the bat performs the same on every rotation, and the barrel holds up instead of developing a soft spot. The practical result for a hitter is a barrel that forgives contact an inch off center and keeps doing it deep into the season, which matters on an end-loaded bat where you’re swinging hard and not every cut is perfect.
QUESTION: Who should swing a 12.5 inch half ounce end load?
ANSWER: A hitter with good bat speed who wants more carry and still wants to feel quick. A half ounce is the lighter of the common slowpitch end loads, enough to add momentum and force at contact without the sluggish feel of a full ounce, and on a 12.5 inch barrel it stays close enough to the hands that most strong hitters can get it through the zone on time. The Rogers suits a power or gap hitter who’s been swinging a balanced bat and wants a step toward more pop, or a hitter who’s found a 13 inch end load a touch slow and wants the same load on a quicker barrel. It’s not the bat for a hitter who’s still hunting for the barrel or who gets all his power from bat speed; for him, a balanced 13 inch or a 12 inch like the Lambright is the better fit. If you’ve got the swing for it, the Rogers gives you the Mizuno barrel with the load and the length most USSSA power hitters end up wanting.
QUESTION: Is the Logan Rogers legal in USSSA, USA/ASA, and NSA?
ANSWER: USSSA, NSA, and ISA, yes; USA Softball, no. The Rogers carries the USSSA stamp along with NSA and ISA approvals, which covers the big tournament circuits and most open adult leagues. It is not stamped for USA Softball (ASA), so it won’t pass a bat check in a USA league or a rec league that follows the USA Softball list, and that’s the most common mistake with any USSSA slowpitch bat. If you play in both a USA rec league and USSSA tournaments, you’ll need two bats, and we can set you up with a USA-stamped partner for the Rogers. Before any tournament, check the taper for the USSSA stamp and confirm the model against the current approved bat list, since lists get updated. If you’re not sure which stamp your league follows, call us; reading stamps is a big part of what we do!
