The Mizuno B21-Hot Metal BBCOR is a forgotten bat on the market. It’s a great bat but for some reason no one really talks about it. The B21-Hot Metal is slightly end-weighted but a pretty manageable bat for all hitters.

B21-Hot Metal BBCOR: general impression
While the B21-Hot Metal is a pretty generic looking bat, it performs better than we expected. In the one-piece alloy game, end-loaded bats tend to offer more power. The B21-Hot Metal was able to match some of the more well-known models.
The B21-Hot Metal is a pretty generic bat. It’s a single-wall alloy with a CorTech build. That’s the name that Mizuno chose for the technology that allows the wall of the barrel to have a different thickness. They did that so that they can maximize the barrel compression without increasing the swing weight too much.
What have they changed?
Mizuno really hasn’t changed anything to their build since last year. They use all the same technologies and the same materials.
B21-Hot Metal BBCOR overview
Unfortunately, this is something that you’ll hear a lot when we discuss the B21-Hot Metal. The build is solid but unimpressive. They use a CorTech wall to increase the swing speed. The bat is a one-piece model that officers quality durability and performance.
Mizuno created a no-frills bat that really doesn’t stand out. Hitters say that the bat is “fine but doesn’t offer anything special”. The handle isn’t ergonomic and doesn’t offer any additional padding. The grip isn’t especially tacky to help improve control.
Hitters have stated that the B21-Hot Metal seems to have less vibration and “sting” than a lot of the other models. Because of that, it receives a solid score.
We’ve been able to talk to a few players who have said that this bat holds up pretty well. Unfortunately, the players that use this bat on a regular basis are few and far between. Because Mizuno doesn’t sell a ton of the B21 models, it’s hard to get a really accurate report of its durability.
We spent some time with local hitters who were able to test the bat out for us. It seemed to handle varying speeds well. Some hitters were hitting the ball off the end of the bat pretty consistently. Even with that, the end cap was able to handle everything we were throwing at it.
We love the pricing of this bat. At $200 it is one of the most affordable BBCOR bats on the market. It is the most reasonable option for a family or a person who doesn’t want to break the bank when they go looking for a new bat.
It seems like the price of the B21-Hot Metal actually makes it harder to sell. While that thought seems a bit odd, we can explain.
The B21-Hot Metal is the cheapest BBCOR bat on the market. With that, it seems as though customers believe the concept of “you get what you pay for”. It seems like customers who see the $200 price tag assume that the B21-Hot Metal isn’t a quality bat.
The B21-Hot Metal lives up to its name. We were able to meet up with one of the local high school players for a test. We’re definitely comparing two different models, but he offered to take BP using the 2021 B21-Hot Metal and his own 2020 Meta.
We figured it was worth a shot. When he swung the B21-Hot Metal, it competed with last year’s Meta on every level. His average exit velocity and max exit velocity was actually higher with the B21. His max distance was slightly lower using the B21.
While we understand these are two very different bats, we’re happy to use the comparison so that we can get a taste of just how well the bat performs.
Compared to other BBCOR bats
We were pleasantly surprised with the quality of craftsmanship and the performance from the B21-Hot Metal. It certainly can’t compare to the Easton B5 or the Stinger Nuke, but it holds its own with the rest of the competition.
B21-Hot Metal vs. Marucci CAT9
The CAT9 is a great bat. The CAT9 offers an ergonomic, soft-touch grip which is what really sets it apart from the B21. The CAT9 also offers slightly more pop. While it’s close, we’ll take the CAT9. See our CAT9 BBCOR review
B21-Hot Metal vs. Rawlings 5150
This was one of the more difficult comparisons to make. If you’re keeping score at home, we gave the 5150 a score of 22/25. The B21 comes in at 22/25. So, it’s difficult to make a determination on which bat is better. Ultimately, we have to go with the B21 because it’s priced at $200. The $50 discount is what makes the difference or us.

You’ll note that both of these models are pretty basic, but still offer solid performance. Maybe it’s best for you to go to the local store and take a few swings.
B21-Hot Metal vs. Warstick Bonesaber
The B21 beats out the Bonesaber pretty easily. The Bonesaber opted for an “ultra-thin” grip which really makes it less comfortable for the hitter. The pop is probably comparable, but the feel matters. The grip allows much more vibration into a hitter’s hands. Ultimately, the B21 is a better bat with a much better price tag.
Final verdict on the B21-Hot Metal BBCOR
With all the research and conversations that we’ve had, we believe that the B21-Hot Metal BBCOR really stands out because of pricing. It’s a quality bat but it can’t live up to the elite one-piece alloy models on the market. That being said, it’s a great option at $200.
You can trust that Mizuno is offering you a quality product at a great price. If you’re looking for something to take you to the next level, this bat probably isn’t the bat for you. If you’re looking for a quality bat that will hold up for a season without breaking the bank, it’s a great option.
