2021 Mizuno Hot Metal B21 BBCOR

2021 Mizuno Hot Metal B20 Review

July 8, 2020 | by Brian Duryea | @BatDigest

Despite a lackluster performance at the box office for BBCOR bats, Mizuno continues to pump out good content–especially in the Mizuno Hot Metal series. We’ve hit the 2021 B21 Hot Metal from Mizuno with three different hitters so far. Each is impressed. In particular, to the exit speeds, they can generate when compared to other name brand bats. We spent time with the 33 and 32-inch in BBCOR and write our review of those bats below. In time, USSSA and USA bats might be coming out too, and we’ll add that to our analysis when we get it.

Our hitters loved the exit speeds. The feel on the bat was good, but nothing to write home about. If you hit one off the end cap, you for sure felt it.

Quick Review

Our hitters loved the exit speeds. The feel on the bat was good, but nothing to write home about. If you hit one off the end cap, you for sure felt it. But, that’s the type of feedback some players prefer. In terms of straight exit speeds and overall performance in BBCOR, the B21 performed like highly recommended Rock Star.

Recommendations

It swings on the heavier side. Of all the 33-inch bats we measured in swing weight for 2020, the 9500 score on the B21 puts it in the top 5 of heavy swing weights. (We realize this is a 2021 bat, but at the time of release, it was one of the only 2021s around. So, our reference point, for now, is in the 2020 swing weight realm).

In as much as it is a heavier swinging bat, and the fit is just about everything in BBCOR bats, do know you are getting one that’s a bit more difficult to swing than you might hope. See our full list of BBCOR bat swing weights here.

BBCOR Hot Metal B21 Recommendations
2021 Mizuno Hot Metal B21 Review

We recommend the B21 Mizuno Hot Metal in BBCOR for those who like an end-loaded single piece feel. It’s comparable to the Omaha, and we’d likely prefer the Hot Metal over a bat like the Omaha. If you want to maximize your exit velo and can swing a bigger stick, this bat should be on your shortlist.

USA Hot Metal B21 Recommendations
2021 Mizuno Hot Metal B21 Review

At some point, Mizuno will release more information on its 2021 USA B21 Hot Metal Mizuno bats. For now, we have only hit with the 2021 BBCOR version of the bat. We expect the USA to follow suit, but will get them in hand before we say anything.

USSSA Hot Metal B21 Recommendations
2021 Mizuno Hot Metal B21 Review

At some point, Mizuno will release more information on its 2021 USSSA bats. For now, we have only hit with the 2021 BBCOR version of the bat. We expect the USSSA to follow suit, but will get them in hand before we say anything.

Comparable Bats

There are plenty of single-piece aluminum bats with a big swing on the market today. Off the beaten path, you can find a bat like the Widowmaker from Anderson. In more traditional routes, look for something like the Omaha or 5150 from Rawlings. As well, our hitters like the Bonesaber from Warstic. Each of those bats listed does a great job on top-end exit speeds for those who can wield them well.

Also, the B21 is a lot like a CAT 8. Both have variable wall thickness and use a single piece of aluminum for the entire bat. Of course, the CAT 8 has some sting dampening technology in the handle, but in terms of barrel and performance, we think they are very similar.

2020 Omaha

Compare the Omaha Review

2020 Louisville Slugger Omaha Review: Value. Value. Value. After hitting with every version of the 2020 Slugger Omaha, we are confident it will continue to dominate the value purchase realm of all baseball. It serves as a legit option for novice and expert alike in the BBCOR, USSSA and USA space with a reasonable price point most parents are willing to pay. Our favorite, if we had to choose, is the drop 5 USA Omaha. With the exception of the 33 and 34-inch BBCOR, 2020 Omahas are built with a light swing in mind. Those two BBCOR versions are intentionally built for a heavy swing. Our Score 9.8/10 (BBCOR); 9.5/10(USSSA); 9.8/10 (USA).

2020 Bonesaber

Compare the Bonesaber Review

The Warstic Bonesaber is a BBCOR and USSSA single piece aluminum bat with a unique and much loved tapered handle.

We used three different hitters on the BBCOR Warstic Bonesaber. All think it is one of the best feeling single piece aluminum bats on the market. The tapered handle makes a real difference, and the barrel performance felt as good as any aluminum BBCOR bat on the market. Warstic’s distribution isn’t like other companies, and the price point on the Bonesaber is pushing it. But, if you’re looking for a top-end single piece aluminum bat with a fantastic design and feel, then the Warstic Bonesaber for 2020 deserves all your attention.

2020 CAT 8

Compare the CAT 8 Review

As of now, COVID has pushed the release of the CAT 9 back to August of this year. We aren’t yet privy to how it is upgraded or changed from the CAT 8 but, of course, we are expecting great things. For the last run of the CAT 8, Marucci also updated many of their BBCOR bats throughout 2019 due to the new white bat NCAA ban.

When Marucci CAT 9 is released you can be sure we will review it here.

You will note, the 2020 USA CAT bat is named the 2020 Marucci CAT USA.

Research: 2021 Mizuno Hot Metal B21

2021 Mizuno Hot Metal B20 Review

2021 Hot Metal B21 Construction

The Mizuno B21 Hot Metal is a single-piece aluminum bat made from a single wall of aluminum. The bat wall adjusts it’s thickness as it moves from the center of the bat to its outsides. This helps increase bat performance outside of the dead center of the bat. Several companies, including the CAT 8 from Marucci and Velo from Rawlings, use a similar tactic.
