Very Good Bat for big hitters Smith parent

Pros: We needed a second bat and decided to give it a try. Only a week in but this bat seems just as hot as the 718 -5. Very impressed with this bat and it far exceeds the current competition with maybe an exception of the 718. Jury is out on which may be the best power bat for big sluggers for 2018 in our opinion, but my son loves it and has not complained at all about not swinging his 718 or prior Ghost Comp bat.

Cons: Cap design doesn't sound tight. Jury is out on durability and vibration if your son is not consistent at finding the sweet spot and staying through the ball. For that I'd rate it 2nd best behind the 718.

Questions and Answers (7)

Have a question about the Mizuno MAXCOR -5 USA Baseball Bat: YBB5MAX? Ask our team of experts and they will respond within 24 hours.

Is this a one piece bat or a 2 piece bat?
The 2018 Mizuno MAXCOR -5 USA Baseball Bat: YBB5MAX is a two-piece model.
What is the availability of this bat? In stock? Any reviews for this bat? Hard to find any feedback.
We have the 2018 Mizuno MAXCOR -5 USA Baseball Bat: YBB5MAX available in three different lengths. This bat was released in October which is why there aren't that many reviews on this model.
Why is this bat so costly in comparison with other two piece (Hybrid/Alloy) bats? Is it the sleeve on the barrel?
I would imagine that the 2018 Mizuno MAXCOR -5 USA Baseball Bat: YBB5MAX is priced due to its long barrel, the dynamic damper connection piece to limit vibrations, and the Viscoelastic Polyurethane (VP) Sleeve to improve performance. However, we do not set the price on this bat that would be Mizuno so for more information on the pricing of the bat I would recommend reaching out to them at (800) 966-1211.
Is this bat legal in a Cal Ripken sanctioned tournament?
Billy ball
This bat has the USA certification stamp so it would be legal for play in a Cal Ripken tournament.
Kyle J.
Is this considered a balanced bat, or an end-loaded bat? On one youth bat review website where it was tested it was described as end-loaded; but in the production description here it says "balanced".
The 2018 Mizuno MAXCOR -5 USA Baseball Bat: YBB5MAX is a balanced bat in design. The actual weight does tend to be about 0.5 ounces heavier than the listed weight. This may be why it was described as end loaded.
I wish this bat was available in a 33" length. Is it?
fred a kopp
We do not carry this bat in a 33" length. I would contact Mizuno directly to see if they even make it in a 33" size.
Kyle J.
Why is this bat discontinued? Was or is there a recall?
Bat manufacturers move on to the next model in a line quickly. Therefore, Mizuno has stopped producing the 2018 Mizuno MAXCOR -5 USA Baseball Bat: YBB5MAX as they focus on their 2019 lines.
