Pros:  It feels lighter than a -12 for great bat speed. I take hacks everyday of the week and the bat has no dents or bad marks, it holds up very well. It also, jumps quickly off the bat.

Cons:  The break in process was very long and it had a lot of sting during the process

I just received this bat as a replacement for a bat that was defective, under the year warranty process. The lady said that this bat would meet the standards for Little League play in 2018. It does not have the USA stamp on it that I recall (may have to look at it again). Is this bat a legal bat?

This 2017 Easton MAKO BEAST Youth Baseball Bat (YB17MK12) has USSSA 1.15 BPF certification. Because of that certification, it will not be legal for use in Little League Baseball for 2018. For 2018, the USABat certification will be required for Little League use. I might recommend reaching out to Easton (888-259-1297) with your Return Authorization number and seeing if they can rectify the situation on your replacement bat.

My son plays travel ball, 9u, starting in August. What bat would be a better fit, the YB17MK11 or YB17MK12?

For a younger player in 9U the 2017 Easton MAKO BEAST Youth Baseball Bat: YB17MK12 would potentially be a better fit than the YB17MK11 as it is an ounce lighter. If a player can swing a heavier bat then that is always best as it will give the player more weight to throw into the baseball.

Can this bat be used next year?

No, the 2017 Easton MAKO BEAST Youth Baseball Bat (YB17MK12) will not be approved for play in Little League for 2018. Little League will begin to follow the USA Baseball Standard for 2018. They will require all bats to feature the USA Baseball Stamp. Unfortunately, there isn't any models currently on the market that feature the new USA Baseball Stamp. Those models will be released in early September.

Can you buy a youth bat now that will be legal through the 2018 season?

You cannot buy a youth bat now that will be legal next year, for the 2018 season. Those new bats with the correct USA stamp will not come out until September.

Is there really a big difference in swing weight between the 28''/16 oz. and the 28''/17 oz. Or are both pretty much the same?

There will be a one ounce difference when comparing the weight of a 2017 Easton MAKO BEAST Youth Baseball Bat (YB17MK12) and a YB17MK11 that have the same length. It is hard to say whether the feel to the player will be much different or the same as each player has a different experience with a bat. I wish I could say one way or the other, but the determination would be up to each specific player.

(1) What did Easton do to lose an ounce on the -12 Mako Beast versus the -11 Mako Beast? (2) Does that difference lessen the performance and/or durability of the -12 version?

(1) Unfortunately, I am not certain of the exact technology change that allowed the 2017 Easton MAKO BEAST Youth Baseball Bat (YB17MK12) to have a -12 length-to-weight ratio. (2) The -12 length-to-weight ratio on this YB17MK12 does not inherently lower the durability or performance on this bat.

What is the difference between the 2017 Mako Beast and the 2016 Easton S2?

The 2017 Easton MAKO BEAST Youth Baseball Bat: YB17MK12 is a two-piece composite. The 2016 Easton S2 is a hybrid bat, so it has an alloy barrel and composite handle.

Can you tell me the exact length of the bat?

The only size we have in stock at this point in time (3/21/2017) is the 28" 2017 Easton MAKO BEAST Youth Baseball Bat (YB17MK12).

Is this bat approved for USA Baseball Leagues starting in 2018?

Unfortunately, the 2017 Easton MAKO BEAST Youth Baseball Bat: YB17MK12 is not legal for play in USA Baseball for 2018. Because it features the USSSA 1.15 BPF certification it will not be legal.

My 10 year old son is about 4'2"-4'4", 55-60 lbs. He currently has a 2016 Easton S500 27/14 that he used all of last year. But this year it is giving him really bad stingers on missed hits during batting practice. I'm contemplating going to composite to help limit the vibration. The smallest composite bat is 28/16 so I am concerned about going up 2 ounces in weight and him ending up late on everything.

Based on your sons height and weight we would recommend a 28"/16 ounce 2017 Easton MAKO BEAST Youth Baseball Bat (YB17MK12). Considering his height and weight I do not think he would have any trouble moving up the additional 2 ounces.

I just bought this bat for my son in a 28 inch 16 ounce -12. I also have last years Mako in the same size 28 inch 16 ounce -12. I am holding them side by side and I don't see any way that this year's Mako Beast model has a longer barrel than last years model. If anything the barrel on last year's model stays wider a little bit longer before it starts to taper down to the handle. The distance from the end of each bat to the point where they start to taper appears to be about a quarter inch longer on last year's model. Can you please try to explain again where I should see this extra 1.5 inches of barrel compared to last year's model?

From what we've determined, the 1.5" barrel extension is only on the 2017 Easton MAKO BEAST BBCOR Baseball Bat: BB17MK model, and not on their other sizes, unfortunately.

Is there a break-in period?

Like with any composite barreled bat, the 2017 Easton MAKO BEAST Youth Baseball Bat: YB17MK12 will benefit from a short break-in period of roughly 150 swings from soft toss. Start off at 50% power and rotate the barrel 1/4" after every 10-15 swings.
