I thought the Marucci Posey smoke bat said it was USA approved on the email I just received today. But all of them I’ve looked at say USSSA approved. Do they have one that is USA approved?
Brandon Todd
Marucci does not make a USA model with regards to the Marucci Posey28 Pro Metal -10 Junior Big Barrel Baseball Bat: MJBBP28S. Currently, the only two USA marked bats from Marucci are the Marucci CAT -10 USA Baseball Bat: MSBC10USA and the Marucci CAT -11 USA Tee Ball Bat: MTBC8USA.
Cameron
Will this bat be good for player pitch?
Scott
No, we do not recommend using the Marucci Posey28 Pro Metal -10 Junior Big Barrel Baseball Bat: MJBBP28S for player pitch. It is a junior big barrel bat and should only be used for tee ball or coach pitch. It can become easily defective if used in player pitch.
Tori
Can you tell me the difference between this bat and the CAT 8?
Michael Thompson
The Marucci Posey28 Pro Metal (MJBBP28S) is made of the same materials as the Marucci Cat 7, except it does not have the AV2 knob. The Marucci Cat 8 uses Marucci's newest AZ105 alloy and their latest barrel technology.
Kyle
Is there a Posey CAT 8 drop 10 in a 32?
Zach
The Marucci Posey and CAT 8 models are two different series of bats. This Marucci Posey28 Pro Metal -10 Junior Big Barrel Baseball Bat: MJBBP28S is designed for coach pitch leagues where the players are 6-8 years of age with the velocity not exceeding 40 MPH. The Marucci Posey28 Pro Metal -10 USSSA Baseball Bat: MSBP2810S is designed for kid pitch leagues up to 12 years of age but 31/21 is the biggest size offered. Same can be said of the CAT 8 series in a drop 10; 31/21 is the largest size offered/made.
Cameron
Is this bat the same as the Cat 8? Both say they have the alloy AZ107.
Lyn Stone
The Marucci Posey28 Pro Metal -10 Junior Big Barrel Baseball Bat: MJBBP28S will be very similar to the CAT 8. The Posey28 will have a slightly more balanced feel whereas the CAT can be used for a little bit more power.
Tori
Is this bat size for coach pitch only?
Jeremy massey
Yes the Marucci Posey28 Pro Metal -10 Junior Big Barrel Baseball Bat: MJBBP28S will only be for coach and machine pitch. Junior Big Barrel bats can only handle slow speed pitches, not durable enough to handle kids pitch.
Ryan
What is the difference between this junior big barrel bat and the regular Posey model? Are they made of the same type of alloy? Just trying to decide which one to by for a 7 year old.
Adam
Junior Big Barrel bats are designed for coaches/machine pitch, it will not with stand kids pitch or pitches typically about 40-50mph.
Ryan
Do you know of any Junior Big Barrel bats that have a USA stamp certification?
Sheldon
At this time, there are not any Junior Big Barrel bats that are USA stamped. Bats like the Marucci Posey28 Pro Metal -10 Junior Big Barrel Baseball Bat: MJBBP28S will only be USSSA approved.
