Bat Benefits

Marucci does not rest on past laurels and they strove to create an even better bat with this CAT 9 Connect. They've introduced three new advancements that will certainly turn heads at the diamond this season. (1) The new AZR alloy endures a 3-step thermal treatment process. The result of that process is an alloy barrel that feels better, is more forgiving & performs better. (2) The Longitudinal Groove System (LGS) is implemented on the fattest part of the barrel and removes excess weight. This results in a little more barrel flex and bumps up performance too. (3) The Outer-Locking System (OLS) attaches the handle and barrel in a unique manner from the "outside in". You'll notice a larger-looking connection piece on the bat. This creates an incredible stiffness and limits nearly all vibration.

All of this new technology is wrapped together in a two-piece, hybrid design that is painted in a sleek, black colorway!


Marucci is a stand-up outfit and they certainly cover this bat with a twelve month manufacturer's warranty period. If you buy this bat from JustBats and notice some goofy in regard to performance or structure, give our Bat Experts a shout. They are on PHONES at 1-866-321-2287, EMAIL at or on CHAT by clicking into the chat box in bottom right corner of this page.

Didn’t last 30 days Wayne Spadafora Parent

Pros: My son loved this bat, vibration minimal, great pop

Cons: This bat broke into two pieces after less than 30 days, didn’t see an actual game. It’s new, so covered under warranty, however this doesn’t look good on it’s durability or overall rating

Questions and Answers (1)

Have a question about the Marucci CAT 9 Connect BBCOR Baseball Bat: MCBCC9? Ask our team of experts and they will respond within 24 hours.

My son is almost 6’, but only around 150 lbs. Could he handle a 33” in the Connect? He is a freshman. He has a CAT 6 and loves it. It’s a 31” (he grew a lot).
Based on the player's height and weight, we would recommend getting the Marucci CAT 9 Connect BBCOR Baseball Bat: MCBCC9 in a 32 inch size. If the player is comfortable moving up to a 33 inch bat there is certainly nothing wrong with that. The Marucci CAT 9 Connect BBCOR Baseball Bat: MCBCC9 will feature more of an end-loaded swing weight though compared to the balanced feel of the CAT 6.

Understanding this professional standard of perfection has allowed us to handcraft a performance product that will last consistently maximize your game.
