Who is Marucci?

Cat 9 Baseball Bat

Back in 2004, two former Big League players alongside their trainer crafted the first batch of Marucci Wood Bats. In addition, the Marucci brand started in a humble workshop located in Baton Rouge, a far cry from the current success the brand is experiencing now. Furthermore, the first batch of the Marucci baseball bats embodied the sworn craftsmanship and consistency of the brand that is still evident up until today.

Over the years, Marucci has maintained the high caliber of work they retained throughout the year, giving them a shot into the big leagues. As a result, Marucci became one of the biggest baseball bat manufacturers in the field of baseball, trusted by amateurs and professionals alike. Today, Marucci is one of the big names in the MLB, gracing the hands of professionals such as Francisco Lindor, Anthony Rizzo, and Buster Posey.

Marucci believes that all players deserve excellent gear that can unleash their best during games; therefore, every product that comes from Marucci undergoes a meticulous inspection. Moreover, this inspection by Marucci includes the approval of big-league players through a Player Advisory Board to ensure high-quality gear to the masses.

All in all, if you are looking for premium baseball gear to accompany you throughout your baseball career, you can never go wrong with the Marucci Cat 9 series and its seal of approval from professionals and amateurs alike.

What to Look for When Buying Cat 9 Baseball Bats

Cat 9 Baseball Bat

Now we all know who Marucci is, we can now look at the various things to consider when buying a Cat 9 Baseball Bat. Of course, we don’t want you to end up with the wrong Cat 9 bat that doesn’t fit you and your preferred playstyle when you stand on the plate. Therefore, we have made a buyer’s guide to ensure that the bat on your hand maximizes your performance swing after swing.

Bat Drop

The bat drop of a baseball bat indicates its length in inches subtracted from its weight in ounces. For instance, a 31”-long bat that weighs 28oz will have a bat drop of -3. However, bat drops should vary depending on age and player capability.

As stated, identifying a bat drop for a player is not a one-size-fits-all process; therefore, we recommend various bat drops for different ages and leagues. As a rule of thumb, we recommend a bat drop of -9 to -12 for U12 players. On the other hand, when it comes to high school to professional level play, a bat drop of -3 is a safe choice.

Barrel Size

The barrel size of baseball bats varies depending on their construction. However, we recommend buyers pick a baseball bat with a barrel size between 2 ¼” and 2 5/8” for it to meet the USA Baseball Bat Standard for official use. Luckily, the Cat 9 BBCOR Baseball Bat fits this description, boasting a barrel size of 2 5/8”.

One-piece vs. Two-piece

Baseball players worldwide know the ongoing debate between one-piece vs. two-piece construction bats. As a result, there is a divide between opinions regarding this matter.

Usually, one-piece bats are the choice of players looking for a robust bat that feels stiff, producing a powerful swing for contact and power hitters. Conversely, two-piece bats are for players who prefer a bat that provides enough flexibility to execute a trampoline effect to the ball, enabling a lightweight feel while still providing ample force to the ball.

If you are looking for an excellent two-piece Cat 9 Baseball Bat, we recommend you check out the Marucci Cat 9 CONNECT -3 BBCOR Baseball Bat.
