Marucci CAT9 Connect Baseball Bats

Competitive players who want a more end-loaded feel for maximum power—without sacrificing swing speed.

Perfect bat for: 

The CAT9 Connect is going to be in the same market as the Select Power, The Goods, and the Voodoo. It's a two-piece hybrid alloy barrel with a composite handle. It's a top-three bat for me. Very good performer and very popular. Just a great overall product.

Tony from BatExperts

The Marucci CAT 9 Connect is an evolution within the Marucci CAT series, specifically designed to cater to hitters who prefer a slightly end-loaded feel and the additional power that comes with a two-piece bat construction. This model integrates Marucci’s latest technology and combines a responsive, multi-stage-treated AZR alloy barrel with a carbon composite handle for a massive sweet spot. This stiffer connection minimizes vibration and maximizes power on contact. The CAT9 Connect boasts an end-loaded swing weight, ideal for generating bat speed and crushing pitches.

Here is a list that details the progression of this series, highlighting the main features and advancements with each new model.

Progression of the Marucci CAT 9 Connect Baseball Bat

The Marucci CAT9 Connect prioritizes power with a large sweet spot and end-loaded swing weight for strong hitters. The DeMarini Voodoo offers a balanced swing weight and a composite construction for a smoother feel. The Louisville Slugger Select PWR boasts a massive sweet spot with a stiff handle technology for power and control, but the swing weight might be slightly less balanced. Consider your hitting style: pure power with a heavier swing weight (Marucci), a balanced approach with a comfortable swing (DeMarini), or a large sweet spot with some trade-off in swing weight (Louisville Slugger).

**PROS**



* My son enjoyed using. It did not cause any pain and had decent hitting power.
* This bat is a great buy with a lot of pop and no stinging. It has a fast swing and is well-balanced, improving confidence. Kids will love it for little league. 
* Well balanced, no shock, decent pop. My 9 year old likes the added two inches compared to his previous bat. Likes that it doesn’t rattle his hands. Very pleased for the price 

**CONS**



* I purchased this bat for my 9-year-old son to use in little league. Sadly, it did not last long and got cracked in the same weak spot as many other bats.
* The bat snapped in 1/2 while my 9 year old son was hitting.
* My 8 year old son hit very well with it until is snapped in half.
