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).
