2021 Louisville Slugger Xeno Fastpitch Review

The 2021 Louisville Slugger Xeno is a two-piece composite bat with a good-sized barrel and a mostly balanced swing weight. Its differentiating feature is the stiffness of the connection, while all other two-piece composite bats in the performance fastpitch space have a flexible connection. If you want a stiffer connection between your barrel and handle on your fastpitch bat, then the Xeno is where you should look.

2021 Xeno Models

Models Overview

We like the drop 8 and 9 Xeno as some of our favorite power-hitting bats on the market. Big hitters might appreciate the loaded feel and the stiff connection. Smaller hitters who want a lighter swinging bat but a rigid connection should like the Xeno. But, to be sure, most more minor hitters who want bat speed and a soft swing aren’t in the mood for a stiff bat. Instead, they tend more towards a bat like the Slugger LXT or Easton Ghost with a more flexible connection.

The bat was initially made available only directly on Slugger.com’s site. However, some models were since released to a few select dealers.

General Recommendations

Our recommendation is for the Xeno drop 8 and 9 to be in the bag of most heavy hitters who want a stiff connection or, at least, a different feeling bat than their drop 8 Easton Ghost Advanced or Rawlings Mantra. If you wish to drop 10 or 11, we think you’ll appreciate the bat’s durability and the more endloaded feel.

Reviews By Model

Comparable Bats

We don’t know of fastpitch bats as stiff as the Xeno. So, if that’s what you want, this is the bat for you. If you are in the mood for a two-piece composite bat and don’t care about the stiffness in the connection, then you have many similar options.
