2020 Combat B2 ATB Review

By Bat Digest | Last Updated November 17, 2022

The 2020 Combat B2 is a JustBats production—who acquired enough of the intellectual property rights during Combat’s bankruptcy in 2018 to somehow produce a bat with the name Combat. The B2 is taken from a 2014/15 Combat bat but is put on a reprtin of the Combat Maxum from 2018. That entails the 2020 Combat B2 you see here. We think the Combat Maxum from 2018 was a good to great bat.

2020 B2 ATB Models

Our hitters like the single-piece feel of the 2020 Combat B2. It’s a light swing in BBCOR and USSSA. The drop 5 is a fan favorite as the heavier swing weight and massive barrel make for a fun hit.

The drop 8 for the B2 Ultra is a big barreled bat with a huge barrel and a great swing. Although we don't know much yet, we expect the bat to be a lot like the B2s from days gone by in the Combat space. JustBats, some years ago, picked up some rights to the Combat name when Combat went out of business (via bankruptcy). Easton, a sister company, took over much of the Combat umbrella. But JustBats picked up enough to secure some naming rights in the future. As well, and we don't know, Easton's acquisition by Rawlings may have left some Combat items on the table too. We'll keep asking around.

Those who want a big barrel and light swing and light swing in a drop 11 single piece USSSA are in the right place.

Previous Models

The Combat B2 is a JustBats sponsored and produced bat under the intellectual property rights they acquired during Combat parent company’s bankruptcy. We aren’t sure how it all works, but in any event, JustBats has retained the rights to both produce and sell a bat with the Combat name exclusively.

The Combat B2 takes the name from a 2014/15 Combat line and puts it on the Combat Maxum from 2018—which this 2020 B2 ATB is an exact replica of.

Overall Ratings

The overall rating uses seven different weighted metrics to determine our overall score. Half of total rating comes from the player and our exit speed tests (Player Rating: 25%, Performance: 25%).The other categories are Relevance (20%), Demand (10%), Durability (10%), Resell Score (5%), and Tech Specs (5%).

*: When a bat is denoted by a star (*) it is a preliminary rating. Expect it to be updated as we learn more about the bat and gather more data.

(PlaRa) Player Rating: We measure player rating from user reviews. Those users include our own hitters that we test at the lab as well as reviews we find online.

(ExVe) Performance: Performance measures the exit speeds and distances we capture in our hitting lab with HitTrax using these bats.

(Relv) Relevance: We measure the number of sizes and the MOI of the bat. Bats with a wider range of options get a better score.

(Dmnd) Demand: Demand is measured by consumer sentiment and the buzz around the bat.

(Drb) Durability: A bat’s durability is measured by user reviews as well as feedback from manufacturers.

(ReSl) Resell Score: Based on the price the bats go for used. Higher prices mean greater user demand which means, generally, a better bat. A resell value closer to its original price means a higher score.

(Tech) Tech Specs: We rate the bat on its technological advancements from previous years and compared to the industry at large. This is our chance to reward companies who are trying to innovate.
MOI or Mass Moment of Inertia is a measurement of bat swing weight. This quantifies how difficult it is to swing a bat. The industry often refers to this as things like End Load or Balanced but those words have been overused to the point of meaninglessness. We measure the actual swing weights of each bat we test using the industry-standard pendulum period, balance point, and scale weight. You can read more about that here.
The price is the original MSRP price of the bat.
The types of bats are single-piece alloy (SPA), two-piece composite (TPC), single-piece composite (SPC), hybrid (Hyb.), and wood (Wood). Hybrid bats are made of composite handles and alloy barrles.
