2020 DeMairni CF Fastpitch Review

March 4, 2021 | by Bat Digest Review Team | @BatDigest

Our 2020 DeMarini CF Fastpitch review consisted of 400 hits, from 3 different players on both live pitching and tee work. Overall, we rated the 2020 CF Fastpitch bat as the best fastpitch bat for 2020. If that isn’t saying enough, we loved the exit speeds, sizing options, swing weight and feel. We think the bat, to say the least, is highly recommendable.


The bigger and stronger the hitter then less then tended towards the 2020 DeMarini CF. Still, they liked it—but was not at the top of their list. Every average to smaller hitter that used the CF fastpitch was blown away. It was in their top 3 of the 11 performance bats we extensively tested… Jump to the full review.

Quick Review

The bigger and stronger the hitter then less then tended towards the 2020 DeMarini CF. Still, they liked it—but was not at the top of their list. Every average to smaller hitter that used the CF fastpitch was blown away. It was in their top 3 of the 11 performance bats we extensively tested. They loved the feel, barrel size and perceived (which we confirmed) pop off the bat.

There are two drawbacks to the 2020 DeMarini CF Fastpitch bat. First, it is expensive. The bat, although priced where other performance fastpitch bats are, is not kind to the wallet. If you’re on a budget that is sub $349 then we suggest you try and find last year’s model, buy a used one or look at the best value fastpitch bats we found. Second, the bat only comes in a drop 10 and 11. Granted, the length options in each of those drops is considerable. But, if you’re a drop 8 or 9 hitter looking for more of an end load then the 2020 CF fastpitch line isn’t going to be you’re oyster.

Otherwise, even drop 12 hitters, will find a reasonable sized and feeling option in the 2020 CF. It swings very light so a drop 11, 29-inch would work well for those 30-inch drop 12 hitters too. And, the real meat of most lineups—the drop 10 32 to 34-inch world—will be, and should be, dominated by the 2020 DeMarini CF Fastpitch.

Fastpitch CF Recommendations
2020 DeMarini CF Review

If you are looking for a light swinging and big barreled fastpitch bat in the drop 10 or 11 space, and buget isn’t much of an issue, then the 2020 CF will be the best bang for your buck, literally. For the average to small hitter, the exit speeds are top shelf, feel is fantastic and barrel size worth noting.

For those who need a bigger swing weight and want to stay in the DeMarini line then the new 2020 DeMarini FNX is where you need to be.

2020 vs 2019 CF

The only real change from 2019’s CF Zen in fastpitch to the 2020 CF is the end cap. DeMarini resigned the end cap to help with durability. That end cap change, according to our swing weight measurements, imperceptibly lowered the swing weight of both the drop 11 and 10 for 2020. They refer to this new end cap as the ReAction End cap which is also found in the new 2020 Baseball DeMarini CFs and Voodoos.

Otherwise, expect the same Paraflex plus composite, 3-fusion connection and grip found in the 2019 DeMarini CF Zen fastpitch bat.


Bat Review

CF Zen

We hit the 2019 CF Zen Fastpitch bat in a drop 10 several hundred times with a few different types of hitters. Exit speed, ball distance and the general feedback from hitters was recorded. As well, we spent considerable time discussing the bat with major vendors and reading any early report online reviews we could find. That data is put together in this 2019 CF Zen Fastpitch Review.      

Price Check



DeMarini's CFX (the new CF Zen) in fastpitch is a light swinging two-piece composite with a big barrel. The bat's connection piece is less stiff compared to other fast-pitch bats like the LXT or Xeno. The differentiation between fastpitch bats is very little, and this bat, in the right hands, can perform as well as any hitter on the planet.

Few bats hold a candle to the CF9 series of DeMarini Fastpitch sticks.

Comparable Bats

The CF is the LIGHTEST swinging drop 10 in the performance fastpitch space. The next closest is Slugger’s RXT. Also, based on our calculations, the 2020 CF swings about 4% lighter than the very popular LXT—which people often associate with light swinging. The light swing weight of the CF is its most differentiating structural feature.

But, in terms of similarities, there are plenty of two piece composite bats on the market with a less stiff connection, big barrel and price point. We think the Slugger LXT is the most honest comparison. Although the LXT comes in more drop sizes. Still, the LXT and CF have mostly similar swing weights, barrel sizes and good responses from players and parents. Without surprise, both are also the most popular fastpitch bats on the market.

2020 RXT
See the RXT Review

Our 2020 Louisville Slugger RXT Review entails three different hitter feedback on over 400 hits both live and off a tee. We measured the bats swing weight and balance points in relation to all other performance fastpitch bats for 2020 and 2019. We took video and recorded some directly player feedback. In short, the RXT is a two piece composite built with a large barrel, stiffer connection than the LXT and a middle of the road swing weight. It replaces the PXT in the 2020 Slugger offering but is more like a stiffer connection in the balanced LXT than it is an upgrade of the heavy swinging PXT.

2020 LXT

In June of 2019, Slugger released the Louisville Slugger LXT 2020. It comes with many of the same great features (even all of them) as the 2019 version. The Louisville Slugger LXT for 2020 review, ratings and places to buy are below.

2020 Prism
See the Prism Review

For 2020, DeMarini has released the Prism out of its D-Labs and into the broader market. They also added a drop 11 to its very popular drop 10 status. For the drop 10, it is the same bat as the 2019 version. For 2019 it had a limited release. No matter what you call it, the Prism is the same double barreled light swing with a massive sweet spot, fantastic feel and a balanced swing. See DeMarini’s D-Labs where the Prism was born. In its original release, due to unexpected demand, the Prism was hard to find in stock. These days its pretty available at just about every major, serious outlet.

2020 DeMairni CF Fastpitch Review

Drop 10 vs Drop 11 2020 CF

There are two measurable differences between the drop 11 and drop 10 CF fastpitch bats for 2020.

  1. The Drop 10 has a shorter and more stockier barrel than the drop 11’s longer and more sleek barrel. That is, if you want the bat with the longest barrel than the drop 11 has about an inch on the drop 10.
  2. The swing weight on the drop 11 is about 2.5% lighter than the drop 10 in similar sizes. That 2.5% is on the verge of being imperceptible. Meaning, most players would not even notice. In any event, the drop 10 and 11 are the lightest swinging performance fastpitch bats on the market for their respective sizing.

2020 CF Construction

Lilke all companies do, there are several marketing jargons used to explain otherwise straight forward peices on the 2020 DeMarini CF. We work through each one and highlight the jargon in bold so you can know what the sales person is talking about.

As they have for a couple years now, DeMarini uses a Paraflex Plus Composite for the barrel. This is, at its core, a plastic composite made proprietary by DeMarini to be big, strong and light. They use this same composite material on the barrels of their popular baseball bats. Other companies have their own spin on the right mix of composite and, for all we konw, they could be very similar. Still, this is DeMarini’s take on the right kind of composite for high end performance bats.

For a few years DeMarini has used a connection piece they refer to as 3-Fusion. It is, in effect, a connection piece utilizing 3 different pieces of composite to keep the handle and barrel together on impact. The idea is to be stiff enough to hit bombs but not so stiff that it hurts your hands on mishits. Most high end performance bats from other companies have their own take on a connective piece. DeMarini’s 3-Fusion, which is used across many of their performance baseball and fastpitch bats, proves a legitimate one for sure.

On their CF line for 2020 they added a new end cap called the ReACTION End Cap. This is a common upgrade when a bat line improvement that responds to any general swing weight or durability issues in previous models. The new end cap adds a bit more lightness (at least as we measured it in our 32/22 and 32/21 2020 fastpitch CF) without sacrificing durability (or so is the claim) from last year’s 2019 CF Zen.

Bat Sizing Options

DeMarini’s 2020 CF in fastpitch comes in both a drop 10 and 11. Sizes range from 30 to 34-inch and 28 to 33-inch respectivley.

  • Drop 10: 30, 31, 32, 33 and 34-inch
  • Drop 11: 28, 29, 30, 31, 32 and 33-inch
