The 2023 DeMarini Whisper is a two-piece composite fastpitch bat built with double-walled and huge barrel, light swing and top-end performance. It is DeMarini’s new flagship fastpitch bat and, we believe, attempts to replace the CF in the coming years and really attempts to take market share from Easton’s Ghost.
If you like a light swing and a big barrel, then the 2023 DeMarini Whisper could be your right bat. It’s the biggest drawback of how expensive it is. At $450, it’s one of the most costly fastpitch bats on the market. In any case, it’s built for the player who spares no expense in getting what DeMarini claims is the best they can offer.
The Whisper comes in a drop 10, 9, and 8. The drop 10 comes in a 31 through 34, the drop 9 in a 32 through 34, and a drop 8 in the 33 and 34-inch. Our favorite and most applicable bat is the drop 10, although we think the drop 9 could work well for many hitters.
Consider, too, the double wall construction. Like the Easton Ghost, the Whisper uses two barrels. The outer barrel has a lot of trampolines, and the inner barrel governs the performance to meet the standards. As such, smaller-statured hitters that don’t swing too hard, and don’t compress the barrel as much, can still get great pop.

Comparable bats are two-piece composite with a big barrel, light swing, and great feel on all hits. That includes about every serious fastpitch bat we can think of. DeMarini’s Prism+, DeMarini’s CF, Easton’s Ghost, Marucci’s Echo Connect, and Slugger’s LXT.
There are no previous versions of the Whisper. 2023 is its first iteration.
The 2023 DeMarini Whisper is a new double-barreled bat (like the Ghost) with a loud sound. The connection piece, called the Anomaly Connection, is a bit stiffer and one you’ll find on a bat like the ZOA in baseball. It is a bit stiffer than a bat like the Prism.
It’s most unique feature is the dual wall construction. The idea is the outside barrel has a lot of trampoline for the smaller player. But, when you hit the ball harder and compress the barrel, the inner barrel keeps it from exceeding the standard.
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
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.
Price
The price is the original MSRP price of the bat.
Type
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.
Date
The estimated date the bat began distribution.
