With the Easton MAKO and MAKO Torq getting all the publicity these days, I think the industry might be missing an impressive addition to Easton’s now gigantic Power Brigade line. The Easton S2z is a new concept bat from Easton that incorporates a few industry tricks and the shell of the new Easton S2.
Like the 2015 Easton S2, the S2z has a composite handle with spiraled graphite to help dampen sting as well as the new HyperLite aluminum alloy barrel.
However, and most notably, unlike the S2 the 2015 S2z has an internal carbon sleeve, under the new-fangled aluminum shell, that runs the length of the barrel. This allows enough strength in the material to extend the barrel dramatically (like 3 real inches) yet still give the bat an aluminum feel and sound. It also allows the engineers to create a thin-walled aluminum barrel for ideal swing weight. Easton is referring to this technology as Z-Core internal technology. The Z-core name, if that sounds familiar, is a shout out to the greatest bat ever made.
Currently, the bat is released for only a BBCOR size. This may explain why the 2015 S2 is only in little league versions of the bat. However, Easton has been known to claim the bat is only going to be a certain size only to release other versions of the bat before springtime rolls around.
Overall we are quite excited about this new concept bat. We expect it to be a great fit for those BBCOR hitters who want an aluminum barrel with the barrel and sweet spot size of a composite bat. Those looking for a new concept bat and are willing to try something a bit different this year may very well be looking in the right place.
We recommend the 2015 Easton S2z for hitters who: Prefer aluminum barrels; Like hybrid and two-piece bats; Are looking for the latest innovation from, arguably, the leader in the metal bat space; Prefer a balanced to light swing weight; Also need a BBCOR bat.
We do not recommend the 2015 Easton S2z for hitters who: Prefer composite barrels; want a one-piece bat; are on a budget; little leaguers (as the S2z isn’t available in their size).
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.
