It’s a single piece aluminum built with a decent sized barrel and a good average balance swing weight—not too heavy, not too light but just right. We recommend the 519 Omaha to players that like a single piece, want a stiff bat and prefer a wood like feel to their bat’s feedback for hits and mishits. The breadth of sizing options are unmatched in the industry.
Rawlings 5150 is built with the exact same feel and result in mind when compared to the 519 Omaha. Both are single piece aluminum bats with a middle of the road swing weight and decent sized barrel. Both are used by hitters that prefer the stiff feel of bomb making bat and are willing to pay the price (in sting) on mishits.
See our 2019 Rawlings 5150 Review.
In fact, both bats are named similarly because they are that similar. 5150 Alloy, one of the very first alloy’s to make baseball bats, is the genesis of these bats and the genesis of their names. Although both have manipuated the original 5150 alloy into their own special concoction to increase durability and performance the intent remains the same.
Slugger’s 2019 519 comes in more sizing options when compared to the Rawlings 5150. That is only because the 519 Omaha comes in a more sizes than any bat on the market. The 5150 from Rawlings is their most robustly sized bat.
Functionally, there are no differences between the 518 and 519 Omaha. Both are single piece bats with a good sized barrel, average swing weight and a huge swath of size offerings. They both continue to use the same alloy to make up the structure of the bat.
The 2019 version does have a new grip on its handle. For whatever reason, Lizard Skin grips are found on Easton bats for 2019—Slugger has gone with their own grip.
The 519 USA Bat 519 Omaha’s are not out at the time of this writing (October of 2018). The USSSA and BBCOR are. We expect to see similar sized USA Bat vesions of the Omaha by the holidays. In the meantime, check the USA versions in the 2018 518 Omaha as it will be a very similar bat.

The claim is the end cap changed in the 2019 version. This new lighter end cap, at least a few different marketing tracts we read, mentioned something about this lowering swing weight. This may be the case in non-BBCOR versions of the bat, but the 2019 519 33/30 and the 2018 518 33/30 swing with a near identical swing weight.
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.
