Therefore, old stamp bats will never have to test at a compression rating other than 220. It is important to note the compression testing standards are also grandfathered in with each stamp. The availability of the old stamp bats will naturally diminish as bats break or fail compression. USSSA has announced they will accept both old stamp and new stamp bats in 2021 and moving forward. Moving on to the important stuff, how does this change impact the sanction you play in? Each sanction can, and will, decide which bat stamps are approved for play within their organization.
Testing has proven that there is no loss in performance between the two and many bat reviewers are now seeing that as well, such as the slowpitch bat bros. To clarify this mess of information, the old stamp bats get “hotter” much quicker while the new stamp bats take more time to break-in, but last much longer. Please note manufacturers can still make bats to meet the 220 compression standard but they can no longer have the USSSA Stamp. Beginning with 2021 models, USSSA is using the new 240 compression standard with the new NTS stamp. The old stamp bats were made from 2012 to 2020 and meet the 220 compression testing standard. The bat market now consists of bats that are made with either the old stamp or the new stamp. USSSA announced in early 2020 their intention to move to a new stamp with a higher compression rating.
The stamp on the bat defines the failing compression rating of the bat. The trampoline effect translates to the exit speed of a ball off the bat. Rigid barrels have a lower trampoline effect while flexible barrels have a higher trampoline effect. A bat with a lower compression reading means the barrel walls are more flexible and easier to compress. Historically, a higher compression reading depicts a more rigid barrel with a barrel wall that is inflexible. The compression reading translates to the rigidity or flexibility of the barrel. Bat compression testing defines the amount of pressure required to compress the barrel of a softball bat. In order to address these concerns, we must first gain a clear understanding of bat compression testing and the purpose of the stamps. For example, how do these changes impact the sanction you play in? How do these changes impact the player? How do the old stamp and new stamp bats compare? The intention of this research is to clear up these questions to help the average player make educated decisions regarding their 2021 bat choices. This information seems to come in pieces and does not fully address the questions and concerns of all stakeholders in the softball community. Over the last year, the slowpitch softball world had been inundated with countless announcements regarding changes to the USSSA bat stamp. Written by, Joshua Kusich – Pure Sports Rep
