The bat was purchased new and my son used this bat for one Fall Travel Baseball Season and he has outgrown it. Bat is in good condition. Stock language from Marucci: The Marucci Cat 9 Minus 10 Ounce bat for USSSA Travel Ball is a top of the line, one piece, space aged alloy aluminum bat with a ringless barrel. The barrel of the Cat 9 Marruci has a Multi-Variable Wall Design, that gives the bat a larger sweet spot than other bat brand's aluminum bats. This is not an easy way to build a bat, but Marucci is no slouch and doesn't take the easy way out. The one of a kind, second generation Marucci AV2 Anti-Vibration Knob, features a new design to help kill sting and vibration felt in the hands with a harmonically tuned dampening system unlike any other. AZR Alloy is created with a special three stage thermal treatment process. The new AZR alloy gives the hitter a more responsive feel due to a change at the molecular level, giving the Cat 9's alloy more performance and more durability than the previous model. Multi-variable wall construction gives the Cat 9 a larger sweet spot than other aluminum bats, and a thinner more forgiving barrel. 2nd Generation AV2 Knob is a 5 piece system unlike anything else on the market to help stop sting and vibration felt in the hands. This finely tuned design is harmonically tuned to prevent vibration from ever reaching your hands. Ring Free barrel design gives the sweet spot more flex for increased performance and a barrel with no "dead zones". The Marucci Cat 9 with its one-piece alloy design gives a feeling of a clean, consistent, traditional swinging and feeling baseball bat. Barrel and taper are inspired by professional models and input from MLB players on the Marucci Advisory Staff.
