OPTION GUIDE: Should I order this bat stock/untouched or Professionally Broken In?
Brand new baseball and softball bats need to be broken in before they perform to their full potential. Our ProMAX Break-In Service adds 20-40ft of extra distance to your solid hits, improves the durability and longevity of the bat and increases the consistency of your results on solid hits, as well. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a professionally broken in bat in any game or event where it is against the rules.
