RUBBING MUD

For the last seventy five years, umpires have used Lena Blackburne rubbing mud to break in brand new baseballs before every major league and minor league game. This New Jersey mud takes the shine off game balls and creates enough friction to give pitchers a firm grip on everything from sliders to knuckleballs.

Now you can buy an 8 oz. container to break in your team's new balls or a single use size to use on your new baseball wallet. For more history and to see a video of how major league umpires prepare game balls, go to Lena Blackburne’s baseball rubbing mud web site.
