Just so everyone knows a little history behind rubbing mud on baseballs, I'm going to take us back in time. In 1938, umpires began complaining that balls were too white, too slick, and open to tampering. A man named Lena Blackburn, an old Philadelphia Athletics coach, found a spot in the Delaware River, where he discovered the miracle mud. It didn't blacken the ball, but it added grip and kept pitchers from being able to doctor it as easily. The spot on that river in New Jersey is still a secret to this day. The secret was passed down after Blackburn's passing, but the MLB still uses the very same mud for every single game ball.
As for Randy, he has his own secret recipe. He has a few jars of Blackburn's rubbing mud in his office, but they are pricey, and he feels his recipe does the job just as well. Check out the video below as Randy walks us through the making of his own rubbing mud.
After Randy walked me through the steps he uses to make his own rubbing mud, he showed me a finished product. It's visibly darker, but not by much. It's also far less slick. The pitchers are singing his praises. I want to thank Randy for letting us in on one of the biggest secret societies baseball has in it's amazing history.
