Fired Angels clubhouse attendant Brian Harkins names names as he fights for his reputation after being fired by the Angels. Harkins provided what appears to be a wide array of pitchers with a mixture of pine tars and rosin so they could grip the ball better:

Harkins, known throughout the league as “Bubba,” joined the Angels as a bat boy in 1981 and worked as the visiting clubhouse manager from 1990 until the day of his termination on March 3, 2020. In the 1990s, Percival taught him to place rosin, pine tar and Mota stick — a firmer pine tar — in the bottom of a soda can and melt it with a lighter to create the sticky substance that would be widely distributed to home and away pitchers. Harkins provided this blend “as a courtesy,” the opposition states, adding that it was “not a money-making venture” and that “many people within the Angels organization knew about the Sticky Stuff.”

The opposition also included declarations from 16-year major league players Wally Joyner and Mike Sweeney, who emphasized the commonality and acceptance of the practice and lauded Harkins’ reputation. Declarations were also made by longtime Chicago White Sox clubhouse manager Gabe Morell and former Angels bat boy and clubhouse attendant Vince Willet.

Willet noted that Harkins’ mixture of rosin and pine tar was a constant presence in the Angels’ bullpen bag.

At some point, MLB became concerned with teams trying to develop something more high tech. We will see how this plays out.
