I can, I did , last time in 1986 in a league in TX that allowed a couple former MiLB players on a roster. Won the state championship in the Pepsi Games in San Antonio. Last time to warm a guy up was a pitcher from Univ of Michigan, not wearing any mask. He fliped the glove for a curveball, threw a 90mph FB past my head, and I walked away, never played with the idiot again.
