If I'm coaching this team, when Desmond leads off, he looks down to Porter in the 3B Coach's box and sees a big ol' take sign, every time until he learns some plate discipline.
I have no problem with a player swinging at the first pitch, but ONLY IF that player has some discipline. Go up there, sit dead red, and look for the fastball in about a 8"x8" area. If it's not right there, or spinning, let it go.
