Tiny Tim works with a three pitch reportoire, a low 90's fastball, a hammer curve and a change-up. Collins sets-up like Jesse Carlson or BJ Ryan with his back to the hitter which helps him hide the ball well. Here is Tim pitching in a spring training game.
Collins is a little vertically challenged, for fun here is a shot of Collins and Trystan Magnuson.
