What they’re saying

“It's just the angles, the throws. I think once I get more reps over there, I'll be comfortable again. [Dickerson's] big thing is just catching the ball. Catch the ball and throw the ball to first base. Make boring easy. For the most part, they just want me to go out there and play and leave me alone and not put too much stuff in my head.”

“He can catch a ground ball anywhere. The same with Stott. They can play anywhere. A ground ball is a ground ball is a ground ball. Once you understand how they're acting and what ground balls do, once you solve those riddles … the only thing that's different is job responsibilities and your throws.”
