Granderson has spent significant time in recent days working with hitting coach Dave Hudgens on his plate approach, focusing on swinging only at the balls he can handle.
"I've definitely had some [slumps] over the course of my career," Granderson said. "I don't remember exactly what was the turning point or what caused the turning point, but eventually it did come. That's the one thing I do remember. So I'm continuing to stay positive with all those different things and realizing it is a part of the game."
