Paul Zwaska knows how to take care of a baseball field. He was the head groundskeeper for the Baltimore Orioles for 15 years. Now, he works with groundskeepers across the world in keeping their fields ready for play. We learned about some of the stresses of the job, and one of the nicest things Cal Ripken Jr ever said to him. For more information on Paul, you can follow him on Twitter and you can check out Beacon Athletics, the company Paul works with, for all of your grounds keeping goods & information.
