Clammy hands can ruin a perfectly good pitch or a great swing of the bat. Keep a rosin bag on your pitching mount to make sure that your pitchers hands stay dry, and blister free, even after a double overtime game! Just grab a handfull of of this stuff, squeeze it into your hand and dust the excess off. Now your ready for the number one fast ball without losing grip of the ball. As far as batters go, even pine tar can wear off mid game so its good to keep a rosin bag in the dugout too. Just keep a little extra rosin in your hand so you can apply it to the bat as well and your good to go.
