Rosin

Pitchers pick up the rosin bag and tap or squeeze it a few times on the fingers of their throwing hand, then set it back down behind the mound. The fine powder that comes through the cloth absorbs sweat for a drier, more consistent grip. Rosin goes on the hand only, never directly on the ball or the glove. Shop all rosin bags.

It's a matter of feel. The Rawlings Small Rosin Bag (Dry Grip) contains a powdered rosin mixture for pitchers who prefer a dry hand, and comes with a reclosable polybag. The Rawlings Large Rock Rosin Bag (Tacky Grip) gives a slightly stickier feel. The Gamma Rosin Bag holds 1 ounce of rosin powder in a fabric pouch to keep hands dry for better traction.

In most baseball and fastpitch leagues, pitchers may use a rosin bag placed near the mound or pitching circle, applied to the bare hand. Putting rosin or any other substance on the ball, the glove or the uniform is generally not allowed. Rules can vary by association and age group, so check with your league or umpire.

Rosin is a powder that dries the pitcher's hand for a better grip on the ball. Pine tar is a sticky substance that hitters apply to the bat handle for a firmer grip, and pitchers aren't allowed to use it. Hitters looking for more grip can also use bat grip tape and grip products from our bat accessories, along with batting gloves.

Keep your rosin bag dry. Moisture makes the powder clump and stop working well. Store it in a sealed bag, like the reclosable polybag included with the Rawlings Small Rosin Bag, in an outside pocket of your bat bag, away from wet towels and water bottles. Replace it when it no longer releases powder easily.

Along with rosin, wristbands stop sweat from running down to the throwing hand, and a towel in the dugout lets pitchers dry off between innings. On cold days, a handwarmer, like the Nike Pro HyperWarm Handwarmer, keeps fingers warm and responsive. Find both in our wristbands collection, and see all player accessories.
