Rule 8.02(a) Comment: If at any time the ball hits the rosin bag it is in play. In the case of rain or wet field, the umpire may instruct the pitcher to carry the rosin bag in his hip pocket. A pitcher may use the rosin bag for the purpose of applying rosin to his bare hand or hands. Neither the pitcher nor any other player shall dust the ball with the rosin bag; neither shall the pitcher nor any other player be permitted to apply rosin from the bag to his glove or dust any part of his uniform with the rosin bag.
so, he can put it on his hands, but it cant get on the ball :confused:
