A batting practice device is disclosed which is a tubular elastomeric cylinder closed at both ends and having a mounting tube down the center with a bore capable of receiving a rope or other tension suspension member. A valve is provided for filling the interior portion of the closed end cylinder to a depth of 30% to 70% of the volume with a fluid such as water. The method contemplates providing a batter with such a structure, and repetitively swinging a bat against the subject device to simulate the resistance rebound effect of striking a ball.
