A tethered ball-type batting practice apparatus comprised of a nonresilient first tether portion, a swivel, a linearly resilient second tether portion, a ball and a moderately flexible sleeve is disclosed. The hollow, lightweight ball cooperates with the resilient second tether portion to reduce the likelihood of the ball being torn from the tether, while giving a batter the authentic feel of having hit a standard ball. The moderately flexible sleeve prevents the tether from wrapping around the batter's bat. And, the resilient second tether portion permits the swivel to work more efficiently in preventing the tether's twisting.
