A hitter training device is described that is easily transportable, is not bulky, and does not require complex assembly and disassembly. The hitter training device also readily facilitates hitter training for right-handed hitters, for left-handed hitters, or for switch hitters. The device includes a support, a cord, a ball, and a clamp. The support has a first end, a second end, and a mid-section, and the first and second ends are axially offset from the mid-section. The cord is coupled to the support between opposing portions of the support that are axially offset from the mid-section, and has a length such that, when it is coupled to the support, the cord is not taut. The ball is mounted on the cord. The clamp is coupled to the support and is configured to temporarily mount the support, in a releasable manner, to a structure.
