Though many on- and off-field baseball drills require a partner or full team, it's also possible to develop your baseball talents with a variety of effective and time-efficient solo exercises. One-person drills require little to no set-up, and can be done any time of day without the hassle of gathering other players for a full practice.
Swinging
Dry swings: Practice in front of a mirror without a bat. Keep your eye on something at pitch level, keep your head as steady as possible, and go through the four steps of a swing. Get in a balanced stance, load your back foot, step forward, and pivot your hips.
Cover the zone: With a bat in your hands, practice swinging at all areas of the strike zone. Cover the inside corner, letter high, knee low, and the outside corner. Concentrate on remaining balanced, and using proper form.
Tee-ball: Practice making contact in all phases of batting while hitting the ball off a tee. Hit to the opposite field, hit for power, hit while choking up on the bat, and even practice bunting down each baseline. Hit balls into a backstop if you don't want to chase after them.
Form
Come up throwing/find the threads: Practice with a glove and ball, but never actually throw the ball. Start by dropping down and taking a mock ground ball into your glove. Come up in the throwing position, and as you take the ball out of your glove, make sure to get a four-seam grip. Do this until your fingers naturally begin to spin the ball until you have the correct grip.
Track the ball: Lie on your back on the ground, either in a room with nothing breakable around you, or in a field with a soft surface. Throw a ball into the air above you, practicing the snap of your wrist and proper release points. Follow the ball with your eyes all the way into your glove without fully extending your arm.
Fielding and Throwing
Wall bounces: Using a tennis ball or rubber ball, throw a ball in random directions against a hard wall in a level area. Field the ball before it bounce back past you each time. This will help you to practice taking the best angle at balls not hit directly at you.
Pickoffs and the stretch: In an open area, practice pitching out of the stretch using multiple looks. Try a side sweep, a shorter leg left, and a straight throw. Also practice multiple pickoff moves, without actually throwing a ball.
Arm angles: Using a glove but no ball, practice fielding balls at all angles. Reach across your body low, middle, and high to catch line drives and fly balls. Switch from an overhand catch to an underhand catch on deceptive balls by flipping your glove as quickly as possible.
Catcher's stop and scoop: In front of a solid wall in a level area, throw a hard ball against the lower portion of the wall, to practice stopping bouncing balls in front of you and to the side of you. Scoop the ball and come up in position to throw.
