Triangle Drills
Players in groups of three in a triangle. Players take rolls as coach, Short Stop and Second Baseman.
Position players 10 feet apart. Players assume an "athletic position." The "Coach" then underhands the ball to one player, who catches it with their glove. The player takes the ball with throwing hand and flips it to other player. Repeat drill with both players.
Coach starts with easy glove side underhand tosses, then moves toss to center and to throwing hand side. As players progress, move ball into all reachable areas.
