Take your focus and hand control to the next level with the one-handed triple catch tennis ball drill. You'll need three balls and the ability to control your fingers and "look the ball into your hand". You can make space for the balls by catching the second ball with just your middle finger or with your middle and ring finger. For an added challenge, ask your partner to throw the balls overhand. If the last ball is tricky, practice catching just that third ball by starting with two balls already in your hand. Remember to practice with both hands and play around with your grip!
