Admittedly, scorekeeping at a baseball game is a bit of a lost art — replaced by digital scoreboards, apps, and apathy — but with the Eephus League Scorebook, you can rediscover this simple pleasure, even if you've never kept score before. Compact and easy to bring with you to the park, this book measures just five by a little over seven inches. The book includes 20 scorecards, each with space for up to 11 innings, pitching statistics, and game totals. With a clean, simple deign, they're also easy to work with, while an included reference card and foldout guide make life easy for novices and seasoned veterans alike.
While it may be a bit late to brush up on your skills in time to make it into the World Cup — you can still use the Adidas MiCoach Smart Soccer Ball to step your game up before your summer league starts. Packed with sensors throughout, this ball connects wirelessly to an iPhone app, constantly measuring data about the way you kick, and helping you improve everything from spin and foot plant, to power and strike point. Tutorials in the app coach you on how to curve the ball around a wall, kick a knuckleball, improve your power, and much more.
Unless you spend a lot of time at the local table tennis club, one of the toughest parts of improving your game is finding someone to play. Enter the Killerspin Throw II Robot.

In other words, not only can it help you improve your game, but it might just be even better competition than your friends.
