For baseball fans, next Monday is a major holiday – it’s Opening Day. Proclaim your allegiance to your favorite team with an authentic throwback jersey from Distant Replays Retro Sports Store, like a 1917 Chicago White Sox road jersey. ($225). If you’re one of those freaky stats-spouting baseball nerds, you’ll love Turbo Stats baseball software, which allows you to keep score on a Palm PDA and then go back to your PC and crunch those numbers any way you wish ($39.95 to $179.95). Playing catch speeds up with with the Laser Ball, which displays the speed of your pitch upon impact ($11.95, pictured). If you’re confined to your office during day games, keep up on the scores with the SportsCast Wireless Baseball Scoreboard, which updates via satellite every 15 minutes, with no TV, PC or subscription needed ($99; order now to receive a limited edition baseball). For a more retro look, check out the Liveboard ($199), which uses Bluetooth technology to track games. Another desk accoutrement that captures the baseball mystique is the Levitating Baseball – you can even control its spin and speed ($19.99). And here’s your chance to play George Steinbrenner: USAopoly My Major League Baseball Edition is the first customizable Monopoly game in which players buy, sell and trade teams in an effort to control Major League Baseball ($34.99). For the serious fan, there’s nothing like a road trip. Check out the baseball tour packages from Sports Travel and Tours; tours include tickets, hotel, transportation from city to city, and more (and if you can’t find your dream trip, you can customize your own). The gift shop of the National Baseball Hall of Fame in Cooperstown is the ticket for everything from caps and patches to baseball cards and signed baseballs while the Negro Leagues Baseball Museum pays tribute to some of the greats; we like this commemorative leather jacket ($295.95). If you’re into memorabilia, check out MLB’s auction site; you can even “steal home” by bidding on one of these home plates!
