Every classroom had one: a kid huddled at his desk with a transistor radio surreptitiously plugged into his ear, trying to tune in to an afternoon game. Transistors—and, for that matter, daytime baseball—may be things of the past, but with the Sports Trax handheld pager, school- or work-bound fans can still keep tabs on what's happening at the ballpark. Marketed by Motorola and USA Page, the beeper spits out batter-by-batter updates of every major league game, with a delay of about a minute. Given the typical game's glacial pace, that means the beeper display showing the score, inning, number of outs and base runners is almost as current as the stadium scoreboard. Inattentive fans can even program the unit, which sells for $79.95, to alert them when something important is happening; if asked, Sports Trax will chirp when a run scores or play "Charge!" when a rally starts. It also lets a user scroll through the day's finals as well as tomorrow's slate of games. Best of all, it's so small that it's easy to hide if a teacher strolls by.
