•JUST SMASHING Fischer’s Magnetic Speed tennis racquet won’t fix your forehand, but hit the sweet spot, and you’ll feel the difference. During normal play, a racquet’s frame deforms slightly on impact before springing back. With the M-Speed, two unipolar magnets positioned in opposite sides of the head help speed the recovery so the ball is catapulted back over the net with extra oomph. Anna-Lena Groenefeld of Germany and other pros compete with it. Tennis anyone?

•SPORT SHADES These amber-tinted MaxSight contact lenses from Nike filter out blue light to reduce glare and improve the visibility of baseballs, tennis balls and other moving targets. A gray-green version gives golfers an edge by enhancing the dips and curves of a distant putting green. Orioles second baseman Brian Roberts credits his MaxSights with boosting his batting average last season; Michelle Wie wore them during her professional debut. The lenses, like those in any decent pair of sunglasses, also filter out ultraviolet rays.
