When the sci-fi fraternity starts mixing futuristic technology and the sports world, the prophecies are almost uniformly grim. The lead-off story here, George R. R. Martin's ""Last Superbowl Game"" which predicts the replacement of live sports by computer simulations, just about says it all. Several stories about robot competitors are presented by the editors as Jackie Robinson analogies; none is quite that, though Gault's android boxer in ""Title Fight"" is surprisingly effective. Predictably baseball brings out flakiness, zero-gravity basketball inspires lyricism, and football occasions predictions of a new age of gladiatorial combat. Yet minor sports account for the most appealing entries here: an old golf pro plays his last round with the devil in Robert Fish's witty slick ""To Hell With the Odds""; Poul Anderson's ""Immortal Game"" is a chess tour de force; Zelazny's masterful ""The Doors of His Face, the Lamps of His Mouth"" is the class entry. A line-up with its share of second stringers, but enough heft to put the odds in its favor.
