Marty Riessen will never be everyone's top-seeded tennis idol -- it's been more faults than aces, so to speak -- but here in this my-life-on-the-court resume he does occasionally put his racket where his mouth is, and that can't do any harm in a sport which has traditionally suffered from too much politeness and not enough chutzpah. He blasts the charade of amateurism (""shamateurism""), telling how once at ""payoff time"" he collected the money, stuffed the bills into his shoes ""and trod my way daintily through Caracas Airport, feeling like some lucky Western gambler in high-heeled boots making his getaway from Dodge City."" (That sounds like Richard Evans who's always had a weakness for florid metaphors.) There's also a harsh word or two for his old doubles partner, Clark (Kent) Graebner; an infrequent smash aimed at the International Lawn Tennis Federation (Riessen has been with the pro World Championship Tennis group since 1968); a no-alibi account of that headline Davis Cup disaster in Ecuador a few years ago (we took ""a bunch of shovels"" instead of tennis rackets to Guayaquil). And the usual recitals of his own tough match points, etc., plus ""a few tips"" on improving your game tacked on. More than a gentle volley, less than a booming service.
