ROCKY MARCIANO'S brother has his heart set on a baseball career . .. although the heavy weight champion thinks he should seriously consider the ring. So, in his best big brotherly manner, Rocky was responsible for getting the Brooklyn Dodgers to look over the kid this spring at Vero Beach. A couple of Brooklyn scouts were watching Rocky train re cently when the champ mentioned he had a prospect for them—his brother. In checking through their files, the scouts discovered the Dodgers actually had a card on the youngster: “Louis Marche giano, 19, high school graduate. Aptitude, average. Arm, strong. Fair hitter. Good speed. Com ment: What this boy lacks in ability he makes up in aggres siveness and hustle.” Despite a skimpy background in baseball—he concentrated on play ing fullback in football during his high school days in Brockton— Louis was taken to Vero Beach by the Dodgers and the club's brass paid extra attention to him. FRESCO THOMPSON, who di rects the Dodgers’ minor league operations, says the kid has im mne greatly since the card was itst filed . .. and that “we're go ing to keep an eye on him.” Lou, a carbon copy of Rocky, will continue to play semi-pro ball until he completes prep school. He is attending Thayer Academy in Raintree, Mass. The Rock himself, of course, had a major league trial before turning to the ring. The younger Marchegiano, is a muscular lad with huge hands. He stands 5-8 and weighs 175. Although he prefers baseball to the ring, he likes to box and sometimes spars with Rocky. In fact, the champ was suspended in Maine a few months ago for fighting an exhibition with Lou. Rocky believes his kid brother has a much greater potential in the ring than he has. rr. v7 in MEXICO CITY’S new Olympic Stadium, situated in the large sports development called Univer sity City, has become the center of a heated dispute. It was supposed to seat 110, persons .. but a recent seat-by-seat count revealed there were only 58,839, accord ing to the gentlemen who counted ’em. Claiming they were victims of “malicious slander,” stadium offi cials claim it not only can hold 110,000 people .. but already has held that many. The result of the controversy is that a commission has been formed to officially look into the matter. Neutral observers from other countries say that in their opin ion the stadium will seat closer to the 58,839 count. Those from Southern California say it seems smaller than the Los Angeles Coliseum. The stadium plus the other fa cilities in University City was Mexico's “ace-in-the-hole” for a spirited bid for the Olympic Games. GOLE’S BUSIEST MAN these days is Architect Robert J. Jones, who is currently supervising the building of 40 courses throughout the United States as well as one in the Bahamas and another in Nicaragua. He is so busy he has had to turn down a request to lay out a course in Osaka, Japan. Among the courses his crew is remodeling is the Birmingham Country Club layout, site of the PGA championship in July. Most difficult course in the world in Jones’ estimation is the Peach Tree layout in Atlanta, Ga. “No one has broken oat there from the back tees in the five years since we built at,” he says. “The course has only 27 traps, but it is over 7300 yards in length.” In this instance, the length of the course is the main reason for the hard test of golf... but Jones insists that a hole for a c urse doesn’t have to be long to be difficult. Hardest hole to play he has ever seen measures only 100 yards. It is part of a private course he built for Doris Duke at Somer ville, N. J. The green is an island in a lake. After shooting from the tee on shore, you row out in a boat to putt—if you've made the green, that is. “The psycho logical handicap of all that water around the green is tremendous,” Jones points out. “Pars are a rarity.”
