With only a quarter of the season gone by, Juan Marichal of San Francisco had nine victories and no defeats, 60 strikeouts and only eight walks, four shutouts, an ERA of 0.59 and a great chance to become the first 30-game winner since Dizzy Dean did it 32 years ago. In his first 10 starts Marichal had eight complete games. In one of the two incomplete games, the Giants led 13-2 after five innings and Marichal was removed to rest up for his next assignment. In the other, an extra-inning duel with the Dodgers, Juan was taken out after 10 innings. Last week he went 14 innings and beat the Phillies 1-0. Marichal not only has the most distinctive pitching motion in the majors—he raises his left leg almost perpendicularly above his head and drops his right hand low, almost to the ground, before rocking forward and firing to the plate—he also has the most distinctive selection of pitches: fast ball, slider, curve, screwball and changeup, plus a disconcerting variety of speeds at which to throw them. For all his success, Marichal has been pitching with a chronic bad back, a pronounced nasal allergy, a bruised knee, a wrenched ankle and a pulled groin muscle. His elbow, which tends to calcify, is packed with ice after each game. Too, there is the pending lawsuit filed by John Roseboro, whom Marichal hit with a bat last year. But Juan has raised his arm against this sea of troubles and, thus far, has more than overcome them.
