Les Biederman: "The Scoreboard: Clemente Seeks 2000th Hit; Recalls His First In 1955," The Pittsburgh Press (Friday, September 2, 1966), p. 21 — Comment: This brief description signifies a 450-foot shot, as would have been apparent in 1966 to most hard-core MLB fans residing in New York; also notable, especially from Clemente's perspective, was the presence of his two North American baseball heroes and mentors, Monte Irvin and Willie Mays, as the opposing right and center fielders, respectively.https://en.wikiquote.org/wiki/Roberto_Clemente
