"What's this we hear about the Cubs, who detected a batting weakness of Willie Mays, also learning how to pitch to Roberto Clemente, the sensational outfielder of the Pirates? ... It is said that and Sam Jones, who played winter ball in Puerto Rico, not only got hep to Say Hey Willie, but it is more than a coincidence that Clemente has batted only .158 against the Cubs; in fact, he made only two hits in his last five games against them."
