Roberto Clemente adds an encore to the previous night’s 3-home run, 7-RBI performance. Les Biederman writes in The Sporting News: “The night Clemente put on his show, only 5,222 fans showed up in Cincinnati. The next night, the attendance jumped to 13,389 and Clemente put on a display during batting practice. He lofted five of six balls out of the park in all directions and when he left the batting cage, the fans applauded. ‘It’s the first time I’ve seen that since Ted Williams’ days with the Red Sox,’ coach Johnny Pesky remarked. Clemente left Cincinnati, trailed by admiring remarks from the Reds.”
