The Nationals and Padres dressed in 1936 uniforms - the Nationals as the Washington Senators and the Padres as the PCL Padres. Padres announcer Dick Enberg continuously remarked on the throwback uniforms, even saying the Padres looked almost liked the Yankees with the pinstripes, and when #7 Chase Headley was up, Enberg said, it almost "looks like Mickey Mantle is up at bat." And he later said these old uniforms reminded him of Camile Pascaul, Harmon Killebrew and Wayne Terwillinger.
For their credit, the players appeared to mostly be wearing them well, with stirrups and no pajama pants anywhere in sight. Robert Marshall would be proud.
