The Senators stake rookie Carl Mathias to a 3 – 0 lead over New York, but a Mickey Mantle solo shot, a few feet left of the 456-foot sign in left at Yankee Stadium, puts New York on the board. The Nats up the score to 5 – 1, but Mantle then bangs a 3-run homer to make it 5 – 4 and knock out Mathias, who in his 11 major league games will give up three homers to Mantle. In the 9th, Roger Maris poles a two-run homer, his 28th, to give New York a 7 – 6 victory.
