* Willie Mays' 512th round-tripper breaks tie w/ Mel Ott

The frontpage has an image of Willie Mays with the headline: "WILLIE MAYS A Champion is Born". Page 3 has an image of Mays connecting with his 512th home run and an accompanying article. Nice to have this coverage of the future member of the Baseball Hall of Fame in this notable Sports publication.
