» July 5, 1961: At Yankee Stadium, Roger Maris cracks a 7th inning solo home run against the Indians, and also is credited—erroneously, as it turns out—with a 3rd inning RBI on a single.

With the correction, Maris and Jim Gentile become co-leaders in RBIs for the season.

Chicago's Floyd Robinson makes the game close with a 9th inning grand slam of his own, the 7th Sox slam of the year.
