Those seven pitchers accomplished that feat eight times, with one of the hurlers accomplishing it twice – in the same season. Half of the eight times occurred during the 1970’s.
The first pitcher to homer twice in the same game for the club was Jack Knight, who did it on June 24th, 1926 at the Polo Grounds against the New York Giants in a 12-7 defeat. Unusual about Knight’s effort was that it came as a reliever.
Starting pitcher Claude Willoughby had been rocked for six earned runs over the first inning and a third, and was lifted for Knight.
