Britton pitched for parts of four seasons in the majors. He broke in with the Atlanta Braves in 1967 and won 11 games for them over the next three years. He missed 1970 with arm trouble, but made the Montreal Expos roster the following year, going 2-3 in 16 games. His best year came for Atlanta in 1969 when he finished 7-5 with a 3.78 ERA and a save. He is notable as the man who surrendered Johnny Bench’s first career home run. According to his Wikipedia page, Britton served in the FBI following his baseball career.
I found it interesting Britton listed Bud Harrelson as the toughest hitter he faced. Harrelson was a career .236 hitter, but I guess he had a lot of success against Britton.
