The brother of Braves pitcher Chi Chi Olivo
, Diomedes was a forty-three-year-old
major league rookie with Pittsburgh in 1962 - possibly the oldest rookie ever, depending
on when Satchel Paige
was really born. The Dominican reliever baffled hitters that
year, going 5-1 (2.77) with seven saves in 62 games, but was ineffective with St.
Louis the following season.
