Oates (b. 1946 - d. 2004) played in the majors in 1970 and from 1972 to 1981 for the Orioles, Braves, Phillies, Dodgers and Yankees. He had 410 hits, 14 home runs and a .250 batting average.
Oates managed the Orioles from 1991 to 1994 and the Rangers from 1995 to 2001. His overall record was 797-746 (.517 win %).
Fun fact, one of my son's elementary school gym teachers was the widow of one of Oates's coaches (Greg Biagini).
