He was only the third black umpire in the big leagues, following Emmett Ashford and Art Williams. He officiated in the 1989 World Series, and was the third base umpire for Game 3, which was postponed due to the Loma Prieta earthquake, but since the series ended in four games, he did not get to work behind home plate, as happened to Ashford in the 1970 World Series. He also worked in four National League Championship Series (1981, 1987, 1991, 1997), as well as the 1995 and 1996 National League Division Series and the 1986 All-Star Game at the Houston Astrodome.
