diamondfans.com notes: Foster was an outstanding outfielder for the Reds throughout the 70s, and a key component of the "Big Red Machine", one of the best teams of the postwar era. He led the NL in home runs twice and in RBI three times. He had his career year in 1977, setting personal bests in most major offensive categories. In his final year (1986) he was baseball's highest paid player. In his prime he was primarily a left fielder, though he played some at all three outfield positions during his career.

He was inducted into the Cincinnati Reds Hall of Fame on August 3, 2003.
