9. Ken Singleton – 182 home runs
Ken Singleton started his career with the New York Mets until he was traded to the Montreal Expos for Rusty Staub in 1972. He played for the Expos for three years until he was sent to the Baltimore Orioles in a trade that saw Singleton and Mike Torrez go to Baltimore for Dave McNally, Rich Coggins, and Bill Kirkpatrick.
Singleton played for the Baltimore Orioles for nine years, earning himself three All-Star appearances, and winning a World Series with the team in 1983.
Singleton was an on-base machine, with a career 14.8% walk rate and .388 OBP. His best season came in 1979 when he slashed .295/.405/.533 with 35 home runs, 93 runs, and 111 RBIs, though believe it or not, that wasn’t his best OBP year. That came in 1977 when he had an OBP of .438.
Also, fun fact, Singleton is the cousin of former NBA player and current Los Angeles Clippers coach Doc Rivers.
