Bill Sluka was briefly an outfielder in the Red chain in 1967 playing in the Northern and Appalachian leagues. This is Bill Sluka as a right fielder for the University of Denver Pioneers in a photo dated 1964, I have included the back of the photo which gives his position and batting average for that year. Sluka was drafted in the 71st Rd of the '67 draft.
Their is also a John Sluka in the BR , a Michigan native two years younger than Bill Sluka. Some of Bill Sluka's autobiographical information is missing so I have not yet been able to confirm if they are brothers.
