July 6, 1967 -- Stan Bahnsen had already pitched in the major leagues when he faced the Buffalo Bisons for the Syracuse Chiefs in 1967. In fact, he struck out the side against Boston the previous year.
But he took a step forward on this day. Bahnsen pitched a perfect game for seven innings as the Chiefs blanked the Bisons.
Bahnsen went on to a decent career. He was 17-12 in 1968 and won rookie of the year honors in the American League. The right-handed retired the first 23 batters of a game for the White Sox against Minnesota in 1974. He finished with a career record of 146-149.
