Horace "Hoss" Clarke was one of my favorite Yankee players while I was growing up in the late 60's and early 70's when the Yankees were permanently ensconced in 4th place. As a Little Leaguer, I tried to emulate his very wide open batting stance! I remember the game when he hit 18 or so straight foul balls then homered.
