Yes, I saw him a number of times at old Forbes Field in Pittsburgh, in the late 50s/early 60s towards the end of his career. I understood I was watching a legend.
His batting stance was different, but a lot of guys then had different kind of stances. One thing my dad always pointed out to me was that he would go to the plate and while he was digging in, he would wipe out the back line of the batters box. When he finally took his stance, his back foot (for him left foot) was mostly outside where the line would have been. That gave him just that extra split second to watch the pitch.
Remember Wes Covington, he would drop his back so far behind his back he looked like he was chopping wood, hehe, maybe he was.
