I found thoughts of ballet crossing my mind occasionally when viewing some old baseball footage on the telly recently. The less inhibited motions of pitchers in days gone by made for some very interesting effects on the mound. I was watching Bob Gibson strike people out, and noted not only the off balance battement produced by his leg kick, but the remarkable follow through where he seems to be heading towards the hitter in a sort of traveling arabesque. The demi-pointe positions taken by Ron Guidry, and Juan Marichal's super high extension also come to mind.
Anyway, those were my reflections, pointless though they may be.
