From Sun Deck: By Kaldanials:"Does anyone have details about the J Bench story in Bill Simmons mailbag this week.
It tells of the time Bench kept getting shook off by a pitcher who wanted to throw a fastball, so JB proceeded to catch the next fastball with his bare hand to prove a point.
Simmons ranked it the #1 manliest act in sports."
Seems to me that it was Gerry Arrigo. IIRC, Bench wanted a breaking pitch and Arrigo wanted to throw a fastball. He kept shaking Bench off. Finally, Bench flashed the sign for a fastball. The batter took the pitch and Bench caught it barehanded. Supposedly, Arrigo never again shook off Bench.
