Dom DiMaggio passed away at 92. Everyone knew Joe D but everyone who knew the game understood that Dominic was every bit the defensive CF as Joe, who to this day is considered one of the best of all time with the leather.
Never knew much about the brothers, Vince or Dom. From reading the bio on ESPN, Dom was a great player and a great man in his own right. And unlike Joe didn't live that solitary life of seclusion, he was a businessman and a family man. In the game of life it seems like he was the more successful.
Rest in peace, Dom. Here's a good obit on Dom DiMaggio. The book mentioned in it, "The Teammates", is a very good read.
