I just checked out his profile on CBSSports.com and at first glance I thought it was a picture of Andre the Giant. Of course, the picture may be old--Bartolo could be even larger by now.
Speaking of Eric Gregg, I heard a story about him, maybe someone else has heard it. He was third base umpire for a game and during pregame warmups someone (a player I think) put a cheeseburger on third base while Gregg was looking elsewhere. As the story goes, when Gregg got near the base and saw the burger he good-naturedly took a bite out of it, then gave it to a bat boy or an usher to dispose of. I've always wondered if it really happened.
