Rumor has it he even learned he'd been acquired by the Blue Jays while watching Golf Channel. A network on which he made an appearance, where he told the audience he's been playing since age 3 and actually goes to the driving range to work on and add rhythm to his baseball swing, whenever he happens to be in a wooden-bat slump.
