Professional poker player Greg Merson of Laurel Maryland has been showing off his Baltimore Orioles pride out in Las Vegas for the World Series of poker.

Greg Merson rocks an Adam Jones Orioles jersey

Monday, Greg Merson sported an orange Adam Jones jersey, Tuesday pulled out the O’s black one. Perhaps we’ll see the road gray tonight.

I don’t know a thing about professional poker, but this article from the Washington Post says that Merson is guaranteed to win at least $3.8 million. His twitter profile, featuring the picture of McLovin and a Dallas Cowboys background, says he is a 2012 bracelet winner.

That sounds good.
