MLB teams have some fun with rookie dress-up

There's one week left in baseball's regular season, which means the annual ritual of rookie dress-up is upon us.

Costumes were all the rage on Sunday, as teams headed to the destination of their next series.

The Tampa Bay Rays' rookies dressed up as the club's DJ Kitty mascot. The Atlanta Braves' youngsters were Mario Kart characters. And the first-year Minnesota Twins players had a whole mishmash of looks going on.

While all of the aforementioned efforts are admirable, it's hard for any of those teams to beat the Washington Nationals. The Nats, rookies included, donned "Game of Thrones" costumes for their final road trip of the regular season -- and it was pretty darn incredible.
