A friend passed along this image from a local Washington DC store, selling Washington Nationals 2012 NL East champions t-shirts. The problem? Washington has only clinched a playoff berth, and not the division crown. The Nationals are four games up on the Braves with eight to play, and unlike in the Reds in NL Central and the Giants in NL West, it's possible for Washington to fall out of the division lead before the end of the year and be forced into a wild card spot. Now, that's not an extremely likely scenario given everything it would take for that to happen…but it's still a possibility.
Looks like someone jumped the gun a little bit, and the door is now open for fans to start screaming about a possible jinx involving the Nationals.
