Blue is the Washington Nationals color. 

When wearing their alternate blue jerseys the Nationals have been unstoppable this postseason. As a result, they've kept wearing them.

Continuing with the blue theme that they have ridden this October, there was a slight change at Nationals Park ahead of Game 3 of the World Series. Can you catch it?

One can never be too careful when it comes to superstitions. Changing the signs seem easy enough. The seats are already blue and at this point the bluer the stadium the better.

So far this postseason the Nationals are 8-0 when wearing their navy-blue threads. This includes the first two games of the World Series against the Astros.

Although not confirmed, in all likelihood it is expected for the Nationals to wear blue again for Game 3. That is scheduled for Friday, Oct. 25 at 8:07 p.m. ET.
