Washington Nationals opening day 2014

(WJLA) - It's here at last! The Washington Nationals are back in D.C. for today's home opener against the Atlanta Braves.

Despite Friday’s overcast skies and chilly early afternoon temperatures, all of the color and excitement of Opening Day was on display at Nats Park.

For many families, Opening Day is a tradition, passed down from generation to generation. For the Knapp family, the tradition goes back to the Old Griffith Stadium in the 1930’s:

"My granddad used to take tickets at the gate. I would stand at the bottom of the ramp, he would wave me up, I would climb under the gate and watch all the ball games," said Ed Knapp.

Little Max Mohaber is here for his very first Opening Day, or depending on how you look at it, his second – his mother was nine months pregnant at Opening Day last year:

"We had to leave the game early to go to the hospital -- so he's a baseball baby," said his mother, Shellie.

Undefeated with a three-game winning streak, there is a lot of hope for big things to come this season.

Despite being slated to pitch in today's game, Tanner Roark started on the mound yesterday. Jordan Zimmermann was pulled because he was apparently sick with flu-like symptoms.If he's better today, he'll start against Atlanta.

But if not, manager Matt Williams had looked at tapping Taylor Jordan for the spot.

The first pitch is at 1:05 p.m.
