WASHINGTON — Any kid who’s ever stepped between the white lines dreams of one day playing in a Big League ballpark.

For about 100 young players, that wish came true, albeit without any lucrative contracts, Wednesday.

The 2015 National PLAY Campaign stopped by Nationals Park to promote healthy, active lifestyles.

The lucky young players stretched, ran drills and listened to advice from the pros.

“It’s all about staying active,” says Nationals pitcher Joe Ross. “Have fun, play sports, don’t stay inside watching too many movies, TV shows or playing video games.”

Three members of the Nationals held court with the young ballplayers in the dugout, offering tips on healthy lifestyles and fielding questions like “Where do you keep the chocolate sauce?!”

The Professional Baseball Athletic Trainers Society puts on the traveling campaign, which visits all 30 Major League ballparks.
