Watch the Nats' Chris Heisey and his 3-year-old son team up for an adorable batting practice

Sure, watching a baseball game is fun. But is it adorable? Is it the cutest thing you've ever seen?
Well, on Thursday, after the Nationals finished in a 2-2 tie with the Marlins, Nats outfielder Chris Heisey came out with his toddler son to put in some postgame BP. Hundreds of fans stuck around to watch the two create a one-of-a-kind father-son moment:

MLB.com's Jamal Collier caught up with Heisey to see how often he throws to him.<o:p>
"Every day in the summer time, every day it's warm enough to get outside. Last night we spent an hour in the driveway just hitting. As much as possible. He's a big boy for his age, but he would do that after games last year in D.C. when fans would be cheering for him."
<o:p>He's also a natural with the fans. 
"He eats it up. He heard the cheers and then he looked up and saw everybody looking at him and then he started showing off. He hit the first ball and they all erupted, so he ran around the bases with the biggest smile on his face."
What a day for the kids of Spring Training.
