JOHNS CREEK, Ga. -- Cory Willig shares his baseball knowledge five days a week.

The former professional baseball player - and current pro hitting instructor - throws everything into his lessons at D-BAT softball and baseball training facility in Johns Creek, Georgia.

Baseball runs in his veins, and it runs in his family. Cory's son is not even 2 years old and he already swings for the fences.

Getting to a point where we may have to go outside to hit because it's not just baseballs taking damage! 😂 #asherthomas #loveofthegame #fatherson #baseballlife #multipleholidaysgoingonhere #steppinginthebucket



While Cory played baseball, his wife, Leah, and their son, Asher, watched from home.

"He became obsessed with baseball," Leah said. "Then he started going to the batting cages. That's when Cory started shooting all the videos."

Asher's cuts and Cory's camera made the toddler a swinging sensation. His highlights have appeared on ESPN's 'SportsCenter', and the Willigs even traveled to New York for an in-studio appearance on NBC's "The Tonight Show Starring Jimmy Fallon" where Asher beat former MLB star Alex Rodriguez in a hitting competition.

"Seeing all this unfold, it's been exciting," Cory said. "We couldn't be more thankful."

Baseball's youngest prospect can't get enough.

"We wake up getting hit by baseball bats," Cory said.

It's love for the game that sticks around for generations. Less than a year after Cory's father, Robert, lost his battle with cancer, Asher is up to bat.

"He instilled in me the passion for this game - and love - and that's something I wanted to share with Asher. That's what we do. This is our thing," Cory said.

There are no guarantees Asher's talent is anything but a phase.

"If he chooses to continue this, and love the game, then he does," Cory said. "But if not..."

"We're his biggest cheerleaders in whatever he chooses to do," Leah said.

Right now, it's beating A-Rod. And maybe nap time.
