HOUSTON -- We used to be impressed that one player's event could sell out a minor league baseball stadium.

Well, as is his custom, J.J. Watt is now trying to reach a seemingly impossible goal.

Next year, for the fourth annual J.J. Watt Charity Classic, he's using Minute Maid Park as a venue. A stadium whose regular residents, the Houston Astros, a resurgent playoff team, had trouble selling out this season.

"I’ve had people say, 'You can’t sell out Minute Maid' and I say, 'You don’t know our fans,'" Watt said. "So I’m looking forward to the opportunity to prove people wrong and to hopefully sell out Minute Maid and put on one heck of a show."

Minute Maid Park has a capacity of more than 40,000. For the past three seasons, Watt held the event at Constellation Field, a minor league park in Sugar Land, Texas, which seats 7,500 people. It has sold out each year within minutes of tickets going on sale.

The event begins with a home run derby between several Texans players, followed by a softball game in which the offense plays against the defense. Next year's event will be May 14. The proceeds go to the J.J. Watt Foundation, which helps fund after-school athletic programs for middle schools, with a focus on Wisconsin and Texas. So far this year they have donated $647,064.44 total to 82 schools, according to the foundation's website.

"When we did it the first year, we literally had no idea what to expect," Watt said. "No idea how much money we were going to raise, no idea if people would show up, if it would be fun. It has just been bigger than our wildest dreams, so it’s incredible. I’m so thankful to our fans, and the players have a great time. They’re unbelievable helping me out with it. We’ve raised so much money and helped so many kids that this year’s going to be something truly special."
