Watch J.J. Watt blast home runs off Roger Clemens

Houston Texans star J.J. Watt held his annual J.J. Watt Charity Classic at the Astros' Minute Maid Park Saturday, and during the home run derby Watt hit a few colossal shots off a seven-time Cy Young winner. Former Red Sox, Yankees and Astros great Roger Clemens tossed a few pitches for Watt, who has a pretty impressive swing.

Watt tweeted that the event raised more than $1.6 million for his foundation, which provides funding for youth athletic programs across the country. Even former First Lady Barbara Bush was in attendance to throw out the first pitch.
