Dad Catches Home Run Hit by Son

A father made the catch of a lifetime at a minor league baseball game in Davenport, Iowa, this weekend. Conrad Gregor, a minor league hopeful being eyed by the Houston Astros, was playing for the Quad City River Bandits and hit a home run over the fence. A fan in the stands caught the ball but it wasn't just any fan, it was Gregor's dad, Marty Gregor. "You know, it's funny. I probably should have gotten his autograph after the game on the ball. Now, he'll probably charge me for it," Marty Gregor told ABC News.
