Mickey(2004)

Best-selling author John Grisham deviates from his usual literary thrillers with this winning film that stars Harry Connick Jr. as Tripp Spence, a widower who goes on the run from the IRS with his 12-year-old baseball-phenomenon son, Derrick (Shawn Salinas). They assume new identities and flee to Las Vegas, where Derrick, now known as Mickey, joins a team that makes it to the Little League World Series. But will fame give away his true identity?
