When their parents are away, the boys will play!

After arriving in Cancun, Mexico Monday to promote his new baseball movie Moneyball, Brad Pitt made sure his sons Maddox, 9, and Pax, 7, spent some quality time together in the tropical locale.

Wearing black and blue swim trunks, a bodyguard kept a watchful eye over Pitt's sons as they boogie boarded in the Gulf Coast. Making the most of their short trip, the boys playfully splashed one another before boarding a private plane with their father hours later.

Earlier in the day, Pitt joined costar Jonah Hill for a Moneyball photo call. "I like to play ball with my boys," Pitt told USA Today, adding that he wasn't a huge fan of the sport growing up. "I knew very little about baseball apart from taking one in the face in junior high."
