Polite little baseball fan horrifies his family

A young baseball fan in the United States has horrified his family after politely throwing a prized game ball back onto the field.

Unlike sports in Australia, when a ball rockets into the crowd in baseball, whoever nabs it first is able to keep it.They're valuable prizes that usually end up mantelpieces, but are also regularly sold online, fetching thousands of dollars.The young Seattle fan was sitting with his mum and brother when a ballgirl picked him out of the crowd to hand him a foul ball that had flown off the bat of Mariners star Robinson Cano.In anyone's books, it was a gift worth keeping.But the boy, presumably heeding life's lessons, immediately tossed it back to return the ball to whoever owned it.His family's reaction was as priceless as the ball they'd just lost.But there is a happy ending. After seeing what happened, the ballgirl saved the day, fetching the ball to return it to the youngster who proved he was a quick learner by holding on tight.
