The Red Sox's young outfielder - and budding MLB superstar - is competing in the Professional Bowlers Association World Series of Bowling VII in Reno, Nevada.
When Betts was in high school, he thought he might have a future as a pro bowler.
He rolled a 224 in his first game as a professional last Tuesday. (Betts has rolled four perfect games in his life, including one recently as he prepared for the tournament.)
Betts: "I watch bowling pretty much every Sunday."
Betts's mother won her state championship when she was eight years old, and Mookie started bowling when he was four.
