Here's footage from the 2017 PBA World Series of Bowling in which he completes a 300 game easily and just a simple little fist pump to celebrate.
Betts revealed afterwards he has bowled around 10 flawless games in his lifetime, but that this was his first in a Professional Bowlers Association tour event.
The 25-year-old star made his PBA World Series debut in 2015, when he averaged a 190 score. I don't know how much Betts bowls during the baseball season but I have to imagine it's not as much as the bowling pros. This wasn't the first time that Betts has competed in a Professional Bowlers Association (PBA) event, but it was the first time that he rolled a flawless game in a PBA event.
Sunday's round of 10 games proved to be for most of the players, the lowest scoring for the tournament.
Betts ranks 158th in the competition with an average score of 205.60 in 40 games. Betts took part in the even in 2016 and partnered with Jones where the two finished second.
