Mookie Betts rolled a 300 Sunday night in the final qualifying round of the World Series of Bowling in Reno, Nevada.
The Boston Red Sox outfielder guessed that it was the 10th perfect game he's bowled.
"This is definitely the most important one," Betts told the PBA.
Betts is competing in the World Series of Bowling for the second time in three years. Entering Sunday night, he was averaging a 204.71 score through 35 games and ranked 156th out of 195 players.
