In the past 12 months, Mookie Betts has played in the World Series of both baseball and bowling

It's difficult for anyone to be as skilled at anything as Mookie Betts is at both baseball and bowling. With extra-base hits in one and effortless strikes in the other, Betts is taking the sports world by storm.

It's one thing to be like the Royals' Brandon Finnegan in 2014 and appearing in both the College World Series and the Fall Classic in the same year. While incredible for his age, it was still the same game for Finnegan. Mookie is going next-level with multiple sports.

For Mookie, they're all there for the taking.
