What they’re saying

“It's going good. I don't throw it nearly as far as Yoshi, but from when I first started to now, it's like night-and-day difference. Even me just throwing the ball across the diamond, it's a lot different than last year in a very positive way.”

— Mookie Betts

“Yoshi, what he did, going back-to-back (days), how he stays healthy and whatnot, why not? If Yoshi can do it, and you see what he's doing, I figured I could be a Yoshi at shortstop.”

— Mookie Betts

“This offseason, I did a little less. Two years in a row getting to the World Series and whatnot, I just really kind of chilled and tried to recover from all the little bumps and bruises and whatnot.”

— Mookie Betts

What’s next

Betts will continue working with Yada Sensei on his javelin throwing and other unorthodox training methods as he prepares for the 2026 season. The Dodgers will monitor his progress at shortstop and hope his renewed focus and unique training regimen will help him win the Gold Glove award this year.

The takeaway

Mookie Betts' willingness to embrace unconventional training techniques under the guidance of his teammate's trainer demonstrates his commitment to improving his defensive skills and solidifying his future at shortstop. This innovative approach could give Betts a competitive edge and help the Dodgers maximize his overall value.
