Jose Berrios is using Major League Baseball's hiatus to work on two of his pitches.

The 25-year-old Minnesota Twins' ace is trying to change the trajectory of his changeup and curveball. His best pitch is his four-seam fastball.

"Right now, I am focusing on throwing the changeup towards the glove side, which would be on the side outside the right-handed hitter," Berrios said. "As it naturally runs for me, it would be on the arm side, from the middle towards the bottom. I want to improve it towards the glove side.

"I'm also working on a curveball, like if I'm facing a right-handed hitter, it goes over the hitter and falls for a strike. I know those are efficient pitches and I want to add them to my repertoire. The changeup comes out in a way that's natural to me, so I want to work it elsewhere."
