Liriano has been tabbed as the Pirates opening day starter and is hoping for consistency this spring.
"My change up, my slider, I think they're there. I'm not worried about that all," Liriano said.
He is hoping to not lean as much on his off speed stuff this season.
"(This season) I want to throw more of my fastball, more of my two-seamer, so I can go deeper into the game," Liriano said. "Hopefully I can get more ground balls than last year.
"I'm trying to be more consistent and stay healthy, and we'll see what happens. I've been hurt a couple times, and that's been a part of my ups and downs."
