What they’re saying

“I didn't perform the way that I want to. I didn't perform the way that I know I can. Entering the offseason I was [ticked] because that's the season I put out to the world. It was a long offseason, a lot of nights thinking about it.”

“I have peace in my mind that I know I'm really good at baseball, but it [ticked] me off that I didn't play that way. It's not about there being doubt that I'm good or not, or that I know I can hang. I know myself. I know who I am as a player. And I know I'm really good when I step onto the field.”
