A.J. Burnett affectionately refers to CC Sabathia as "the big man," and paid close attention to the Yankees ace last season.

One thing Burnett noticed was the frequency with which Sabathia called on his changeup. Burnett rarely threw his and instead was mostly content with being a fastball/curveball pitcher.

"Watching CC throw last year, being a power guy and how much he uses it, kind of opened my eyes a little bit," Burnett said Monday. "Why not work on something?"

Burnett said there were times last year he was essentially a one-pitch pitcher.

"Yeah, I would say [that's true]," Burnett said. "We would throw it whether it worked or not, you got to keep chunking it and eventually we’d find it, but it could be three innings without and where you'd grind it out. It could be a more efficient three innings with another pitch."

Burnett threw 30 pitches today, 18 fastballs and 12 changeups.

Of the changeup Burnett said: "It’s going to be a big pitch for me, I think."
