CHICAGO -- Phil Humber added a cutter to his repertoire during the past offseason and in Spring Training, but only used that pitch a handful of times during Saturday's victory over the Rays. So, a side session under the watchful eye of White Sox pitching coach Don Cooper on Monday was focused on getting a better feel for that particular pitch.
"It's a new pitch for me, so it's a work in progress," Humber said. "I toyed with the grips and things like that. It turned out good. He showed me what he likes, and I tried that and got some good results out of it. Hopefully, it will be something I can use in the game Friday, because it really wasn't much of a factor the other day.
"I threw some good ones [in Spring Training], but I got in the habit of getting on the side of it and trying to make it do something instead of just staying on top of it and trusting the grip. That's why we worked on the grip. It's the most important part."
Humber believes the addition of a cutter can help him expand away from righties and into lefties, while also balancing out his changeup and curve.
