SCOTTSDALE, Ariz. -- D-backs manager Kirk Gibson watched Tyler Skaggs throw a bullpen session the other day and knew right away the left-hander was not playing around.
"He was going at it pretty good his last bullpen session, and I was like, 'You've got to take it easy,' and he said he's been throwing," Gibson said. "He's trying to win a job. For me, you don't want him to overdo it and hurt himself, but at the same time, you want to see what he's got."
Skaggs is battling for the fifth spot in the rotation with Patrick Corbin and Randall Delgado, and he has come into camp like a man on a mission.
Skaggs was 185 pounds at the beginning of last spring and 190 at season's end. After an offseason of workouts, he is now at 213 pounds and he started his throwing program two to three weeks earlier this year to get ready for camp.
"I worked really hard during the offseason lifting weights, trying to get stronger," Skaggs said. "I came to camp ready to go. I'm not trying to get into the swing of things, I'm trying to win a spot. I wanted to come in here with my arm ready to go."
