The left-hander threw one inning in relief, his first outing since the Cactus League opener on Feb. 27. Grabow is coming off knee surgery, but had been slowed because of a tight left shoulder, which he feels was caused by throwing too much early in camp.
"Everything felt real good," Grabow said of Thursday's outing. "The ball feels like it's coming out of my hands good, my knee feels good. It was a positive day. I have to keep building off this and get ready for the season."
There are two weeks remaining, and Grabow may finish with six to seven innings total this spring. That would be the least amount he's ever thrown in Spring Training.
"As long as I'm getting my work in between and staying sharp, that's key," he said.
The Cubs have added Kerry Wood to the 'pen, which could be one of the best in the National League Central.
"This could be a great bullpen," Grabow said. "I'd love to be a part of it. I've got to finish spring and stay healthy. My whole career, this is probably the best chance I've got to get to the playoffs. I want to take advantage of that."
"I'm just trying to get the ball to [closer Carlos] Marmol -- that's our key," Grabow said.
