Grabow making progress in his rehab
DENVER -- Cubs reliever John Grabow threw off the mound Friday for the second time, throwing 15 pitches, and said he was making progress in his rehab from a strained left knee.
Grabow threw fastballs and sliders during his session at Coors Field.
He's been on the disabled list since June 29.
"He's been slowly getting better," Lou Piniella said.
