"Johnson won't pitch during Rockies series

Randy Johnson and Madison Bumgarner sat at adjacent lockers, wearing twin icepacks on their left shoulders, and shared a laugh.

Johnson is 46, he has a torn rotator cuff and he's trying to make it back for one last fist pump. Bumgarner is the Giants' 20-year-old top prospect, with all the benefits of youth.

"I go out there and I pretty much get loose from the first throw," Bumgarner said.

Better not tell that to the Big Unit. As Johnson said after throwing two simulated innings Monday, "I don't think with another one of these, I'll go from this to 25 again and knocking the catcher over."

Johnson owned eight major league wins when Bumgarner was born on Aug. 1, 1989. Now the left-handers from two generations will be bullpen mates, once Johnson is activated from the 60-day disabled list. Bumgarner officially joined the 'pen when Tim Lincecum assumed his place in the rotation Tuesday.

Johnson was encouraged after throwing batting practice — including an accidental plunking of John Bowker — and saw no reason why he couldn't be activated today; Giants manager Bruce Bochy had a different opinion, though, saying the Big Unit wasn't a candidate to be activated during this three-game series against the Colorado Rockies.

But Johnson said he's ready to go, and Bumgarner can't wait to see him in action."
