"It went OK," Greinke reported. "I threw and I was healthy, so that's good. I've got another [simulated game], and then I'm going to throw a game. It was nothing special, it was in the batting cages, so you couldn't really get as good a feel for it as you normally would."
Greinke has been on the DL since March 26 with a fractured left rib.
"It's just getting ready," Greinke said. "You've just got to do that to get ready, and then I've got another one and then a couple of games, and hopefully I'll be ready then to come back."
"Greinke threw, basically, a simulated game in their batting cages," Brewers manager Ron Roenicke explained. "He threw the ball really well. We called balls and strikes and he was out there without a screen in front of him, so he got after it. He threw 25 pitches with no break. The next time he does it he will have a break in between. It was good.
"He's trying to come real fast, and I think trainer Roger Caplinger will have to look at that so we just don't let him go full-go, because that's what he'd like to do and I think we have to watch that a little bit. If he comes out on Wednesday and he is not sore I'll be pretty impressed, because he wasn't holding back on anything."
Greinke is scheduled for one more batting-practice session before being sent on a Minor League rehab assignment, likely with Triple-A Nashville.
