Mound work first step in long rehab for Greinke

Mound work first step in long rehab for Greinke

CINCINNATI -- The Brewers expect injured starter Zack Greinke to begin throwing off a mound this weekend in Cincinnati or early next week in Milwaukee, but he's still weeks away from being activated from the disabled list and could miss all of April, manager Ron Roenicke said.

Greinke is on the DL with a cracked left rib, and his first mound session would represent a significant first step in a relatively long process. Other pitchers throw about 10 days of bullpen sessions before beginning to face hitters, and then Greinke would have to build his pitch count. In Spring Training, starters throw about 30 pitches in their first outing and increase in increments of 15 pitches per start every fifth day.

"It may be a little longer than what I thought it was going to be," manager Ron Roenicke said. "I figured by now that he would be throwing [off a mound] a while ago. But he still felt [discomfort] in his ribs, and they didn't want to do anything with him until that was gone."

As of Wednesday, Greinke was still building arm strength by throwing on flat ground.

Barring rainouts, the Brewers can get by with four starters in April except for April 6, 16 and 26.
