Marcum to throw off flat ground Saturday

CINCINNATI -- Injured Brewers right-hander Shaun Marcum is scheduled to "let it go" during a 25-30 pitch, flat-ground throwing session on Saturday, manager Ron Roenicke said.

Marcum may have to throw two such sessions before pitching off a mound, though that plan is in flux, Roenicke said.

"I know Marcum wants to push it a little, so we'll see," he said.

Marcum has yet to throw off a mound since developing tightness in his right elbow following a June 14 start at Kansas City. He was subsequently placed on the disabled list.

Even if his flat-ground sessions go well, Marcum is a few weeks away from active duty. He will have to throw a series of mound sessions before a Minor League rehabilitation assignment.
