MILWAUKEE -- Brewers general manager Doug Melvin and manager Ron Roenicke planned to meet Tuesday to set plans for a flurry of changes to the team's starting rotation in the coming weeks. Those changes should begin later this week with the return of right-hander Shaun Marcum, who made a third rehabilitation start Monday for Class A Wisconsin and pitched well, allowing a run on four hits in six innings, throwing 50 of 71 pitches for strikes. Assuming no setbacks, Marcum, who has missed more than two months with a stiff right elbow, will slide into the Brewers' rotation on either Saturday or Sunday in Pittsburgh, depending on whether he wants the extra day of rest. Asked whether someone would come out of the rotation for Marcum or whether the Brewers would stick with six starters, Roenicke said, "We need to talk about that. We've talked about both -- we've got plans for going with six, and we've got plans to make it five. We'll still need to talk about that."
Roenicke said that, "right now," the Brewers are inclined to keep left-hander Randy Wolf in the rotation, but, "that will be something we talk about." Wolf is 3-10 with a 5.69 ERA after losing to the Phillies on Sunday. Melvin and Roenicke will discuss removing a number of others, including right-handers Mike Fiers and Mark Rogers, prospects who are nearing their innings limits. Ditto for righty Marco Estrada, who is under watch because he is in the midst of his heaviest workload since 2009. Besides Marcum's return, the Brewers are expected to add two prospects -- right-handers Wily Peralta and Tyler Thornburg -- before the end of the season. Each could make a start or series of starts to help the team make decisions about its 2013 pitching rotation. Those promotions are more likely to come after rosters expand beginning Sept. 1. Triple-A Nashville plays its final game on Sept. 3.
