Marcum to make Class A rehab start Thursday

MILWAUKEE -- Shaun Marcum's long trip back to the mound for the Brewers will continue on Thursday, when he makes his first rehab start for Class A Wisconsin.

Milwaukee manager Ron Roenicke announced the news on Monday, one day after Marcum threw his first simulated game since being scratched from his scheduled start on June 19 with right elbow tightness. At the time, Roenicke expected Marcum to miss a start or two. But after it took weeks for Marcum to even be able to throw off the mound, he went from the 15-day disabled list on June 23 -- retroactive to June 15 -- to the 60-day disabled list on July 29.

Before the injury, Marcum was 5-3 with a 3.39 ERA in 13 starts, including a three-start winning streak in late May and early June.

Thursday will be Marcum's first game since he allowed two runs in 7 2/3 innings to the Royals on June 14. Roenicke said Marcum will throw 45-50 pitches against Cedar Rapids, and the 30-year-old right-hander said on Sunday that he anticipated needing only two Minor League starts before returning to the Brewers' rotation.

"We're discussing that," Roenicke said. "We have a plan of what he's going to do. We haven't finalized it yet."

Claimed off waivers, Izturis in playoff race with Nats

MILWAUKEE -- In a move that allowed the Brewers to take their first live look at Jean Segura, infielder Cesar Izturis was claimed off waivers by the Nationals on Monday.

Izturis made the team as a non-roster player and played in 57 games for Milwaukee. He started 40 of those games, splitting time at shortstop with Cody Ransom for much of the season, and batted .235 with 11 RBIs and two home runs.

Milwaukee manager Ron Roenicke said he had a chance to talk with Izturis before he left to meet up with his new team. And although he didn't want to speak for general manager Doug Melvin in terms of why the move was made, Roenicke said it was a transaction that helped all parties.

"You can ask Doug about why he did it, but it's a veteran player," Roenicke said of Izturis. "He's got a chance to go with somebody who's in first place. ...

"[Melvin] doesn't want to hold anybody back, which is really good for the player to know that a general manager will do things for a player. It's pretty nice to have."

Entering Monday's action, the Nationals were leading the Braves by three games in the National League East. Meanwhile, the Brewers trailed their opponent on Monday night, the Reds, by 17 1/2 games.

From the Brewers' perspective, Izturis' departure gives the club a chance to look ahead to the future. Along with Segura's callup on Monday, Roenicke mentioned infielder Jeff Bianchi, who played in seven games in Milwaukee this season, as another player who might find himself in the Majors come September.

Last call

• Aramis Ramirez made his second straight start on Monday after the Brewers third baseman missed two consecutive games with a sore left wrist. Ramirez received a cortisone shot on Thursday, and manager Ron Roenicke said his status will be handled on a day-to-day basis.

"He's going to let me know [how he feels]," Roenicke said. "He was good yesterday, and he'll continue to let me know how he's doing."

• The Brewers will host a PLAY Campaign event on Tuesday at Miller Park, in an effort to teach children the importance of being healthy and active. Starting at 10:30 a.m. CT, outfielder Nyjer Morgan and members of the Brewers' training staff will work with about 100 local kids, delivering various messages to them about healthy lifestyles. At noon, MLB Commissioner Bud Selig will speak to the children and take questions before giving a presentation with the National Baseball Hall of Fame and making an announcement related to the event.
