Cubs place Miles on DL; Fuld called up

Ramirez, Guzman nearing Minors rehab assignments

PITTSBURGH -- One day after testing his hyperextended right elbow by hitting off a batting tee, Cubs infielder Aaron Miles was placed on the 15-day disabled list on Monday, retroactive to June 21.

"I just hope it gets better soon so I can possibly go get some at-bats somewhere," Miles said. "But I've just got to get ahold of it and make sure it's not something too serious."

Miles didn't take batting practice Monday.

Manager Lou Piniella admitted the club didn't want to say anything about Miles' availability until now because he didn't want the White Sox to know for this past weekend's series. Piniella hoped the elbow would heal in a hurry, but it was a mutual decision to send Miles to the DL.

Replacing Miles is Sam Fuld, who was brought up from Triple-A Iowa. Fuld was hitting .286 and stole 20 bases for the Pacific Coast League club. Fuld found out about the callup Sunday night. He previously played for the Cubs in September 2007, spending time mostly in right field.

But Fuld could start in the outfield as soon as Tuesday, as Piniella said Milton Bradley may take a couple days to work with hitting coach Von Joshua, specifically with his hitting on the left side. Bradley is hitting just .195 as a left-hander this season.

In other injury news, both Angel Guzman (strained right triceps) and Aramis Ramirez (shoulder) will receive Minor League rehab assignments in a few days. Guzman threw a bullpen session Sunday, and Piniella anticipates the reliever pitching Thursday and again on Saturday before reactivating him when he's eligible on July 6.

As for Ramirez, the third baseman will take batting practice with the team for all three games in Pittsburgh. Piniella expects Ramirez will go out to his rehab assignment Thursday. Ramirez said he is still on target, but didn't want to commit to a timetable for his return.

Ramirez hasn't played since May 8, and Piniella trusts the veteran's ability to decide for himself.

"He'll know -- he's a professional hitter," Piniella said. "He can tell us more than we can tell him, quite honestly. He's worked hard, to his credit. We thought it'd be about two months. That's going to be about the timeframe."
