SCOTTSDALE, Ariz. -- Second baseman Rickie Weeks returned to action on Saturday, but the Brewers remained in wait-and-see mode regarding injured left-hander Chris Capuano and sick shortstop J.J. Hardy, according to assistant general manager Gord Ash.
Weeks had not played since injuring his right hand sliding headfirst into second base on March 16, but participated in a Minor League game on Saturday and went 2-for-4 with a walk, a hit by pitch, a double, a triple and three runs scored. He was also cleared to man second base and played four innings of defense.
Following an 8-1 loss to the Giants in the day's "A" game, manager Ned Yost said that he expected Weeks back in the big league lineup on Sunday against the Diamondbacks.
Hardy, who has been battling a stomach ailment, underwent a series of medical tests on Friday, but the team will not have results until Monday, Ash said. He was allowed to swing a bat Saturday but is easing slowly back into action.
The Brewers worry that Hardy is suffering from something more serious than the flu.
"I feel normal, but I lost 10 pounds," Hardy said on Saturday morning. "I think they want me to take it easy, because I'm dehydrated. They won't want me to go out, get my pulse too high and not be able to recover from that. ... I feel like I could probably do everything."
Hardy last played against the Mariners on March 16 and went 2-for-2 including a home run off Seattle ace Felix Hernandez. He's not worried about missing a week's worth of at-bats.
"It felt like I was ready to break [camp] that day," Hardy said. "I'm not worried about being ready. I think the doctor has a pretty good idea of what's going on, he's got it under control and it's a matter of putting weight back on."
Capuano underwent an MRI scan on his sore elbow on Thursday, but the team is waiting for Dr. William Raasch to arrive for an examination before revealing the results. Raasch's Friday night flight was canceled because of a snowstorm in Milwaukee, but he was scheduled to arrive at some point on Saturday, and Ash expects to provide some information on Sunday.
No matter the diagnosis, Capuano, who complained of soreness in his surgically-repaired left elbow on Monday, is not expected to begin the season with the Brewers. He would either be placed on the disabled list or be optioned to Triple-A Nashville.
