PEORIA, Ariz. -- Jim Edmonds' readiness for the Padres' March 31 opener with the Astros is in question because of a right calf strain that will likely put him on the shelf for two to three weeks.

Don't, however, question the toughness of Edmonds. He could still be the Padres' Opening Day center fielder.

"Hopefully people don't count me out," Edmonds said at his locker on Saturday. "It would be a bad mistake."

Edmonds injured the calf on Thursday and a MRI revealed the severity on Friday.

"It's just an unfortunate situation and I'm really not excited about it, to say the least," Edmonds said. "I've got to deal with it. It's a lot better today. I'm hoping that it's a speedy recovery. It's a bad situation for me. I'm kind of bummed out right now.

"For something like this to happen, something simple, I got my foot stuck in the box a little bit and felt a little twinge. Sometimes early in spring you put yourself in situations you're not used to being in and things happen. It's pretty disappointing right now. Especially 'cause I'm with a new team. Not to mention as hard as I worked and with a new team, it's doubly disappointing."

The Padres acquired Edmonds in a Dec. 15 trade with the Cardinals for infielder David Freese and cash considerations to replace Mike Cameron in center.

Edmonds said he would spend the next two weeks getting a lot of treatment, lifting weights and doing some cardio.

"Just really get ready like I would if I was playing, but just not be able to play," he said. "They're going to give me like a week of just not really trying to do much because if this thing keeps aggravating it's going to be later on. Right now, I'll go four or five days with not doing anything but treatment. It will be fine."

Meanwhile, manager Bud Black is forced to make plans in Edmonds' absence. He listed multiple center-field candidates -- Scott Hairston, Jody Gerut, Callix Crabbe, Jeff DaVanon and Chip Ambres. Crabbe, a Rule 5 Draft pick, got the start on Saturday against the Rangers. If Edmonds' injury lingers, the Padres could trade for a center fielder.

"I wish I had a crystal ball," Black said, after asked whether Edmonds would be ready when the season starts. "I don't know. There's a chance. The early diagnosis is two, maybe three weeks. That gets it close, gets it right there."

If Edmonds, who turns 38 in June, is healthy all year, Black said, "Jimmy would like to play 135-145 games, maybe more."

Added Black: "I'd like him to play. He's a good player. We're hoping Jimmy makes a speed recovery. I think walking is a little bit troublesome for him right now. His spirits are OK. He's bummed cause he was feeling so good physically and to have this pop up is frustrating for him."

In 2006, Edmonds missed most of the final six weeks of the season with dizziness from a concussion after running into the wall trying to catch a ball. He had surgery during the offseason on his right shoulder and to repair ligament damage in his big toe. He appeared in 117 games last season.

"Last year I really wasn't 100 percent, but I played hurt," Edmonds said. "That's what people don't understand, I'm going out there regardless of how I feel. That's my job."

Maddux breezes: Greg Maddux said he was fine after getting hit in the left shin by Jarrod Saltalamacchia's ground ball in the second inning in Saturday's start against the Rangers. Maddux, a 17-time Gold Glove winner, still made the play and threw out Saltalamacchia for the final out of the inning.

He then came back to pitch a scoreless third before retiring for the afternoon, having allowed one run on one hit with a strikeout. Maddux had an icepack on the shin in the clubhouse but doesn't expect any problems. He said his the overall physical conditioning of his legs has been a highlight for him this spring.

"My legs feel better this spring," Maddux said. "My arches hurt last year but they've been fine this year. It has been easier for me to run."

Staying home: Right-hander Tim Stauffer has been scratched from the China trip for exhibition games against the Dodgers next week because of soreness in his shoulder.

"He's got a little bit of a cranky shoulder," Black said. "He was to pitch in Beijing, but it looks as if we're going to remove him from the trip. We'll shut him down a few days and then bring him up to speed."

Stauffer had appeared in one Spring Training game, allowing four runs, three earned, on four hits, including two home runs.

Sinisi injured: Padres outfielder Vince Sinisi suffered a fractured right wrist in the sixth inning of Saturday's game. Sinisi was hurt trying to make a diving catch on Ryan Roberts' bloop single. Sinisi is in camp as a non-roster player and was most likely expected to start the season at Triple-A Portland. The Padres weren't sure how long he will be sidelined.

Friars notes: Infielder Brian Myrow, who hit .354 in 2007 for Triple-A Portland, is hitting .545 in his first eight games with four walks for a .688 on-base percentage. ... The Padres' .340 batting average and .526 slugging percentage entering Saturday topped National League clubs, while their .429 on-base percentage led the Majors. ... The Padres are 3-0 against National League West opponents.

Up next: Left-handers Randy Wolf and Wade LeBlanc are each scheduled to throw three innings Sunday against the White Sox at Peoria Stadium. Right-hander Jose Contreras will start for the White Sox.
