Edmonds, who has not played in an official Spring Training game since March 6 when he strained his right calf, will be eligible to come off the disabled list on April 5, as his roster move was made retroactive to March 21.
The Padres had suggested as recently as Thursday when they broke camp that they might wait until Sunday's deadline to see how Edmonds' calf responded to the rigors of playing in Minor League games as well as continued rehabilitation.
"My feeling now is it keeps Jimmy from pushing it the next few days over in Arizona," Padres manager Bud Black said. "This way, he can still work into his at-bats, get the rehab and continue to intensify his running program."
Edmonds played in Minor League games in Peoria, Ariz., on Wednesday and Thursday, going a combined 4-for-8 with a home run. He didn't play in the field in either game. Black said Edmonds didn't play in a game on Friday.
Black indicated the Edmonds will remain in Arizona until Monday when he will join the Padres at PETCO Park to work out before the home opener against the Astros. Edmonds will remain in San Diego until Thursday when he joins Class A Lake Elsinore for two games.
"He'll get a couple of games under his belt there," Black said.
By placing Edmonds on the disabled list on Friday and not waiting until Saturday or Sunday, the Padres' 25-man roster is set and they'll avoid anyone guessing who might be staying and who might be leaving.
"I just think for clarity ... so there's no confusion going into Sunday," Black said.
Edmonds was the only lingering roster decision the Padres had to figure out, as they had trimmed the roster to 26 players on Wednesday.
The Padres' 25-man roster for Opening Day includes pitchers Jake Peavy, Chris Young, Greg Maddux, Randy Wolf, Justin Germano, Joe Thatcher, Cla Meredith, Wil Ledezma, Heath Bell, Trevor Hoffman, Glendon Rusch and Enrique Gonzalez.
Position players include catchers Josh Bard and Michael Barrett, infielders Callix Crabbe, Adrian Gonzalez, Tony Clark, Tadahito Iguchi, Khalil Greene, Kevin Kouzmanoff and outfielders Brian Giles, Scott Hairston, Paul McAnulty, Justin Huber and Jody Gerut.
