Manager Ken Macha indicated he would like to have Edmonds available on Sunday, particularly with outfielder Carlos Gomez out with a strained left knee.
"We talked to [Edmonds], and he's feeling much better," Macha said. "He'll hit in the cage [Saturday]."
Edmonds did take some swings on Friday as well, but the injury prevented him from doing much more.
"I just took a couple of swings off a tee, but I couldn't throw," Edmonds said. "I can't do any running or throwing yet. I can go side to side, but I can't [throw overhand], so I had to really limit what I did and just let it try to heal."
Pinch-hitting is likely not an option on Saturday, Macha said, especially with the hard-throwing Mat Latos on the mound for the Padres.
"I would doubt [Edmonds will pinch-hit], but I don't know. We'll see how he hits in the cage," Macha said. "I'd like him to be able to play [Sunday], but then we've got Monday off, so we'll see."
Edmonds suffered the injury in Wednesday's game stealing second base in the 13th inning. His slide into second tweaked his back and caused the soreness.
