Axford tweeted Friday that his son left the intensive care unit, after three weeks and three days, but still has a "long road ahead." His son had surgery last Monday in Denver for an infection in the foot.
"It's a day-to-day-type situation," manager Walt Weiss said. "He's been staying in shape and throwing, keeping his arm in shape."
• Righty Scott Oberg entered Sunday having thrown 2 1/3 scoreless innings after being called up to replace Axford. It's been a whirlwind for Oberg, whose 2014 season at Double-A Tulsa ended early because of a shoulder surgery that, luckily, could be rehabbed fully during the winter.
"My arm is in really good shape right now, especially after all the surgery and rehab, and hopefully it will get stronger throughout the season," Oberg said. "I feel I'm where I was before I got hurt."
• Left fielder Carlos Gonzalez went into Sunday hitting .231 with one home run. Gonzalez tends to go on torrid streaks, however. Was his performance Saturday, when he drew a walk and hit a hard line drive to center, a sign that the streak is about to come?
"Those are good signs that he's starting to get locked in again," Weiss said.
Gonzalez admitted that his timing has been not quite where he wants it, but he feels it'll come.
"I'm looking to make solid contact, and when it happens a lot of those balls are going to go over the wall," Gonzalez said. "It's something we don't look for. Just good swings -- when you feel consistent with your swing a lot of extra bases and home runs are going to come.
"I can feel when I'm in the zone and hitting the ball hard. My swing is good. It's just timing. I've been out front often, but the more I play the more I'm going to see the ball better."
