Aardsma originally expected to begin playing catch shortly after he was able to put aside his crutches and could put his full weight on his hip. But he's been walking for a week now and still hasn't received the green light to start playing catch.
"Nothing new," the 29-year-old said Tuesday. "I'm just doing my work. I just keep my head out of it and try to get better every day and not worry about when I'm throwing. That's just where I'm at. It will happen eventually and that will be great."
Aardsma has said all along that he'd rather go slowly and be ready to pitch at season's end rather than push for an early return that would set him back further. But initial suggestions that he could be ready to pitch in games by mid-April clearly seem overly optimistic now.
Manager Eric Wedge said there is no timetable on Aardsma's return.
With Aardsma out, the club continues looking at closer options. Returning setup man Brandon League seems like the favorite, with former Orioles closer Chris Ray and ex-Red Sox reliever Manny Delcarmen in the mix as well.
Ray has pitched two scoreless innings this spring and will throw in a simulated game Wednesday. Delcarmen has made four Cactus League appearances and surrendered four walks, two hits and two runs, though he threw a 1-2-3 eighth with a strikeout in Tuesday's 1-0 victory over the Giants.
Rookie Josh Lueke has been one of the more impressive relievers in camp so far, with four scoreless innings with just two hits and no walks, but the Mariners have expressed reluctance to throw a youngster into the closer role right off the bat.
