Walden said he played long toss from 200 feet on Friday in Chicago with no pain.
"Everything was good," Walden said. "I'll play long toss again [on Saturday] and I should be back on the mound soon. [The test] is going to be getting on the mound a couple days in a row to see how it feels, but right now it's going great."
Angels manager Mike Scioscia confirmed the plan to keep Walden throwing long toss through the weekend series and hopefully get him on the mound Monday. Getting Walden back into a bullpen that's seen a lot of work recently is obviously something the Angels could really use heading into the final two months of the season.
"With Scott Downs and Jordan out, we've had to adjust some things," Scioscia said. "Any depth we get is going to be important and Jordan is part of that."
