CLEVELAND -- Veteran right-hander Aaron Harang did some running and tests on Monday, and the Mariners plan on starting him Tuesday in Anaheim after he missed his last outing in New York due to lower back stiffness.
Harang, 35, also threw a bullpen session on Sunday and said all went well.
"It felt good yesterday," he said Monday before heading out with trainer Rick Griffin for his follow-up. "Now I've just got to go run and test it again."
Manager Eric Wedge said things are progressing as needed.
"He's still lined up for Tuesday," Wedge said. "We anticipate everything being fine and he'll be good to go."
The biggest test was the bullpen session.
"It went pretty good," Wedge said. "You don't want to go too far with it, but he had a good work day and was even getting off the mound and fielding some bunts and things. So it was a pretty good test yesterday."
Harang is 1-4 with a 7.30 ERA in five games since being acquired by trade from the Rockies on April 12. He began slowly after not pitching for several weeks, but had back-to-back quality starts before his Thursday outing against the Yankees was scratched.
