Rich Harden pitched three innings on Saturday. He didn't pitch well, but he's working on fixing mechanics disrupted by his injuries:

More importantly, Harden is feeling fine physically and is confident about a minor mechanics adjustment he made in Saturday's 7-6 victory over the Cubs at Phoenix Muni Stadium.

"It's something I used to do a few years back," Harden said. "With injuries, you kind of start pitching away from pain. Your body changes its mechanics. We just kind of figured out something that's pretty big that I used to do with my front side."

In recent days, Harden worked on changing the placement of his left arm and hand position with first-year bullpen coach Ron Romanick, who's familiar with Harden because he was the A's roving pitching instructor for nine years.

"I just reminded him of what he used to do," Romanick said.

His continued health is good news for Oakland.
