Free-agent pitcher Mark Mulder could be a potential addition to Oakland's pitching staff before the end of spring. He has had shoulder issues for several years, and has been pitching in Arizona in hopes that he'll be able to work out for interested teams in the near future. The Athletics are expected to be one of the interested teams when Mulder finally opens up a workout to suitors. "I'd love to be out there, but what I was doing the last couple of years wasn't fair to me and it wasn't fair to the Cardinals, and I'm not going to do that to another team," Mulder said. "I'm not going to say I'm ready to roll and sign with someone until I can repeat side sessions and repeat them again with no issues, no doubt in my head, no setbacks."
