Center fielder Mark Kotsay, out since Monday with the same type of lower-back spasms that cost him chunks of playing time in the past two seasons, didn't hear anything new on Thursday when relayed the results of his MRI exam. Thus, he's flying to Los Angeles early Friday, MRI films in hand, in search of a fresh medical perspective. "The radiologist here said I have a herniation, L3-4 [lumbar vertebrae]," Kotsay told MLB.com by phone on Thursday afternoon. "It's kind of old news; we've had this and dealt with it the last two seasons. So I'm going to go see a doctor in L.A. and see what he has to say about it." Kotsay then went out of his way to make sure his trip wasn't perceived as a sign of displeasure with Oakland's medical staff. "I guess you could call it a second opinion, but it's nothing against our guys at all," he said. "It's more just me wanting to get as much information as possible and try to make sure everybody's on the same page as far as what's the best way to handle treating it."
