Diamondbacks right-hander Brandon Webb is changing his arm slot after a visit with a rehab specialist.

Webb remains on the disabled list as he continues his comeback from shoulder surgery.

"I have to retrain," he told the Arizona Republic. "Even though I'm almost 10 months out of surgery and I've been throwing for five months, I've been almost wasting my time throwing bad."

Webb said he was told his arm slot was at 110 degrees, which is higher than it was before he underwent surgery.
