Jake Westbrook, six weeks removed from Tommy John surgery, is doing well in his rehab, according to MLB.com. "It's stable," Westbrook said of his elbow. "I'm pleased with it. It's still a little achy and a little sore. Now it's a matter of letting it heal and doing some rehab."Westbrook will likely miss the first half of next season, and therefore is likely not worth really thinking about in terms of fantasy production until late in 2009.
