It's all about Clayton Kershaw for now as the Dodgers try to finally get on a roll in Philadelphia this weekend.The Dodgers' rotation, generally viewed as the backbone of the team, is intact (pending Chad Billingsley's slow rehab) now that Hyun-Jin Ryu has returned and Kershaw has been healthy for a few weeks.Now, the question is whether Kershaw's last start – in which he lasted 1 2/3 innings at Arizona and allowed seven runs – was just a bad day or signaled a mechanical issue.
