Hammel's next outing will be pushed back to Sunday against the Royals because he's dealing with a fingernail issue, ESPN Chicago's Jesse Rogers reports. The Cubs apparently don't believe the issue is serious, as they're merely swapping Hammel and Tsuyoshi Wada in the rotation, moving the former back one day. The situation is still worth keeping an eye on, in case Hammel's finger turns out to be worse than expected.
