Snake bites

• Trevor Cahill (right hip) will start for Triple-A Reno on Tuesday in Oklahoma City and throw around 80 pitches. His first rehab outing came Thursday in the Arizona League. D-backs manager Kirk Gibson said he wasn't sure how many more Minor League starts Cahill will need. The right-hander has been on the disabled list since July 1.

• Although the D-backs have yet to make it official, Gibson said Sunday he anticipates Brandon McCarthy coming off the DL and starting Friday in Boston.
