Cavanaugh is not in the Giants' starting lineup against the Diamondbacks on Friday, Susan Slusser of the San Francisco Chronicle reports.
The lefty-hitting Cavanaugh will be on the bench for Friday's game while the Diamondbacks send southpaw Kohl Drake to the mound. Andrew Knizner will start behind home plate and bat out of the cleanup spot while forming a battery with Giants right-hander Blade Tidwell.
