Davis was outrighted to Triple-A Indianapolis after clearing waivers Sunday, Kevin Gorman of TribLive.com reports.
Davis won't immediately report to Indianapolis, as the Pirates plan to keep him on their taxi squad while the team heads to the West Coast for a seven-game road trip during the upcoming week. The 32-year-old didn't make any appearances for the Bucs during his brief stay on the active roster before he was designated for assignment Friday.
