Banda was recalled from Triple-A Reno on Saturday, Jack Magruder of FanRagSports.com reports.
Reno was eliminated from the Triple-A playoffs Thursday night, freeing up Banda to return to the Diamondbacks. The lefty made four starts for Arizona earlier in the second half, but he largely struggled and the team has not given any indication that it plans to deploy Banda in the rotation over the remaining weeks.
