Cunningham is expected to be called up Wednesday, Alden Gonzalez of MLB.com reports.
With outfielders Daniel Nava and Shane Robinson dealing with injuries, the Angels are looking to add some outfield depth. There's currently no news of either of those players heading to the DL, so it's unclear exactly how much playing time Cunningham would see if he is called up. He slashed .293/.389/.401 with four homers and 14 steals in 65 games at Triple-A this year, but has never proven himself capable of hitting big league pitching.
