Kemp will start in left field and bat ninth Monday in Game 2 of the NLDS versus the Dodgers.
With Harrison Bader (groin) out of the lineup, Brandon Marsh will shift to center field and Kemp will enter the fray in left field. It will be the postseason debut for Kemp, who slashed .234/.298/.411 with eight home runs in 62 regular-season contests for the Phillies.
