After Quantrill was lifted with one out and two runners on base in the fourth, Schwarber greeted lefty Austin Cox by sending a 3-2 curveball over the wall in right for his fourth multi-homer game of the season.
With “M-V-P! M-V-P!” chants ringing down from Phillies fans in the fifth, Schwarber launched a three-run, opposite-field drive off Cox to put Philadelphia ahead 15-3. In the eighth, Schwarber hit a three-run shot to right off Wander Suero to make it 18-4.
Schwarber popped out in the eighth to short left field with third baseman Vidal Bruján on the mound.
After Philadelphia starter Aaron Nola (3-7) labored through a three-run, 37-pitch first inning, Schwarber, J.T. Realmuto and Max Kepler homered in the bottom of the inning. Bryce Harper also went deep for Philadelphia, which had 20 hits and 19 RBIs.
