A first-half own goal from Ethan White proved decisive in a match that Palace dominated before their momentum stalled slightly after a raft of half-time changes.
Pulis told the Palace website: “It was pleasing. We worked very hard, they made us work very hard. Full compliments to Philadelphia because it was a very competitive game.
“First half, truthfully, we should have scored quite a few goals and that’s not criticising them [Philadelphia] at all, that’s Bolasie, Puncheon, Chamakh and Gayley all missing really good chances that they should have scored from.
“In the second half we made lots of changes and it was a good work-out for us. That’s as hot as it’s been for the lads as well.”
After drawing 2-2 with Columbus Crew in the opening match of their American tour, Pulis was happy to see his squad gain more game time against a side who are fifth in the MLS Eastern Conference.
“As I’ve said before, the results don’t matter too much, it’s about getting the players fit,” Pulis said.
“The fitness levels I think are pretty good and the lads just need more games now. The group will have more game time against Richmond.”
Palace conclude their tour with a game against Richmond Kickers on Monday July 28.
