Wrexham drew the final game of their US tour after thunderstorms forced a two-and-a-half-hour half-time suspension.
The match against Philadelphia Union II finished 1-1 at Subaru Park.
Tom O’Connor put Wrexham ahead after 43 minutes before Jeremy Rafanello equalised for the home side with a free-kick in first-half stoppage time.
Following the lengthy delay Wrexham manager Phil Parkinson made 11 changes for a second half which produced no further goals.
The game started in extreme heat and humidity in Philadelphia before fans were warned to leave open seating areas and shelter in the concourse because of heavy rain, lightning and gusty winds.
Following the disruption of the weather and Wrexham’s wholesale changes the second half lacked rhythm, though the Welsh side came close to winning the game when defender Aaron James, making his first appearance on the tour, headed narrowly wide in the 91st minute.
