Alex Neil’s side opened the scoring on the stroke of half-time when Jack Clarke was fouled in the penalty area and Ross Stewart converted the subsequent spot kick.
The hosts drew level just after the hour mark when Bailey Wright conceded a penalty and Sean McConville sent Anthony Patterson the wrong way, before substitute Kodede Adedoyin made it 2-1.
The Black Cats have one more friendly ahead of their Championship opener against Coventry next weekend, with the team set to travel to Hartlepool on Monday.
Here, though, we take a look at the best pictures throughout the day courtesy of our photographer Frank Reid:
