The Philadelphia Union received its draw for the fourth round of the US Open Cup, and will host the winner of Harrisburg City Islanders vs. Reading United on June 14.
Harrisburg City Islanders defeated Ocean City Nor'easters, a PDL team, in the second round of the tournament in penalty kicks on May 17. The two teams played to a scoreless draw through the first 120 minutes, but the Islanders prevailed in penalties 6-5. Playing the Union would be a homecoming of sorts, as the Islanders were the Union's USL affiliate from 2010 until 2016, when the Union created Bethlehem Steel FC as its affiliate.
