The team's fourth consecutive 1-0 win sees NYRB II into a share of the USL Eastern Conference lead.
In a match that followed much the same script as NYRB II's last outing (against Bethlehem Steel), the New York Red Bulls' USL team scored an early goal and then subsided into a mostly-even game that they won, 1-0.
Harrisburg City Islanders were defeated by a thundering Sean Davis strike that turned a loose ball in the box into a net-ballooning match-winner.
Hapless Harrisburg is a high-scoring team by the standards of this year's USL Eastern Conference, and created several chances to equalize - including a Craig Foster header that beat NYRB II 'keeper Kyle Reynish but not the offside flag.
