All seven USL1 teams won their opening game on Tuesday. The Rochester Rhinos needed a 90th-minute goal from Taiwo Atieno to tie the USL2 last-place Pittsburgh Riverhounds, 1-1, and they went on to win the shootout.
In a battle of Massachusetts teams, USL2's Western Mass Pioneers edged the Emigrantes Das Ilhas, a team of Cape Verdean immigrants from the New England Luso American Soccer Association, 3-2, in overtime.
Two games -- Aegean Hawks FC/Real Maryland and Crystal Palace Baltimore/Ocean City Barons -- were postponed because of bad weather and rescheduled for Wednesday.
