The Englishman scored on a free kick from an impossible angle to give United a 2-0 lead after 30 minutes. The Lions dominated the match with a 16-4 edge in shots but could only manage one goal from Dom Dwyer in the 63rd minute.
O'Connor and Dwyer fumed about the Rooney goal.
O'Connor said the goal should have been called off for a foul by D.C. defender Frederic Brillant on Brian Rowe as Rooney's ball curled over the Lions keeper. Dwyer argued he didn't foul Rooney on the play that led to the free kick, terming the decision by referee Armando Villarreal "unbelievable."
O’Connor criticized the refereeing crew for not going to VAR -- and then ticked off games when Orlando City was on the wrong side of controversial calls since he took over.
“The foul on Brian Rowe was so obvious,” O'Connor said. “It goes to VAR, everybody can see it. For some reason, we don’t… what’s the point in having VAR? He didn’t even go and look at it. Yet, everyone can see that it’s a foul. For us, we’ve had it, since I’ve been here, we’ve had it in game after game."
Rooney put Dwyer in his place, saying it didn't matter that didn't get him.
"I see him coming and I got out of the way because if I didn’t, it could’ve been a serious injury,” he said. “As the referee said, it’s intent. I’m not stupid enough to stand in there and let him try to take my knee off.”
