The Bulls started the game in a positive fashion as Kljestan had a go from distance, only to be denied by a sprawling Tally Hall in the Orlando goal.
Carlos Rivas registered Orlando's intent early on too, as he forced a good stop from the New York keeper from the centre of the box.
Kljestan was to return to haunt Orlando, however, and he gave the Bulls a 1-0 lead with a bullet of a shot that proved too much for a helpless Hall.
Orlando's chances of getting back into the game took a major dent just over 10 minutes later, when striker Larin was shown a straight red card following a challenge that showed too many of his studs.
Heath then followed Larin into the tunnel, before producing a full-blooded attempt to reinvigorate the fans on his way, but Grella netted a second in the dying stages to dash any hopes of a comeback.
