With the scoreline reading 2-0 to the Red Bulls, Saborio gave RSL some hope when he sent Red Bulls keeper Luis Robles the wrong from the penalty spot after Olmes Garcia had been felled in the area by Markus Holgersson on the stroke of half-time.
Saborio then levelled the match in 80th minute when he tucked home Garcia's deft ball with a first-time effort following a clever run from Luis Gil.
Just two minutes later and RSL were ahead when Saborio completed his hat-trick by producing an audacious toe-poke after being fed by Joao Plata at the top of the box.
Unfortunately for the visitors, former Salt Lake forward Fabian Espindola scored his second of the evening from the penalty spot before a late Dax McCarty header gave New York the win.
Nevertheless, Saborio was rewarded for his brilliant performance to become the second RSL player to get the nod from the North American Soccer Reporters following Garcia's prize in Week 15.
