Closing the week with a bogey-free four-under 67, Bhullar finished at 15-under 269 in tied 10th place.
India's other man in the field, Anirban Lahiri suffered a double bogey on the 16th in his 69 that saw him finish at 10-under in tied 26th place.
The best Asian Tour finisher was Jbe Kruger (68) in the eighth place.
Nick Watney flirted with the possibility of a 59 as he came to the 18th tee at 11-under needing a birdie at the par-71 Mines Resort and Golf Club Course.
He ended with a bogey instead and carded 61 but that fetched him the title ahead of defending champion Bo Van Pelt (66) and Robert Garrigus (66), both of whom finished a stroke behind at 21-under.
Tiger Woods (63), Brendon de Jonge (66) and Chris Kirk (67) tied for fourth at 19-under.
Bhullar, who shot 65, 72, 65 in his first three rounds, birdied seventh, 11th, 15th and 17th and missed a handful of other chances.
