Five penalties and a sixth kick from the 21-year-old outhalf in the second half landed Ulster a 12-18 victory in Swansea - giving the side a three-game winning streak in this season's RaboDirect PRO 12.
The scoresheet remained blank until the first of two strikes from the Ospreys.
But despite Ulster holding most of the territory in the first half, the Ospreys managed six points thanks to kicks from Dan Biggar - the first coming in the 20th minute.
A second came right on half time to put the home side 6 - 0. Biggar then added another six points to the scoreline in the second half.
But four successful penalties from Paddy Jackson brought the Ulstermen level at the end of the third quarter, before a fifth brought the Ulstermen ahead.
A sixth kick from Jackson ended home side's chance of a victory.
Heading into tonight's game, the loss of British and Irish Lions star Tommy Bowe for the clash had been eased by Ulster being able to recall fit-again Ireland international wing Andrew Trimble for Friday's date with Ospreys in Swansea.
Tonight's opponents weren't short of quality - with the Ospreys' star-studded pack including five of the 2013 Lions.
Ospreys had been one of only two unbeaten teams this season - but Ulster's win in Wales put an end to that.
