Gilroy, 26, crossed the whitewash three times in Ulster Rugby’s impressive 59-10 defeat of the Southern Kings at Kingspan Stadium on Friday night.
The winger – who beat nine defenders in the game – earned 30 fantasy points in the process and is now the competition’s second-top try scorer with eight in just six outings.
Ulster are struggling for consistency this year but have a good platform for the run-in, eight points behind joint leaders Leinster Rugby and Scarlets in Conference B.
Robin Copeland’s all-action display for Munster Rugby in their bonus-point defeat of Zebre was rewarded with a haul of 18 fantasy points.
The 30-year-old is a sensible investment for Six Nations gameweeks and has already bettered last year’s fantasy performance of 32 points.
The No.8 picked up points for a 50-metre run, 15 tackles and a try in Munster’s win over the Italians, keeping them second in Conference A.
Colossal Kiwi flanker Nick Williams chipped in with 18 points for Fantasy Rugby head coaches with a Man of the Match display in Cardiff Blues’ 25-20 win over Toyota Cheetahs.
Williams has only made two full appearances in the Guinness PRO14 this season but signed a new contract with the Blues last month.
He snatched a vital third try in the 53rd minute and also supplied an assist in his best performance of the campaign so far at No.8.
