It was grand final week for thousands of NRL Fantasy head-to-head leagues with several big guns coming through with the goods when it mattered. Here are this week's Fantasy winners and losers.

Winners

It was a massive week for the wingers, with not one but two star speedsters going past the century mark. Melbourne Storm flyer Suliasi Vunivalu had easily his best Fantasy score ever with a three-try, 14 tackle break 115-point effort in his team's rout of Souths, while Semi Radradra scored four tries to notch 104 points in Parramatta's stunning win over Brisbane.

The ageless Luke Lewis was another surprise success story this week, scoring 85 including a dozen tackle breaks in the Sharks' tight loss to the Roosters, while popular Fantasy buys Paul Vaughan (77) and Cameron Munster (73) both starred in winning efforts.

Jason Taumalolo (72) narrowly edged Cameron Smith (71 in 58 minutes) as the best of the usual captaincy options, while Aaron Woods (71), Jordan Rapana (70), Billy Slater (70), Jake Trbojevic (66), Jack de Belin (62) and Simon Mannering (61) were the best of the other popular Fantasy buys.

Losers

Dylan Edwards' knee injury came at just the wrong time for both the Panthers and Edwards' Fantasy coaches, with the dynamic fullback finishing on just 10 points as Penrith went down to the Dragons.

It was also a quiet week for Manly utility Lewis Brown - owned by exactly 29999 Fantasy coaches – who scored 8, as well as Elliott Whitehead (13), Nick Cotric (13), Jarryd Hayne (14), Curtis Scott (16), Akuila Uate (20) and Latrell Mitchell (20).
