St Helens winger Regan Grace clocked the highest speeds of any player in Super League last season.
The Welshman recorded speeds of up to 36.07 km/h, slightly ahead of Wigan’s Liam Marshall and Hull KR’s Matt Parcell, who both achieved an impressive 35.96 km/h.
Grace also enjoyed a successful try-scoring campaign, bagging 20 scores in Super League and two more in the Challenge Cup.
The 23-year-old finished the year with a League Leaders Shield and Grand Final winners medal to his name, but failed to secure a spot in Great Britain’s post-season touring squad.
Meanwhile, Ratu Naulago clocked 35.89 km/h in his first season in professional rugby, while Warrington duo Daryl Clark and Jake Mamo rounded off the top six.
The figures were released by Super League ahead of the new campaign, which gets underway next month.
