The England Knights player said it was a “weird” experience going back to double-chasing Warrington and having such an impact in the 40-26 victory.
Riley has amassed 102 tries in 156 Super League games for the Cheshire club, but was dropped after their opening-day defeat to St Helens and has spent most of the year at Belle Vue.
He had managed just two tries in 17 games for Wakefield but, after being allowed to play against Wolves, made a brilliant return as James Webster’s side kept alive their play-off hopes.
“I did bump into Tony afterwards and said sorry for doing what I did,” Riley told The Yorkshire Post.
“But he told me I fully deserved it. It’s fairly unusual playing against your parent club, especially at Warrington in front of their fans, but they were great.
“Like any winger, I just wanted to get a try so to get a hat-trick was brilliant. It was a bit weird but to win was the main thing – that’s one of our best displays this season – and now we’ve another big game at Huddersfield on Sunday to try keep putting on pressure for that eighth spot.”
It remains to be seen where the 26-year-old will play in 2015.
“I’ve still got a year left at Warrington, but I know Wakefield would like to keep me and I’m really enjoying my time here,” he said. “If something did come up, I’d have to mull it over and it is all about playing. I fell out of favour at Warrington this year and there’s no guarantee I’ll be back in next, but we’ll see.”
Castleford Tigers’ Weller Hauraki could miss their Challenge Cup semi-final.
He faces a potential three-game ban after being charged with striking Hull FC’s Jordan Abdull with his knees.
