Castleford Tigers were at their brilliant best as they hammered St Helens 53-10 to book their place in the last eight of the Ladbrokes Challenge Cup.
Winger Greg Eden, Betfred Super League's leading tryscorer this season, led the spree with a 19-minute hat-trick early in the second half to put the gloss on another breath-taking display from classy Cas in a one-sided sixth-round tie.
Jake Webster, fresh from signing a contract extension, and Greg Minikin each crossed twice while Michael Shenton, Paul McShane and Nathan Massey touched down and Luke Gale booted 13 points.
St Helens are one of three teams to defeat the Super League leaders this year but that was on home soil and they were unfortunate to come up against a rampant side who have not failed to score under 40 points at the Mend-a-Hose Jungle so far.
The Tigers were simply ruthless against a Saints side for whom it seems the arrival of new coach Justin Holbrook, expected to arrive from Australia in time for Magic Weekend, cannot come soon enough.
St Helens caretaker coach Jamahl Lolesi said: "Justin can't come quick enough. He should be here this week, which will be great. We probably need someone to come in and try something different to get the group going.
"Unfortunately we're in a bit of a hole at the moment. It's a little bit worrying. We've got some issues we need to sort out. We've a group of young men who will need to stand up and start doing better for the club.
"On behalf of the coaching staff, I'd apologise to the fans who paid their money to watch that, it must have been hard for them. Obviously Cas are a really good side when you let them play on top of you which is what we did. They are like the Harlem Globetrotters."

Castleford coach Daryl Powell said: "I thought we were very good. There was a period when we had to dig deep defensively but we did that and then blew them away.
"Some of our play was exceptional. I'm really pleased with the group and the way they're going about their business."
