Wakefield Wildcats head coach James Webster praised his side's guts and determination after they sprung a surprise 36-28 defeat on reigning champions Wigan Warriors.
Australian Webster became the youngest head coach in the Super League when he took over at the start of the month, aged 34, following the departure of Richard Agar but has since overseen two victories.
Wildcats had led 24-18 at half-time with captain Danny Kirmond among their four try scorers before Wigan hit back with Liam Farrell scoring two of their five tries.
But with Danny Washbrook and Reece Lyne running in the decisive late scores, the hosts moved 10 points clear of the drop zone.
"It was an exciting game. I thought the boys played really tough and gutsed it out," said Webster.
"Wigan came at us for the full 80 minutes. I thought it was a decent game of rugby if you're a neutral, and you will have enjoyed it.
"But as a Wigan or a Wakefield supporter there were a couple of moments where it was heart-in-your-mouth sort of stuff.
"I'm under no illusions that we got them at a good time. The first day I spoke to my staff preparing for Wigan, I said we had a massive advantage."
To compound the defeat, Wigan dropped down to third after wins for new leaders St Helens over Castleford Tigers and Leeds Rhinos over Widnes Vikings.
Veteran captain Paul Wellens grabbed a brace for the Saints, as did Mark Percival, as they ran in seven tries in a comfortable 38-16 win.
While it was a closer affair at Widnes as Rhinos made up a six-point half-time deficit by running in five second-half tries to win 38-28.
London Broncos' search for their first league win of the season continues after they lost out 38-22 at Huddersfield Giants on Saturday.
James Cunningham crossed in the first half but it was outnumbered by four from Giants through Scott Grix, Brett Ferres, Jermaine McGillvary and Joe Wardle.
McGillvary and Wardle then added their second tries after the break with Broncos head coach Joe Grima was left to rue his side's slow start.
"You can't give any team a 20-point start, let alone a side like Huddersfield Giants," he said.
"There's got to be a wooden spoonist in every competition. We'll be doing our best to avoid it."
Saturday also saw Catalan Dragons defeat Hull FC 20-16 but only after holding off a strong fightback from Lee Radford's men.
And on Friday, Hull KR were in ungenerous mood against struggling Bradford Bulls, inflicting a 44-18 defeat.
The Bulls, who are now nine points from safety and sacked coach Francis Cummins last week, failed to recover from conceding three tries in seven minutes either side of the break.
"We knew there would be a positive reaction from Bradford after what happened this week and they started well," said Hull KR coach Craig Sandercock.
"They put us under a lot of pressure but defensively we showed a lot of resolve on our own line.
"We were under the pump but defensively we were much improved."
