Lee Smith's late drop-goal proved the difference on Monday at the KC Stadium as Wakefield Trinity Wildcats edged a topsy-turvy encounter with Hull FC 27-26.
Kirk Yeaman's late try for the hosts looked to have salvaged a draw, although Danny Tickle missed the conversion, but with only a minute remaining it was former England international Smith who kept his nerve to slot the crucial one pointer.
Ben Crooks had earlier notched a second consecutive Super League hat-trick for Hull but once again found himself on the losing side after last weekend's defeat against Castleford Tigers.
It was the Wildcats, who led 16-10 at the break thanks to scores from Peter Fox, Paul Sykes and Oliver Wilkes, who held their nerve at the end behind some superb tactical kicking from former Parramatta Eel Tim Smith who laid on tries for first Lee Smith and then Fox.
The defeat means Hull missed out on the chance to move up to fifth in the Super League table despite Crooks' treble and scores from Tom Lineham and Yeaman.
On Sunday Warrington Wolves closed the gap on Super League leaders Wigan Warriors to only two points with a 26-12 victory at Bradford Bulls.
Wolves ran in five tries in the first-half from Ben Currie, Lee Briers, Michael Monaghan, Trent Waterhouse and Ryan Atkins to lead 20-0 at the break.
Replacement Chev Walker and James Donaldson responded for the Bulls after the interval but it was too little too late.
Defending champions Leeds Rhinos edged a high-scoring encounter at Widnes Vikings, Zak Hardaker scoring a try and kicking 12 points in a 52-36 victory.
Kevin Brown scored a hat-trick for the Vikings but Joel Moon ran in two of the Rhinos' ten tries on the night in a comfortable victory.
On Saturday Lee Gaskell scored a first-half hat-trick as Salford climbed off the bottom of the Super League and above hosts London Broncos with a 44-30 win.
Former St George Illawarra Dragon Jamie Soward, who only arrived from Australia on Saturday morning, scored a try and kicked 10 points for Broncos but the Reds ran in eight tries in all to secure their first away win of the season.
On Friday table toppers Wigan lost their second game in a row in the league, falling to a shock 18-4 defeat against Castleford.
First-half tries by Kirk Dixon and Grant Millington earned the Tigers a 12-0 interval lead and James Clare's try then extended that lead before Josh Charnley pulled a try back.
But that was as good as it got for the Warriors who were without Sam Tomkins, Lee Mossop and skipper Sean O'Loughlin through injury.
That left the door open for second-placed Huddersfield Giants and they took full advantage, closing the gap to only one-point at the top with a 60-16 win over Catalan Dragons.
Brett Ferres led the way with his first hat-trick while Jermaine McGillvary also went over three times for the hosts as Danny Brough racked up a 20-point individual haul.
And finally Michael Dobson inspired Hull KR to a fourth straight Super League victory at the expense of St Helens.
The Australian half-back, who revealed this week that he will join Newcastle Knights next season, kicked six goals and proved a major threat all night in his side's 24-12 win.
