Castleford Tigers came from behind to beat Wakefield Trinity 25-24, securing their 10th Super League win on the spin.
Daryl Powell's men overturned a 16-point deficit to fifth-placed Wakefield at Beaumont Legal Stadium before Luke Gale secured the win with a last-minute drop goal.
Greg Eden scored a sensational 90-metre try and Jake Webster had put the Tigers back on track after David Fifita's late score had looked like stuffing the visitors' comeback.
The League Leader's Shield is now Castleford's to lose after they went 10 points clear of second-place Salford Red Devils and few would bet against them going all the way after adding this gritty display to their many glittering ones in 2017.
Castleford were a million miles away from their free-flowing best throughout the first half, with Wakefield lifted by Ben Jones-Bishop's fine try, having run the length of the field.
Liam Finn added the extras and a penalty soon after, before Eden touched down in spectacular fashion but saw the points wiped out due to an earlier obstruction.
Kyle Wood's try was converted before Finn again scored from the tee to put the hosts 16-0 to the good at the interval.
If Powell had demanded a response from his players at the break, he was given a huge one - Eden setting the tone for a thrilling second half with his 32nd try of the season after switching on the afterburners to leave Wakefield standing.
Castleford were rampant and Wakefield buckled under the pressure, Scott Grix knocking on to open up a chance that Grant Millington finished before Nathan Massey's superb break preceded Mike McMeeken touching down - Gale's conversion putting them ahead for the first time.
Fifita looked to be the hero as he barrelled through three Tigers to touch down, before Gadwin Springer was pinged for holding on and Finn's penalty looked like snapping the Tigers' run.
But Wakefield knocked on from the kick-off and Castleford marched up the field, setting up Webster's score before another furious attack followed Fifita's high hit and set Gale for a simple drop-goal which secured another win for the leaders.
