Danny McGuire kicked a drop-goal in golden point extra-time to give relegation-threatened Hull KR a crucial Super League win over Castleford.
Rovers raced into a 12-0 lead with tries from Craig Hall and Adam Quinlan.
However, Castleford hit back to lead 26-14 with just over 20 minutes left through tries from Pete Mata'utia, Jordan Rankin, Greg Minikin and an eight-point James Clare penalty try.
But two Ben Crooks tries levelled the scores before McGuire's winning kick.
Hull KR remain second from bottom of the table after their fourth victory since the appointment of former Leeds and Warrington head coach Tony Smith in June, but they are now two points above bottom side London Broncos with five games to play and are one of four clubs tied on 18 points.
Castleford slip to seventh after their second golden-point away defeat of the season and Salford's 58-28 thrashing of the Broncos.
Rovers, who gave debuts to new signings Dean Hadley and Jez Litten, led 12-0 and 14-6 but went in behind at the break after conceding an eight-point penalty try when referee Chris Kendall ruled that Tigers wing Clare was fouled in the act of scoring.
Castleford looked comfortable after Minikin capitalised on Rovers turning the ball over 15m from the Tigers line to race away for an opportunistic score.
But two tries in four minutes from Crooks pulled the home side back into the contest before both sides missed a flurry of drop-goal attempts to win the game in normal time.
Rovers had first use of the ball in extra-time and Leeds legend McGuire, who will retire at the end of the season, set up field possession with a 40-20 kick before slotting over the winning drop-goal.
'McGuire like Steve Smith' - post-match reaction
Hull KR coach Tony Smith: "Danny came up with a couple of big plays.
"He's a bit like Steve Smith in that champions shine every now and then. Top-class sportsmen step up in those moments when the rest of us struggle in those pressured situations.
"To come up with a 40-20 and then the field goal straight away was smart play."
Castleford coach Daryl Powell: "How do we not win that game. It's crazy. I thought they were pretty smart in extra-time but we should have won it in normal time.
"We roll from the sublime to the ridiculous and that was ridiculous today, to concede 13 points without reply, we're a frustrating team at the moment.
"There was a lack of composure and nous at the end from different players."
