A late penalty from Kurtley Beale saw the Rebels claim a 32-31 victory over the Force on Sunday in a result that lifts them to third in their conference.
In a game that was 26-15 at the break in favour of the away side, the Force had fought their way back and were just three minutes away from victory.
But up stepped fly-half Beale from wide on the left to wipe off what had looked like being the winning penalty from Ben Seymour just moments before.
Beale was once again superb in the number ten jersey as the Rebels look a different team with him there instead of the departed Danny Cipriani.
His long, flat passes caused the Force ample problems early on while he also threw in line breaks for good measure in a performance that will have impressed Wallaby boss Robbie Deans.
The Rebels scored four tries in the first-half, with lock forward Cadeyrn Neville grabbing a brace, while captain Gareth Delve and wing Cooper Vuna also found their way to the whitewash.
However, the out-of-form Force responded from the hammering they took at the Sharks last weekend with tries from Fijian winger Napolioni Nalaga, number eight Ben McCalman and replacement Alfi Mafi to set up a grandstand finish.
When Force scrum-half Brett Sheehan kicked a long-range penalty with his last touch from the halfway line to make it 26-25 on the hour, it was then a case of a penalty shoot-out as Beale and Seymour traded blows before the star Wallaby landed the sucker punch.
