A day after their exit from the tournament was confirmed, captain and flyhalf Lionel Cronjé kicked a penalty after the hooter had gone to bag the one-point win against the struggling Pretoria outfit.
The Kings, however, were well on top at the halftime break, with three first-half tries giving them a 22-10 advantage.
Perhaps they relaxed and thought the game was over as a contest, as they were much more urgent than the hosts in the opening 40 minutes.
The Bulls, though, bounced back in the second half when wing Duncan Matthews touched down to make it 22-17.
Two penalties by Tian Schoeman put the Bulls in front at 23-22 after 67 minutes, and it looked like the men from the coast had run out of puff following their travels in South America last week.
But, as he’s done all season, their skipper stepped up.
Cronjé booted over a drop goal a minute later and his second penalty soon after that, and it was 28-23 to the Kings.
The Bulls, though, scored the try of the match with Jan Serfontein again prominent, and it was replacement hooker Jaco Visagie who burst through with three minutes to go.
The conversion made it 30-28 for the Bulls.
The Kings then won a scrum penalty inside the Bulls’ 22, and Cronjé coolly slotted an angled effort for an epic win.
