Ian Lowry scorched to his maiden British Superbikes victory in the first of two races in the second round at Thruxton on Sunday.
As a result, finishing fifth the next time out puts the Padgetts Honda Rider on top of the title standings.
The Ulsterman had been on the pace throughout the weekend and he harassed reigning champion Tommy Hill for much of the first race, never more than half a second down and, as the Swan Yamaha rider struggled for pace complaining of tyre issues, Lowry timed his move at Campbell to perfection.
"That was an absolutely fantastic result for me and the team," said Lowry.
"It worked out so well. I was able to sit there, watch Tommy setting the pace and then when he started to struggle a bit with five laps to go I knew where to make the move on him.
"I had the grip and was able to take him and pull away - it was just awesome coming round and seeing that I had a lead of one second."
Lowry was unable to make it a double, though, finishing fifth in the second race.
Aussie Josh Brookes snatched the victory for Tyco Suzuki in that race with a dramatic last-lap move to deny Hill who had to settle for second best again just ahead of the Rapid Solicitors Kawasaki duo of former two-time title winner Shane Byrne and Stuart Easton.
