Northern Irishman Glenn Irwin had a solid weekend when the British Superbike opened at Oulton Park to take ninth place in the standings.
The Honda rider recorded three top-10s, with sixth place in Saturday’s opening race being his best result.
Synetiq BMW rider Andrew Irwin had a disappointing weekend with two retirements and a 15th place finish.
Yamaha’s Jason O’Halloran completed a treble of victories on the weekend by winning both Superbike races on Sunday.
After finishing sixth in Saturday’s opening race, the Honda Irwin rider reached fourth in the opening stages of Sunday’s opening race before dropping out in ninth.
He also struggled in the third and final race of the weekend. Starting from 10th place, the 31-year-old was sidelined at the third corner but recovered to take 10th place after falling to the back of the pack.
Any disappointment has been put into perspective compared to his brother Andrew, who scored just one point in his debut in Synetiq BMW. The 26-year-old crashed in Saturday’s opener, finished 15th in race two and retired from the last race due to a mechanical problem.
Australian O’Halloran, whose victory in race two came after a final lap on Christian Iddon, leads the championship over the Englishman by 15 points, with BMW’s Peter Hickman 20 points behind in third .
Success in the Support Streak
Northern Irish riders have had mixed results in the support championships around the Chester circuit.
Fermanagh’s Lee Johnston landed a podium in the last corner of the Supersport race. Jack Kennedy of Dublin, who won Saturday’s race, was passed by Bradley Perie on the final lap, with Johnston completing the podium.
Ballynahinch’s Korie McGreevy crashed halfway after running for the lead of the race, which also hosted GP2 machines, aboard a Yamaha Mar-Train Racing, with Eunan McGlinchey 15th, Scott Swann 17th and Rhys Irwin from Donegal 20th.
A 15-second penalty deprived David Allingham of a good result in the British Superstock Championship. The Eglinton runner ran second for most of the race but was ranked 23rd under the checkered flag.
Keith Farmer was eighth, one position ahead of 16-time Isle of Man TT winner Ian Hutchinson. Michael Dunlop came out of points in 17th.
