Derek Sheils became the first double winner of the Adelaide Masters Series at Mondello Park over the weekend.
The Dublin rider finished third in Saturday’s opening race to secure the points he needed to lift the championship.
The race was won by Waterford rider Brian McCormack, who came through to pass Sheils and Gerard Kinghan.
With the title safely secured, Sheils upped the ante on Sunday to win both Superbike races, underlining his superiority at the Co Kildare circuit this season, although he was made to work hard in the final race by a determined McCormack.
Sheils had been unbeaten at Mondello Park in the 2015 Masters Series until Saturday’s opening race and proved a cut above his rivals again once the title was secured.
Second place in the championship standings went to Randalstown rider Kinghan with Ryan Rainey finished third overall, even though he was ruled out of the weekend’s final round due to mechanical problems with his Yamaha R1.
Bangor rider English also put the title beyond reach on Saturday with a win in the opening Supersport race over Jason Lynn, who had led the race before encountering slower riders and losing several places.
On Sunday, newly crowned champion English didn’t have the swansong he had been hoping for as he crashed out of both races.
Conor Parkhill and Robert Kennedy finished second and third respectively in the table despite missing the final round.
