The final, presented by the Professional Bowlers Association (PBA), wrapped up the 15 event, global series tour and featured a new trial scoring system labelled current frame scoring

The finals aired on ESPN and featured the perfect 300 game from Barrett against America's Mike Fagan, who scored 256 in the title match.

The semi-finals saw a close game between Fagan and Australia’s Jason Belmonte with Fagan moving on with a win of 265 over Belmonte’s 256.

In the women’s event, McEwan took on seasoned veteran and number one in ranking points, Kelly Kulick to win the title with a nail biting finish where McEwan took 256 to Kulick’s 243.

America's Liz Johnson was beaten by McEwan in the semi-finals with McEwan triumphing on a final score of 256 to Johnson’s 233.

Current frame scoring maintains the traditional 10-frame scoring format but awards 30 pins for a strike, 10 pins for a spare plus the pinfall of the first shot in the frame and actual pinfall after two shots in an open frame.

The maximum score is still 300 and this figure is based on the player receiving 10 consecutive strikes with no bonus pins being awarded in the 10th frame.

For bowling the first-ever perfect game under the experimental format, the PBA awarded Barrett its traditional $10,000 (£7,000/€9,000) bonus for the 300 game.

Barrett said he liked the idea behind the new scoring system, which is part of the sport's on-going campaign to get onto the Olympic programme.

“I think the idea behind it is great, trying to get us into the Olympics,” he told the PBA website. 

“If it helps get [bowling] more onto the international stage, the more people who understand it, the better.

"The reasons behind [the modified scoring system] are all very good reasons.”
