Swedish national team member Tobias Karlsson put on a show in the second squad on Saturday, the 16th overall, en route to overtake the third position in the qualifying the Norwegian Open in Oslo.

The defending champion, who admits he is primarily left-handed but prefers to bowl with the right hand, started his six-game series with 234 and 186 before he rolled the 7th perfect game of the tournament and one of many in his career.

"I don't know exactly, how many 300 games I have bowled," Karlsson had to admit, "but definitely more than 20."

He added 237 and 228 in games four and five before he got another chance for 300 in the final game.

After 11 strikes the final shot (pictured) went too high and left the 3-6 combination standing to finish with 298 and a 1483 pinfall total, an average of 247.16. Click on the image to enlarge it.

With the final two squads to go, Karlsson's compatriot Robert Andersson (left) held on to the lead with 1497 or an average of 249.50. Xavier Lotthe, France, is second with 1487. Rounding out the top 5 are Norwegians Mads Sandbækken and Ingunn Øien, with 1470 and 1466, respectively.

Øien (right), who won the European Champions Cup last month, is the best of six women among the top 40.

The others are 7th Ghislaine van der Tol, Netherlands, 1455; 17th Nina Flack, Sweden, 1420; 20th Patcharin Torgersen, Norway, 1410; 31st Ann Louise Haugen (left), Norway, 1378 and 33rd Priscilla Maaswinkel, Netherlands, 1373.

The Norwegian Open 2007 is the 17th stop of the 2007 European Bowling Tour and one of the Tour's Challenger events. The tournament offers total prize money of 351.000 Norwegian Kronor, approximately 65,250 U.S. Dollar or 45.715 Euro. The winner will receive the 60.000 NOK top prize ($11,150/€7.815).

Qualifying concludes on Saturday, October 6 with Squads 17 and 18 scheduled for 4.00 and 8 p.m. local time (GMT +1). The ultimate one-game Desperado Squad is scheduled for 11.30 p.m.

The top 40 players from the qualifying (cut is now 1349) will automatically advance to the finals. They will be joined by the top four players from the first weekend (combined standings of squads 1-4) not among the top 40 and the top 4 from the Desperado Squad.

The top 12 earn two byes (cut: 1440), while players ranked 13-24 (cut: 1402) will bypass the first round. The first three rounds of the final consist of four games from scratch with half of the field advancing to the next round.

Once the field is cut to the top 12, players bowl two games from scratch to cut to the top 8, then the top four, who advance to the semi-finals (No. 1 vs. No. 4, No. 2 vs. No. 3). The winners of these one-game matches will bowl for the title and the 60.000 NOK top prize.

Bowlingdigital will cover the event live from Oslo commencing Friday, October 5 all the way through to the finals on Sunday, October 7.
