No. 1 seed for the trios final - Korea: L-R Kim Jinsun, Baek Seungja and Son Hyerin.

Baek Seungja, Kim Jinsun and Son Hyerin of Korea posted scores of 746, 591 and 700 on the long pattern (43 ft. Tokyo) to secure the No. 1 seed for the medal round of the trios event at the Women's World Championships in Abu Dhabi.

The Koreans, who led the 46 trios after the first block on short oil (36 ft. Los Angeles), added 2037 to finish atop the leader board with 4116 total and an average of 228.67. Seungja paced the team with 1384 and was followed by Hyerin with 1375 and Jinsun with 1357.

As the No. 1 seed, the Koreans have the advantage to determine the pattern in the semi-finals which will start on Wednesday at 11 a.m. Gulf Standard Time (GST). They followed in the footprints of their team mates Jeon Eunhee and Hwang Yeonju, who earned the No. 1 and 2 seed for the Singles finals, which will start at 9 a.m.

The Koreans will take on Liz Johnson, Shannon Pluhowsky and Kelly Kulick (pictured left, l-r) from the United States at Khalifa International Bowling Center in Abu Dhabi, United Arab Emirates. The Americans, who led squad 1 with 4039 and an average of 224.39, had to wait until the last three frames of squad 2 to make sure they would be the No. 4 seed.

Heading in the last game, New Hui Fen, Cherie Tan and Shayna Ng (left) of Singapore had narrowed the gap to the Koreans to just 12 pins but had to settle for second place with 4080 (226.67) behind a 676 last game.

Tan and Ng will bowl in both finals on Wednesday as they are the No. 3 and 4 seeds in Singles. The Singaporeans will take on England in the semis. Lisa John, Danni Hopcroft and Jo Allsebrook (right, l-r) had the field-best 2079 on the long to tie Korea for the highest series of the event, just 30 pins shy of the championship record (2109) set by Japan in 2011.

The English women had games of 676, 723 and 680 to leap from 10th to third place and to overtake USA by 17 pins with 4056 (225.33). The second trio from Singapore (left), which finished just five pins behind USA in squad 1, fell out of the top 4 to fifth place with 4034.

Joline Persson Planefors, Jenny Wegner and Nina Flack (right, r-l) of Sweden had a chance to steal the fourth and last place for the medal round but a big split in the 8th frame by Persson Planefors proved to be their undoing. The Swedish trios finished in sixth and seventh place with 3998 and 3987, respectively.

With 12 of 24 games in the books, Shayna Ng took a four-pin lead in All-Events (combined scores in Singles, Doubles, Trios and Teams) with 2781 and an average of 231.75. Singles leader Jeon Eunhee slipped to second place with 2777, just one pin ahead of Cherie Tan with 2776. Liz Johnson is further six pins behind in fourth place with 2770.

The top 4 in singles and trios will return on Wednesday for the medal rounds starting with the singles' semi-finals (No. 1 vs. No. 4 and No. 2 vs. No. 3) at 9 a.m. followed by the finals. The trios' semi-finals will start at 11 a.m. followed by the finals. All times are Gulf Standard Time (GST).
