SOUTH WILLIAMSPORT, Pa. — Jungtaek Ru was 3 for 4 with four RBIs and three Seoul pitchers combined to strike out 15 as South Korea beat Canada 10-0 in five innings on Monday night in the Little League World Series.

Starter Youbin Choi and reliever Wontae Cho retired the first 14 batters — all on strikeouts — and Canada didn't get its first hit until Stefano Dal Sasso's single in the fifth with two outs.

South Korea's offence broke it open with four runs in the fourth and again in fifth.

Cho had a RBI triple and Ru hit a three-run homer to right field to make it 6-0. In the fifth, Moosung Kim sent a ball over the centre-field wall and Cho homered to make it 8-0.

Seum Kwon had a RBI single to make it 9-0 and he scored from first base on Minho Choi's single to the wall.

South Korea will play Panama on Wednesday night in the international semifinals. Canada, a club from Vancouver, British Columbia, faces Mexico in an elimination game on Tuesday.
