Marcelo Martinez struck out 12 as Reynosa of Mexico held off a late rally to stay undefeated at the Little League World Series with a 3-2 victory over Taoyuan of Taiwan Tuesday. Mexico will now face Chiba City of Japan in an international semifinal, while Taiwan will meet Willemstad of Curacao in the other semifinal . Martinez didn't allow a hit but was lifted with two outs in the fifth after reaching his 85-pitch limit. Taiwan broke up the no-hitter when Wen Hua Sung homered off reliever Jorge Maldonado to open the bottom of the sixth. Taiwan got another run on two outfield errors on the same play, but reliever Raul Rojas struck out the final Taiwan hitter. Mexico hit three solo homers. Otherwise, Tuesday served as an anticlimactic end to pool play, as all the teams playing had either already been eliminated, or already advanced. Dhahran of Saudi Arabia scored five times on just one hit during a sloppy first inning by Maracaibo of Venezuela in a 5-3 win. Reliever John Sheppard held Venezuela hitless for the last three innings in the first win for Saudi Arabia, which was comprised mainly of children of US citizens. Trailing 1-0, Cameron Durley had Saudi Arabia's sole hit with a two-run single in the bottom of the first. The team scored three more times on an error, a hit batter and a walk. Venezuela also took advantage of miscues, with Oberto Munoz scoring on a three-base error in the second and a wild pitch, and Mikey Edie scoring on an error in the third. Vancouver of British Columbia gave up an eight-run lead, then rallied with four runs in the sixth for a wild 14-13 win over Ramstein Air Force Base of Germany. In the US pool, Austin Batchelor homered and scored three runs, and Peabody of Massachusetts, used a nine-run third inning to pull away from Russellville of Kentucky 12
