[CLUB WORLD CUP] Jose Francisco Torres started and fellow U.S. World Cup midfielder Herculez Gomez came off the bench for Mexico's Pachuca in its 1-0 loss to TP Mazembe of the Democratic Republic of Congo.
Mazembe went ahead in the 21st minute on a goal by Mbenza Bedi and held off Pachuca despite finishing with 10 players after the ejection of Zambian Stoppila Sunzu with nine minutes to play.
Pachuca's best chance came two minutes before Bedi's goal when Alejandro Manso's shot hit the inside of the post and crossed the front of the goal line before being cleared away.
Colombian Mauricio Molina scored the first goal and set up two others to lead South Korea's Seongnam Ilhwa Chunma to a 4-1 win over Al-Wahda of the host United Arab Emirates in Saturday's only game.
Sasa Ognenovski, Choi Sung Kuk and Cho Dong Geon also scored.
The semifinal pairings: Inter Milan of Italy vs. TP Mazembe and Internacional of Brazil vs. Seongnam Ilhwa.
Pachuca and Al-Wahda move into the fifth-place game.
