Gomez proved to be the key man for sixth seeds Chile as he defeated Daniel Gonzalez 4-11, 11-9, 13-11, 11-7 and Brian Afanador 11-13, 20-18, 11-9, 11-7 to set up a thrilling finale.

Juan Lamadrid then held his nerve to beat Gonzalez 11-5, 7-11, 11-8, 11-5 to secure a semi-final meeting with the United States.

Afanador had defeated Lamadrid 11-7, 11-5, 8-11, 11-6 and Angel Naranjo saw off Felipe Olivares 11-8, 11-1, 11-2, but fourth seeds Puerto Rico’s title hopes were extinguished by Chile.

Brazil, who were given a bye into the semi-finals along with the US, will take on Argentina who downed Canada with a 3-0 triumph.

Horacio Cifuentes and Gaston Alto both claimed straight-games wins, beating Matteo Martin 11-6, 11-7, 11-2 and Edward Ly 11-7, 11-7, 11-7 respectively before Santiago Lorenzo came from behind to beat Chen Hongtao 11-4, 13-15, 10-12, 11-7, 11-5.

While Puerto Rico’s men’s team suffered a narrow defeat, the nation’s women’s side crashed to a convincing 3-0 loss in the quarter-finals.

Adriana Díaz, who won the women’s singles title earlier this week, notably did not feature in the Puerto Rican line-up.

Brazil made light work of their opponents as they failed to drop a single game with Bruna Takahashi thumping Daniely Rios 11-5, 11-6, 11-9, Carolina Kumahara beating Melanie Dias 11-1, 11-8, 11-6 and Jessica Yamada seeing off Fabiola Diaz 14-12, 14-12, 11-7.

The US will meet Brazil in the semi-finals of the women’s team competition, while Canada will face Chile after overcoming Argentina 3-1.

Zhang Mo registered two wins for Canada, defeating Camila Arguelles 11-8, 7-11, 11-8, 11-6 and Ana Codina 24-22, 11-4, 11-6.

Tong May Hui added further success by overcoming Codina 11-9, 11-7, 12-10.

Argentina’s solitary triumph came courtesy of Candela Molero who beat Ivy Liao 11-7, 11-8, 11-6.

Competition is due to conclude tomorrow with the semi-finals and finals of the men’s and women’s team events.
