Vietnam's top junior tennis player Ly Hoang Nam has been knocked out of the Copa del Cafe in Costa Rica after losing to Jorge Brian Panta Herreros of Peru in the quarter-finals.

Unseeded Nam was defeated by the No 4 seed and world junior No 31 Herreros 3-6, 3-6.

The 15-year-old has already surprised many by beating three top players to reach the latter stages of the tournament.

Nam, the world junior No 162, will next move to Venezuela to compete in the Copa Gatorade from January 7-13.-VNA
