Hector Soto scored 29 points yesterday as Puerto Rico downed the US in four sets at the volleyball Men's World Cup for their first win over the Americans in 30 years.
Jose Rivera added 14 points to help Puerto Rico to a 25-21, 20-25, 25-17, 25-22 win over the US and a 2-0 record in the 12-nation tournament.
The US, who upset Brazil on Sunday, dropped to 1-1 .
"They had a great win yesterday and so maybe had a little bit more pressure," said Puerto Rico coach Carlos Cardona. "We had less pressure, didn't feel very nervous and were in a good situation. Today is a historical win for Puerto Rico."
William Priddy had a team-high 16 points for the US.
"It's obviously disappointing that we didn't play with the same sense of urgency as yesterday," US coach Hugh McCutheon said. "You think we would have learned from previous tournaments that you can't approach games without total intensity. Hopefully we can play better tomorrow [today]."
The last time Puerto Rico beat the US was at the 1977 Norceca Championships.
