Puerto Rico played in its first World Cup in 2018 and was winless in three games in that tournament. The country was also winless in the Tokyo Olympics last summer.
“It’s a great win for us. We didn’t win a game in the last world tournament,” Puerto Rico coach Jerry Batista said. “We are very excited and happy about it.”
The win comes at a difficult time for Puerto Rico as the island tries to recover from the destruction caused by Hurricane Fiona earlier this week.
“I know that you are going through a tough time. … We’ve been through this before, so I know everyone in the community will lean on each other and help each other out. Stay safe,” guard Jennifer O’Neill said.
