Just as quickly as play at Wimbledon began, there was an upset and an injury.

Monica Puig, a Puerto Rican player who trains in Miami and is ranked 65th in the world, stunned Sara Errani, the fifth seed, 6-3 6-2 on Court 18.

Errani was a French Open semifinalist just a few weeks ago and was a French Open finalist last year. Although she saved six match points, she couldn’t stop Puig, who will play Silvia Soler-Espinosa next. Puig had never played a senior Grand Slam tournament before the French Open this year. This is her first grass-court tournament as a pro.

Victoria Azarenka, the No. 2 seed, needed an injury timeout after slipping on the wet grass in her match against Maria Joao Koehler. Azarenka’s right knee was wrapped and she continued her match. Although she beat Koehler 6-1, 6-02, she was limping noticeably and favoring her leg.

“It was such a shock to me,” Azarenka said in a BBC interview. “I slipped and felt my body collapse. … I couldn’t believe what was going on. I don’t know what happened out there, but it was just trying to stay in the moment and give the best I can. It was very emotional.”
