London, July 1 -- American third seed Jessica Pegula said her first-round Wimbledon exit was her "worst result of the year" as she became the highest seed to fall at the tournament so far.

Pegula was below par in a 6-2 6-3 defeat by Italy's Elisabetta Cocciaretto, ranked 113 places below her at 116 in the world.

The 31-year-old had heavy strapping on her right knee but said that did not bother her as she was dismantled in just 58 minutes on court two.

"This is definitely probably the worst result I've had all year," she said.

"I've been winning lots of matches. It's just all about it having to come together for two weeks. Sometimes it doesn't quite all align when you need it to."
