American Ann Li: Last year’s finalist Jessica Pegula stormed into the quarter-finals of the U.S. Open with a commanding 6-1, 6-2 victory over fellow American Ann Li on Sunday, wrapping up the fourth-round clash in under an hour with a ruthless and clinical display on Arthur Ashe Stadium.

Despite entering the tournament on the back of a shaky hardcourt swing - having made early exits in Washington, Montreal and Cincinnati - Pegula has found her rhythm in New York. The world number four is yet to drop a set at this year’s U.S. Open and looked in complete control throughout her match against Li, striking 12 winners and dictating play from the baseline with powerful, precise groundstrokes.

“I felt really comfortable moving today,” Pegula said after the win. “I felt like today I started off really well and I just wanted to keep executing that.”
