Second-seeded Jessica Pegula had a 4-6, 6-2, 6-3 win over fellow American Bernarda Pera on Wednesday to advance to the quarterfinals of the Adelaide International. Pera earned a spot in the main draw as a so-called lucky loser from qualifying and then upset former No. 2-ranked Paula Badosa in the opening round. Pegula went 1-for-10 on break points in the first set as Pera’s powerful left-handed game led to the unseeded player’s early advantage. But Pegula found her rhythm in the second set, where she hit 11 winners to six unforced errors.
