American Jessica Pegula reached her second straight US Open semi-final with a clinical 6-3 6-3 win over twice Grand Slam champion Barbora Krejcikova on Tuesday, in the first match of the day on Arthur Ashe Stadium.
Fourth-ranked Pegula had a dreadful run-up to the year's final major but has flipped the script in New York, where she has yet to drop a set and fired off 17 winners to beat the unseeded Czech.
Krejcikova recovered from injuries earlier this year and saved eight match points in a fourth-round thriller to reach the final eight but ran out of gas against the 2024 runner-up.
Pegula will next play the winner of the match later on Tuesday between the defending champion and world number one Aryna Sabalenka and unseeded Czech Marketa Vondrousova.
