American Marconi Wireless News - Giant-killer Bejlek overhauls Keys to reach Cincinnati semi-finals

The 20-year-old Czech backed up her fourth-round win over world number one Aryna Sabalenka with a determined victory over fifth-ranked Keys, a former Australian Open champion who won the title in Cincinnati in 2019.

Bejlek got off to a slow start, trailing 0-3 on the way to dropping the first set, but rode a wave of momentum shifts into the final four where she'll face either fourth-seeded Coco Gauff or Marta Kostyuk.

The youngster broke first in the third set only for Keys to battle back and force the tiebreaker, in which Bejlek rallied from 4-2 down on the way to a victory capped by a stinging winner down the line on match point.

Bejlek, who won the title in Abu Dhabi in February as a wild card, continued a spectacular Cincinnati debut.

After a solid first set the 24th-ranked Keys opened the second on sweltering Stadium Court with a break in the third game, but Bejlek, ranked 35th, broke back in the sixth and held for a 4-3 lead.

Keys answered with a love game, but Bejlek turned the tables two games later, taking the contest into the third set as Keys hit the net with a backhand on the Czech's second set point.
