Although Berdych created a tense score chase against the Swiss legend, that was not enough for him to create a surprise.
The Czech tennis player quickly took a break to take a 3-0 lead in set 1, but was quickly let back by Fedex. The tense situation forced the first set to determine the winner by a tie-break. The defending champion easily won 7-1 in a "shooting" series to go to a 7-6 victory in set 1.
In set 2, the balanced game was maintained until the 7th game. Fedex unexpectedly accelerated with effective attacks to break away in the hill match. Set 2 was quickly decided with a 6-3 victory for the "Express train".
The game in set 3 did not change much. Berdych was still diligent in seeking opportunities to grasp the game, but Federer did not let that happen. With one more break, Fedex dominated the game and defeated Berdych 6-4 in this set.
After 2 hours and 15 minutes of play, Federer beat Berdych 3-0 to advance to the semi-finals, where he will meet young, in-form tennis player Hyeon Chung - who eliminated Djokovic in round 4 and only took 3 sets to beat Tennys Sandgren in the quarter-finals.
The women's singles event is not surprising, as the No. 1 seed - Simona Halep only needed 2 sets with the scores of 6-3 and 6-2 to overcome Karolina Pliskova.
Halep's semi-final opponent will be Angelique Kerber. Before that, the German tennis player only needed 2 sets to easily win the Madison Keys.
