"Chung was really starting to get his range at 6-5 in the first set and it was hard then", said Federer. "Hopefully I can do one more and beat my best streak on Saturday".
"I don't care what's happening on court, I just try to execute my game", Williams said. "I have played him once before and I did very well against him so something similar would be nice".
And in the second Federer pulled away to improve his spotless record in 2018 to 16-0, his best start to any year since 2006 when he went 16-0 at age 24.
He clinched the victory on the second match point when he blasted his 12th and final ace of the contest.
Federer will next meet Croatia's Borna Coric, who reached his maiden ATP Masters 1,000 semifinal by beating Kevin Anderson of South Africa 2-6, 6-4, 7-6 (3). It was a golden chance for Chung to create a situation when the first set and early momentum was completely up for grabs, but the dominant Federer once again elevated his play in the important moments. "He has all the confidence in the world right now so it is going to be tough", the 20-time Grand Slam victor added. I don't really know when the tennis things are going to click.
The bespectacled Chung, appearing in his fifth quarter-final in six tournaments this year, dropped to 15-6 this season. Chung is expected to rise to a career high of No. 23 on Monday.
"I'm really honored to be number one Asian", Chung said.

Even though he couldn't match the effort in the second set, it was a better match than he gave the 20-time major victor last time.
Earlier this year he defended his title at the Australian Open, picking up his 20th Grand Slam win. But it is a totally different year, and so many years after, he said. They are one of the best players in the world, winning Grand Slams. But I'm enjoying a lot.
