Federer to face Chung in Australian Open semis

MELBOURNE, Australia — Roger Federer got cranky at the chair umpire for a technology flaw in his Australian Open quarterfinal match, using the rare emotional outburst as motivation.

It helped. The 36-yearold Federer, now the oldest semifinalist in Melbourne in 41 years, beat long-time rival Tomas Berdych 7-6 (1), 6-3, 6-4 Wednesday and will next face a challenge from the next generation.

That will be against 21-year-old Hyeon Chung, the first South Korean to reach a Grand Slam semifinal and the youngest to reach the last four at a major since 2010.

Federer’s victory extended his winning streak to 14 in Australian Open quarterfinals and to nine in a personal rivalry with Berdych that dates back to 2004. The 19-time major champion leads that headto-head contest 20-6, including all five meetings at Melbourne Park.

Federer had to overcome a shaky start, dropping his opening service game and uncharacteristically questioning chair umpire Fergus Murphy because of a technological fault. With Berdych serving for the first set in the ninth game, Federer had challenged a line call.

After a lengthy delay, Murphy called the control room and confirmed the replay graphic couldn’t be displayed on the stadium screen, and also that the original decision

stood. When he added that Federer had no challenges remaining for the set, Federer approached the chair and the crowd cheers intensified.

with this? You’re OK with it?”

Seven points later, he eventually broke Berdych to get back on serve, and then won the tiebreaker. The match was as good as over.

“I had to get a bit lucky. A bit angry. A bit frustrated maybe at the umpire,” Federer said. “Anyway, glad to get out of that first set. It was key to the match.”

Federer later said he just wanted an explanation from the chair, and agreed that blowing off steam helped his cause.

“I was under pressure. It was definitely very close, the turning point,” he said. “I played a great breaker. But coming back from 5-2 in the first set, it was clearly big tonight.”

Chung beat 97thranked Tennys Sandgren 6-4, 7-6 (5), 6-3 in the afternoon match.

He hadn’t let up in upset wins over No. 4 Alexander Zverev or six-time Australian Open champion Novak Djokovic, but he let his guard down in the last game against Sandgren and needed six match points to finish it off.
