Zverev, the top seed at the Acapulco Open, went down 6-3 6-4 to the 19-year-old American on Wednesday.

Tien, who claimed a big win over Daniil Medvedev en route to reaching the fourth round at the Australian Open in January, came from 1-4 down to win the second set – and the match – by reeling off five straight games.

"I just went out there and tried to control my side of the court," said Tien, who will face Tomas Machac in the last eight.

"Obviously, I knew it was going to be a tough match. To come through feels great.

Dhanujakumari is a member of ‘Harita Karma Sena,’ the sanitation program run by the state under the local self-government. She is not a writer who had a room of her own. She lived in many houses in many places—even in an orphanage, as her parents could not manage the family in abject poverty. Despite being gripped by poverty, Dhanujakumari has fond memories of her childhood. She recalls the large group of children in the slum who played and lived together. The estranged relationship between her parents often resulted in interruptions to her studies. Little Dhanuja had to change schools several times. The children in Chengalchoola were not good at academics, she recollects, mostly because of the troubled relationships within families and the drinking habits of the elder male members. However,66jogo she fondly and proudly remembers how deeply secular Chengalchoola was. “We all lived together; interfaith/intercaste marriages were not unusual among us. There were five or more castes and religions even within one family,” she says.

While world number two Zverev must now bounce back from another frustrating run, having failed to make it beyond the quarters at any of the events he has played since losing to Jannik Sinner in the Australian Open final, Tien can celebrate becoming the youngest American player to beat an ATP top-three-ranked opponent since Andy Roddick did so in 2001.

Since the ATP rankings were first published in 1973, Tien (19 years, 87 days) is now the youngest player to win his first two matches against ATP top-five opponents, and only the second American overall, after Jimmy Connors.

Zverev's defeat was not the only shock result at the ATP 500, as fifth seed Ben Shelton lost 7-6 (7-3) 6-3 to David Goffin.

Casper Ruud, Tommy Paul and Holger Rune were big-name exits, though they withdrew due to a combination of illness and injury.

That trio will now look to get back to full fitness ahead of the Indian Wells Open.
