• Knyba wins unanimous decision after dropping Ruiz

• Former champion struggles badly after 762-day layoff

• Ruiz, 36, insists another title run remains possible

Andy Ruiz Jr’s comeback bid was left in tatters on Friday night after the former unified heavyweight champion was knocked down and picked apart in a sobering unanimous-decision defeat to Damian Knyba in Newark, New Jersey.

Knyba won by scores of 117-110 and 114-113 twice, handing Ruiz the third defeat of his professional career and dealing a devastating blow to his hopes of becoming a two-time champion in boxing’s prestige division. The baffling pair of 114-113 cards flattered Ruiz considerably and bore little relation to the mostly one-way traffic that unfolded. (The Guardian had it 117-110.)

Seven years after springing one of the biggest upsets in boxing history, the Mexican Rocky is back with his old trainer for one final run at the heavyweight summit

Seven years ago, Andy Ruiz Jr became the first fighter of Mexican descent to win the world heavyweight championship in one of the biggest upsets boxing has ever seen, stopping the undefeated Anthony Joshua inside seven rounds at Madison Square Garden.

A replacement opponent summoned on five weeks’ notice who went off as an 11-1 underdog, Ruiz came off the canvas in the third to knock Joshua down four times before the referee finally waved it off. Hailed as the “Mexican Rocky”, he was lionized as a border-straddling hero in his hometown of Imperial, the dusty agricultural community framed by the mountain ranges and flat deserts of south-eastern California. He made the late-night rounds, took an audience with Mexico president Andrés Manuel López Obrador and signed a $10m guarantee when Joshua activated his rematch clause. The money, cars, fame and women arrived all at once.

• Shelton and Tiafoe advance to third round

• Pegula cruises past Kenin in 56 minutes

Michael Zheng spent years making the long trek from northern New Jersey, first by bus across the Hudson River to the Port Authority bus terminal and then nearly the full length of the No 7 subway line, all for the opportunity to train at the USTA Billie Jean King National Tennis Center. On a rainswept Wednesday afternoon in Queens, the destination was the same but the purpose had changed entirely.

The 22-year-old American wildcard and two-time NCAA champion from nearby Columbia University brushed aside Hungary’s Fabian Marozsan 6-4, 6-4, 6-2 to win his rain-delayed US Open debut, providing one of the more unlikely highlights on a busy day for the home contingent in New York.

• Kenin wins 6-2, 7-6 (6) in late-night contest

• Williams loses 15th straight tour-level match

• First-round clash finally begins at 12.13am

Sunday had become Monday by the time Venus Williams finally emerged beneath the closed roof of Arthur Ashe Stadium, her entrance pushed deep into the night after Novak Djokovic’s bruising defeat by Argentina’s Mariano Navone went the five-set distance. The first ball was struck at 12.13am, the latest start to a match in US Open history, yet several thousand spectators remained to watch a player who has been part of this tournament for as long as the building itself.

At 46 years old, ranked 611th in the world and making her record-extending 26th US Open singles appearance, Williams has grown accustomed to making history simply by showing up. Even by those standards this latest installment was, as she would later describe it, “completely insane”.

• US star plans to return for 2027-28 season

• Liu will continue training during year away

• Skater says break ‘makes the most sense’

Olympic champion Alysa Liu will sit out the 2026-27 figure skating season, taking another break from competition while continuing to train ahead of a planned return the following year.

The 21-year-old American announced her decision on social media, saying she wanted time to “recalibrate” and develop her skating away from the demands of competition.

Nearly a decade after I watched him defy Erdoğan at great personal cost, the ex-NBA player is using his hard-won freedom to turn transgender people into a punchline

Nine years ago, I watched Enes Kanter ask America to take him in. It was May 2017, inside the National Basketball Players Association’s offices in midtown Manhattan. Kanter had just returned from a frightening detention at Bucharest airport, where Romanian border police told him Turkey had canceled his passport. He’d just turned 25, an NBA center with a green card and no country he could safely call home.

“I’m open for adoption,” he joked from the head of a table in a nondescript conference room, addressing a dozen reporters hastily summoned by his manager. Then he turned serious: “My next move is to just become an American citizen.”
