NEW YORK (AP) — Alexander Zverev rallied just in time to avoid becoming the first men's No. 1 seed to lose in the first round of a Grand Slam tournament since 2003, edging Lorenzo Sonego 6-4, 3-6, 6-7 (7), 7-5, 6-4 in a U.S. Open match that ended Wednesday morning.
Zverev couldn't cash in on repeated chances to break Sonego's serve for much of the night and was in danger of becoming the first top-seeded man to fall in his first match in a major since Ivo Karlovic beat Lleyton Hewitt at Wimbledon in 2003.

It hasn't happened at the U.S. Open since Stefan Edberg lost to Alexander Volkov in 1990. Zverev finally broke through against Sonego's serve late to pull out the match in 4 hours, 52 minutes.
“Nearly five hours for a first round, I think this is the longest first-round match I’ve ever played in my life,” Zverev said. “So, credit to him. He played amazing tennis today, would have beaten a lot of players for sure, but I’m happy to be through.”
Zverev won his first major title at the French Open, lost to top-ranked Jannik Sinner in the Wimbledon final, then became the No. 1 seed in a major for the first time when Sinner had to withdraw from the U.S. Open with a right knee injury.
Zverev is 7-0 against Sonego, an Italian who came in 1-9 against top-10 men in Grand Slams. But Sonego's speed around the court allowed him to track down balls that on other nights would have been winners, and he came up with enough clutch serves to make Zverev just 5 for 22 on break points for the match.
The German broke when Sonego served for the third set at 5-4 and seemed to be in good shape in the tiebreaker when he hit consecutive serves of 133 mph and 141 mph to take a 7-6 lead. Sonego won the next two points to take the lead and Zverev then double-faulted to end the set.
Zverev then broke for a 3-2 lead in the fourth set, but Sonego raced from corner to corner of the court in the next game to break right back. Sonego then got within two points from winning the match with a 5-4 lead, but Zverev held serve and then broke to go ahead 6-5.
Sonego had his hand or wrist checked before the start of the final set. He appeared OK afterward but Zverev got the break he needed to grab a 3-2 lead and stayed ahead from there.
Zverev advanced to face Quentin Halys in the second round, and the 2020 U.S. Open runner-up wasn't disappointed that he needed to work so hard to get there.
"Actually I’m happy that I won this kind of battle because this exactly the match that I needed," he said. “I struggled the last two tournaments, I didn’t play well and sometimes good things happen after you fight through one of these matches. So I’m hoping that will be the case for me at this tournament.”

U.S. Sen. Ed Markey secured the Democratic nomination in Massachusetts’ Senate primary Tuesday, once again fending off a push for generational change as he seeks a third term.
Markey, 80, defeated U.S. Rep. Seth Moulton, 47, who had attempted to argue that it was time to do away with the “status quo” in his pursuit to oust the octogenarian.
Yet Markey successfully pointed to Moulton’s more moderate positions to argue that it was Moulton — not the older incumbent — who was out of touch with the state’s voters. Perhaps no other issue defined the race more than transgender rights, and Markey repeatedly hit Moulton for previously saying he would not want his daughters to play against transgender athletes.
“Massachusetts needs a senator who stands up and fights back, a senator who never forgets who they are fighting for,” Markey said during his victory speech. “That has been the mission of my life, and it always will be.”
In heavily Democratic Massachusetts, the primary is considered the most critical election hurdle, where Democratic winners are expected to prevail in the general election in November. Markey will face Republican John Deaton, who who lost to Sen. Elizabeth Warren by about 20 points in 2024 and was unopposed in his primary Tuesday.
Markey has been a fixture in Massachusetts politics since the 1970s, prompting Moulton to make his “status quo” arguments on the campaign trail and to question Markey’s accomplishments during his lengthy time in office.
“Generational change isn’t about compromising, to do the small things better,” Markey said Tuesday. “It’s about fighting to do the big things best.”
In a concession speech, Moulton said he would now support Markey.
“Challenging the establishment and calling for a new generation of leadership isn’t easy. But it is necessary,” Moulton told supporters. “We started conversations that needed to happen.”
“We didn’t achieve our goal tonight, but I am confident others will be inspired to buck the system when they’re told to wait their turn,” he added.
The Senate race was not the only generational challenge for Democrats on the ballot. Similar dynamics played out in several congressional races, but ultimately, the older incumbents won Tuesday. In the 8th Congressional District, longtime incumbent Rep. Stephen Lynch defeated Patrick Roath. And in the 1st Congressional District of western Massachusetts, Rep. Richard Neal defeated public school teacher Jeromie Whalen to advance to the general election.
During the campaign Markey repeatedly pointed out that Moulton, in 2024, raised eyebrows among some in the party for saying he did not want his daughters playing sports against transgender girls.
Critics said he was echoing President Donald Trump’s talking points against allowing transgender athletes in girls’ and women’s sports.
Moulton later apologized for his remarks, saying it was not his intention to hurt the transgender community and stressing his support for other transgender rights bills.
“If you’re in the trans community or you’re a trans kid feeling the weight of the Trump administration and the Supreme Court, you matter,” Moulton said during an August debate. “You’re valued, and I will always have your back.”
Moulton, who enlisted in the Marines after the attacks on Sept. 11, 2001, and served four tours of duty in Iraq, was first elected to Massachusetts’ 6th Congressional District in 2014. He launched a 2020 presidential campaign but dropped it after a few months.
Markey was elected to the Senate in 2013. Before that he represented Massachusetts’ 7th Congressional District from 1976 to 2013.
Markey notably fended off a challenge in 2020 from Rep. Joe Kennedy III, a younger rival from one of the nation's most famous political families. Markey did so by aligning himself with the liberal wing of the Democratic Party.
Antoine Hilaire, a 76-year-old Democrat who voted for Markey in Brockton on Tuesday, said being older can be a positive because it offers people experience and wisdom.
“If the older one is doing the better job, I don’t know,” he said. “He’s doing a good job. It’s not a big, big, big problem.”
Lynch, 71, has held the 8th District seat in south Boston since 2001. He won Tuesday's primary against Roath, a 39-year-old lawyer who contended that it is time to end “wait-your-turn” politics. Lynch stressed the value of experience inside Congress.
Lynch has fended off other youth challenges in the past, but Roath’s campaign hoped for a boost of excitement after longtime Democratic incumbent U.S. Rep. John Larson was defeated by former Hartford Mayor Luke Bronin in August in neighboring Connecticut. Like Roath, Bronin called for the need for generational change while running against an establishment politician.
In the 1st District Democratic primary in western Massachusetts, Neal, 77, bested Whalen, 39.
Neal, known as the dean of the New England House delegation, was first elected in 1988. Whalen ran to the left of Neal, calling for Medicare for All and questioning whether Neal has done enough to oppose Trump’s agenda.
Whalen was endorsed by Our Revolution, a progressive organization founded by Sen. Bernie Sanders of Vermont.
Associated Press reporter Leah Willingham in Brockton contributed.
The story has been updated to correct Larson’s first name to John, not Jim.
