NEW YORK (AP) — Madison Keys moved into the second round Tuesday at the U.S. Open, where rain threatened to hamper the schedule for a couple days.
Showers that began Monday night and would possibly be on and off through the middle of the week delayed play on all the outer courts, allowing for action only in Arthur Ashe Stadium and Louis Armstrong Stadium, which have retractable roofs.

Keys, the No. 22 seed, beat 19-year-old Alina Korneeva 7-5, 6-4 in the leadoff match in Ashe. The 2017 U.S. Open runner-up was knocked off in the first round last year in Flushing Meadows.
“It’s always tough playing someone young and up and coming, and they’re going after their shots,” Keys said. “And it’s so hard to play a first round of a Grand Slam, so nervous and just wanting to do so well. So, really happy I was able to kind of fight through that and win today.”
Flavio Cobolli, the men's No. 5 seed, quickly dropped the first two sets against Francisco Comesana on Armstrong in the only other match that was ongoing in the early afternoon.
Among those who were supposed to be playing already but had to wait were No. 2 seed Elena Rybakina, No. 12 Belinda Bencic and No. 32 Maria Sakkari.
Rybakina has multiple routes to the No. 1 ranking at the U.S. Open. She was facing American Thea Frodin, a 17-year-old from California who was the body double for actor Demi Singleton, who played Serena Williams, in the 2021 film “King Richard.”
Coco Gauff, the 2023 U.S. Open champion, No. 17 Alex Eala, and men’s No. 1 seed Alexander Zverev were scheduled at night on the third and last day of the first round.
Keys was broken when serving for the match with a 5-3 lead but recovered to break back in the next game and finish up the match.
The American lost to Sloane Stephens in the 2017 U.S. Open final and returned to Flushing Meadows last year after winning the first major title of her career by beating No. 1 Aryna Sabalenka in the Australian Open final. But what started out as a great year fell flat at the finish after Keys was stunned by Renata Zarazua of Mexico after committing 89 unforced errors.

Stocks fell Tuesday and oil prices continued to climb following another round of U.S. military strikes on Iran, stoking worries about stubbornly high inflation.
The S&P 500 index fell 0.7%. The Dow Jones Industrial Average fell 456 points, or 0.9%, as of 1:26 p.m. Eastern time. The Nasdaq composite fell 1%.
The weak start to September follows a shaky but mostly positive month for Wall Street. Every major index notched monthly gains in August. The same worries continue to hang over Wall Street, though, including anxiety over rising prices, government debt, and the impact of global conflicts on the U.S. and the global economy.
Technology stocks were among the heaviest weights on the market. Microsoft fell 1.3% and Advanced Micro Devices fell 3%. Their big market values tend to give them more influence over the broader market’s direction and their growth amid the artificial-intelligence boom has been heavily reliant on borrowing, which becomes more expensive as interest rates rise.
Much of the continued pressure being felt by Wall Street is coming from an ongoing sell-off in U.S. government bonds. The yield on the 10-year Treasury, which tends to impact mortgage rates, rose to 4.79% from 4.75% late Monday. It was as low as 4.20% at the beginning of 2026
The yield on the 2-year Treasury, which closely tracks expectations for Federal Reserve moves on interest rates, rose to 4.38% from 4.34% late Monday. That’s up significantly from about 3.50% at the beginning of 2026.
Bond yields have an inverse relationship to prices, and yields rise as prices fall. Rising yields signal that investors are demanding a higher return from Treasurys because they are becoming riskier. Growing government debt is highlighting that risk.
The U.S. debt surpassed $40 trillion two weeks ago, a shocking milestone as defense costs and interest on the burgeoning deficit make up an enormous share of federal spending. The bond sell-off is global, with other nations facing the same economic pressures.
Higher yields on bonds signal higher borrowing costs on mortgages and a wide range of other loans. Higher borrowing costs tend to weigh down investments, including stocks, while making it more difficult for businesses to expand.
Oil prices have been behind much of the pressure on inflation, bond yields and the broader stock market. The price of Brent crude, the international standard, rose 3.9% to $94. Energy costs remain high and volatile amid the ongoing U.S. war with Iran, which has essentially shut down the Strait of Hormuz, through which 20% of the world’s oil is typically shipped.
Higher oil prices have pushed up costs for everything from gasoline to shipped goods, fueling inflation that has been squeezing households and businesses. Higher inflation has also been a problem for the Fed, which is aiming to bring inflation down to a 2% rate.
The rate of inflation is well above 3%, and Wall Street expects the Fed to raise interest rates before the year is over in order to ease the rate of price increases. Investors are betting on a 66% chance that the central bank will raise its interest rate at its upcoming September meeting, according to CME FedWatch.
The Fed will get more updates on inflation ahead of the meeting. Meanwhile, it is getting updates on the jobs market this week. On Tuesday, the government reported that U.S. job openings rose slightly in July. A broader monthly report for August will be released on Friday.
Markets in Europe fell and markets in Asia were mixed.
