MELBOURNE, Australia (AP) — Jannik Sinner wasn't shaky or lucky to survive this time and the only thing really hot on Monday was his streak, which now stands at 18 straight wins at the Australian Open.
The two-time defending champion had a 6-1, 6-3, 7-6 (2) win over fellow Italian Luciano Darderi to reach the quarterfinals for a ninth consecutive Grand Slam event.

Sinner struggled two days previously with the extreme heat and cramping in the afternoon win over No. 85-ranked Eliot Spizzirri, when he only took control after the roof was closed.
In an evening match in cooler conditions, Sinner was cruising until Darderi lifted his tempo in the third set. Second-ranked Sinner missed match points in the 10th game on Darderi's serve but then took it up a notch in the tiebreaker.
“I felt quite good out there physically. Everything was okay today,” said Sinner, who had limited practice on his off day between his third and fourth-round matches. “Let’s see what’s coming in the next round.”
It'll be a familiar foe. No. 8-seeded Ben Shelton beat No. 12 Casper Ruud 3-6, 6-4, 6-3, 6-4 in a night match on Rod Laver Arena.
Sinner has won his last eight meetings with the 23-year-old American, including their semifinal here last year.
“I have a lot more that I want to do here, and I’ve got a lot to prove,” Shelton said. “I’ll be ready to go.”
Sinner, toward the end of his first official head-to-head with Darderi, had to improve to handle the sudden increased speeds of his rival's forehand.
Darderi saved two match points on his serve in the 10th game of the third set and took the first two points of the tiebreaker. He had to pause for a few moments then before serving because of a baby crying in the crowd at Margaret Court Arena.
He didn't win another point. Sinner reeled off the next seven to triumph in 2 hours and nine minutes.
It extended Sinner's unbeaten streak to 18 against other Italians on tour.
“It was very, very difficult. We’re good friends off the court,” Sinner said. “Third set I had some break chances, I couldn’t use them. I got tight, so very happy I closed it in three sets.”
Sinner had 19 aces — a personal record — and no double-faults. He also wanted to emphasize some minor changes to his game, including going to the net and trying to mix up his game.
In a tough hold in the third set, Sinner saved a breakpoint by changing the direction of the rally with a forehand drop shot, bending his knees low, and winning a crucial point. With a serve-and-volley, he held the game.
“Still room to improve, but very happy with how I’ve come back,” he said. “Now for sure, it (the serve) is a bit more stable. I try to go more to the net and being more unpredictable.”
The left-handed Shelton will throw everything he can at Sinner, who is aiming to become the fifth man in the Open era to win three straight Australian titles.
Shelton is into the quarterfinals for the third time in four years.
“I’m definitely a competitor. I’m rowdy on the court. I look forward to rowdy crowds,” he said. “And down here in Australia, there’s no shortage.”
Shelton said he's a more “locked in” player than he was 12 months ago and he's growing in confidence.

SEOUL, South Korea (AP) — French President Emmanuel Macron and South Korean President Lee Jae Myung agreed Friday to work together to help reopen the Strait of Hormuz and ease global economic uncertainties caused by the war in the Middle East.
Their summit in Seoul came as U.S. President Donald Trump slammed allies for not supporting the U.S. and Israeli war against Iran. Macron was making his first visit to South Korea since taking office in 2017, as part of an Asian tour that already has taken him to Japan.
Macron told Lee at the start of the meeting that the two countries can play a role in helping to stabilize the situation in the Middle East, including Iran’s chokehold on the Strait of Hormuz, which has unleashed shock on global energy markets.
At a joint televised briefing afterward, Macron underscored the need for France and South Korea to cooperate to help reopen the strait and deescalate Middle East animosities, while Lee said the two affirmed “their resolves to cooperate to secure the safe shipping route in the Strait of Hormuz.”
The two leaders did not take questions and did not elaborate on how they would help reopen the strait — the narrow waterway between Iran and Oman through which about one-fifth of the world’s oil usually passes.
“We need to clearly define, at the international level, the conditions for a process to ease the crisis and conflict in the Middle East,” Macron said. “We need to ensure that the Strait of Hormuz is reopened.”
Lee said he and Macron agreed to expand cooperation in technology, energy and other areas. South Korean and French officials also signed agreements to cooperate on nuclear fuel supply chains, jointly invest in an offshore wind project in southern South Korea and to collaborate on critical minerals. South Korea has moved to increase output at its nuclear reactors to mitigate the energy crunch and Lee has also called for a faster transition to renewable energy, saying the war has exposed the country’s heavy reliance on fossil fuel imports.
Macron’s Asia trip comes as Trump has ramped up his frustration with allies. In a speech Wednesday, Trump said Americans “don’t need” the strait but the countries who do “must grab it and cherish it.”
In an earlier Easter event at the White House, Trump called for his allies in Asia and China to get involved in reopening the waterway.
“Let South Korea, you know, we only have 45,000 soldiers in harm’s way over there, right next to a nuclear force — let South Korea do it,” Trump said. “Let Japan do it. They get 90% of their oil from the strait. Let China do it.”
The United States stations about 28,000 troops in South Korea, not the 45,000 stated by Trump. The U.S. troops’ deployment in South Korea is meant to deter potential aggressions from North Korea.
Macron has said reopening the Strait of Hormuz through a military operation is unrealistic.
South Korean officials have said they are in contact with Washington on the issue and that Seoul isn’t considering paying Iran transit fees to secure fuel shipments through the strait.
