Defending champion Carlos Alcaraz defeated Frances Tiafoe in five sets to reach the Wimbledon last 16 on Friday, while Jannik Sinner and Coco Gauff advanced with ease.
Alcaraz won 5-7, 6-2, 4-6, 7-6 (7/2), 6-2, serving 16 aces and hitting 55 winners in a match that lasted nearly four hours.
"Always a big challenge playing against Frances," said Alcaraz. "He is a really talented player, really tough to face."
Alcaraz, aiming to become the sixth man to win the French Open and Wimbledon titles back-to-back, has now reached the last 16 of a Slam for the tenth time. He and Tiafoe shared a warm embrace at the net.
"Just ultimate respect. Him just saying, 'It's good to see you play like that.' Me just saying, 'I can't stand you,'" joked Tiafoe.
World number three Alcaraz will next play either Ugo Humbert or Brandon Nakashima. That match was among four men's third-round clashes delayed by heavy rain in London.
World number one Sinner defeated Miomir Kecmanovic 6-1, 6-4, 6-2 in just 96 minutes. Sinner, the 2023 Australian Open champion, will next face either Denis Shapovalov or Ben Shelton. This win marked Sinner's 41st of the season, surpassing Casper Ruud's 40 wins.
Women's world number two Gauff ended the run of British qualifier Sonay Kartal, winning 6-4, 6-0, and allowing her opponent just eight points in the second set.
"This is my first time playing a British player here, so I was a little nervous because I knew you'd be for her, which is understandable," said Gauff. "Thankfully you guys were pretty nice to me, so that helped."
Gauff will face American compatriot Emma Navarro for a place in the quarter-finals.
Tommy Paul, the US men's 12th seed, reached the fourth round for the second time with a 6-3, 6-4, 6-2 win over Alexander Bublik. Paul, who won the Queen's Club title just before Wimbledon, said, "I'm having fun on the grass."
Grigor Dimitrov, a semi-finalist ten years ago, defeated 37-year-old Gael Monfils in straight sets.
Two-time quarter-finalist Madison Keys, the 12th seed, reached the second week for the fifth time with a straight-sets win over Marta Kostyuk. Keys will face French Open runner-up Jasmine Paolini, who had never won a match at Wimbledon before this year. Paolini defeated former US Open champion Bianca Andreescu in straight sets.
Lulu Sun became the first woman from New Zealand since 1959 to reach the last 16, winning 7-6 (7/4), 7-6 (8/6) over China's Zhu Lin. Sun, who came through qualifying, hopes her win will be headline news in her hometown of Te Anau.
"Practically more sheep and deer than people," joked Sun. She will next face Emma Raducanu, who reached the last 16 of a major for the first time since her 2021 US Open win. Raducanu defeated ninth-ranked Maria Sakkari 6-2, 6-3 for her second win over a top-10 player.
"Today was really up there with the most fun I've had on a tennis court," said Raducanu.
Donna Vekic needed nine match points to defeat Dayana Yastremska 7-6 (7/4), 6-7 (3/7), 6-1 in a match lasting just under three hours. Vekic will next face Spain's Paula Badosa.
Bhambri-Olivetti pair ousted from Wimbledon
India’s Yuki Bhambri and his French partner Albano Olivetti exited Wimbledon in the second round, losing to Germany’s Kevin Krawietz and Tim Puetz in three sets. The pair lost 6-4, 4-6, 3-6 to the eighth-seeded Germans in two hours and five minutes on Friday. Bhambri and Olivetti had defeated Alexander Bublik and Alexander Shevchenko in the opening round.
Veteran Rohan Bopanna and his Australian partner Matthew Ebden, the reigning Australian Open champions, will play Germany’s Hendrik Jebens and Constantin Frantzen in the second round on Saturday. Bopanna is the only Indian left in the tournament after Sumit Nagal and N. Sriram bowed out earlier this week.

Anurag Bajpayee's Gradiant: The water company tackling a global crisis
In a world increasingly defined by scarcity, one resource is emerging as the most quietly decisive factor in the future of industry, sustainability, and even geopolitics: water. Yet, while the headlines are dominated by energy transition and climate pledges, few companies working behind the scenes on water issues have attracted much public attention. One of them is Gradiant, a Boston-based firm that has, over the past decade, grown into a key player in the underappreciated but critical sector of industrial water treatment.
A Company Born from MIT, and from Urgency
Founded in 2013 by Anurag Bajpayee and Prakash Govindan, two researchers with strong ties to the Massachusetts Institute of Technology (MIT), Gradiant began as a scrappy start-up with a deceptively simple premise: make water work harder. At a time when discussions about climate change were centred almost exclusively on carbon emissions and renewable energy, the trio saw water scarcity looming in the background.
Their insight was that some of the world’s largest industries—semiconductors, pharmaceuticals, chemicals, food and beverage—were facing acute water-related challenges long before the general public grasped the issue. “Without water, these industries don’t just slow down; they stop,” Bajpayee has often remarked. What Gradiant offered was not just a way to save water, but a way to rethink how it is used, recycled, and valued.
The Engineers Behind the Mission
Anurag Bajpayee, the company’s CEO, whose academic path took him to MIT, where he completed a PhD in Mechanical Engineering focused on water treatment technologies. It was there that he met Govindan, a fellow engineer and now Gradiant's co-founder and COO, whose expertise complemented his in fluid mechanics and process engineering.
Unlike many founders who drift towards the language of venture capital and corporate strategy, Anurag Bajpayee and his team remained grounded in the technical problem: how to make industrial water treatment more efficient, more affordable, and more sustainable. The company still bears the imprint of its founders’ engineering roots. Gradiant is less Silicon Valley startup and more MIT lab, albeit one that has quietly expanded across Asia, the Middle East, Europe and North America.
What Gradiant Actually Does
The company specializes in designing and building bespoke water treatment and reuse systems for industrial clients. Its technologies are aimed at enabling factories and plants to reclaim water that would otherwise be discarded as waste, reducing both the amount of water withdrawn from natural sources and the volume of contaminated water discharged.
At the heart of Gradiant’s portfolio are proprietary technologies such as Counter Flow Reverse Osmosis (CFRO), Carrier Gas Extraction (CGE) and Selective Ion Recovery (SIR), developed from the Gradiant founders’ early research at MIT. Unlike traditional methods like reverse osmosis, these systems are designed to handle highly contaminated or complex wastewater streams, enabling clients to extract clean water even from previously unusable sources.
But Gradiant does not sell “one-size-fits-all” machines. Each project is tailored to the customer’s unique needs. For a semiconductor plant in Singapore, this might mean achieving ultrapure water reuse levels of 98%; for a food and beverage factory in Texas, it might be about safely treating wastewater for discharge while minimising energy consumption. The company's approach—sometimes called "solutioneering" internally—is both its competitive advantage and its raison d'être.
Expansion Without the Usual Hype
Gradiant’s growth has been quietly impressive. From its first commercial project in the oil and gas sector, it has gone on to complete over 500 installations worldwide. The company has raised more than $400 million in funding from a mix of institutional investors and private equity firms, achieving so-called “unicorn” status, with a valuation reportedly over $1 billion.
Unlike many green tech firms, Gradiant’s expansion has not been accompanied by flashy marketing campaigns or grandiose statements. Instead, the company has preferred to build credibility client by client, particularly in Asia, where water-intensive industries and growing environmental pressures make its services indispensable. Anurag Bajpayee, never one to speak in superlatives, frames the company’s expansion as a “response to urgent need” rather than a triumph of business.
Inside Gradiant’s Operations
At its core, Gradiant is still an engineering-first company. Anurag Bajpayee and Govindan, both technically trained and heavily involved in the company’s operations, have instilled a culture where R&D is not just a department but the lifeblood of the business. The firm currently holds more than 250 patents globally, a testament to its ongoing commitment to innovation.
But Gradiant’s success is not just about technology. The company has differentiated itself by offering not just equipment but full-service solutions, including project design, construction, operations, and maintenance. This full-stack approach has been particularly attractive to clients in highly regulated industries, who need water management solutions that work seamlessly and reliably without requiring deep in-house expertise.
Gradiant’s clients include some of the world’s largest manufacturers, including Fortune 500 companies in sectors like microelectronics, pharmaceuticals, and energy. Some, like semiconductor producers, rely on Gradiant to help them meet stringent water reuse targets while maintaining ultra-clean production environments.
Navigating a Changing World
Gradiant operates at the intersection of several converging trends: climate change, regulatory pressure, and industrial decarbonisation. In many regions, water scarcity has become the limiting factor for industrial growth, sometimes more than energy availability or supply chain constraints.
While public attention often focuses on domestic water use, it is industries that consume the lion’s share of freshwater. Gradiant's pitch is straightforward: industries will have to do more with less, and Gradiant offers the tools to make that possible.
Anurag Bajpayee is keenly aware of the paradox that water, despite being vital, is often underpriced and undervalued, especially when compared to energy. “We don’t pay what it’s worth, only what it costs,” he told an audience at a recent conference. Yet, the landscape is shifting. Regulators, investors, and companies themselves are increasingly acknowledging water as both a business risk and a social responsibility.
What's Next for Gradiant?
Looking ahead, Gradiant appears poised to play a central role as industries adapt to water scarcity. Yet, Anurag Bajpayee remains cautious about the hype cycle. "The problem we’re working on isn’t going anywhere," he says. "It’s not a question of innovation alone, but of execution—of making sure these solutions actually reach the places that need them most."
In an era where water risk is increasingly material to business, Gradiant’s quiet, technically grounded approach may prove to be exactly what is needed.
