The 25-year-old Rublev was at his heavy-hitting best against the fourth seed in his opening Red Group match. He struck 25 winners across the second and third sets, opening up Medvedev's defence in the fast indoor conditions with his flat and precise groundstrokes before outlasting Medvedev in an epic 37-shot rally to finally seal victory on his fifth match point in the third-set tie-break.

After charging to the opening set, Rune held firm to force a tie-break as World No.1 Alcaraz stepped up his level in the second. Having had treatment on an abdominal muscle at 6-5, however, Alcaraz was forced to retire with Rune leading 3/1 in the second-set tie-break at 6-3, 6-6.

The ATP, International Tennis Federation (ITF) and tournament promoters Kosmos have signed a deal on Monday. The men's World Cup of Tennis is the longest-running and largest annual international team event in sport with 122 years of history. The new partnership has been established to enable strategic collaboration on the competition's governance and evolution, with ATP granted two of six seats on a newly formed Davis Cup Event Committee alongside the ITF and Kosmos, long-term investors and promoters of the competition.

It was the third consecutive ATP Tour title for the Canadian player. "It's been an amazing week. Once again in the final, not getting broken all week... (It's been) a long year, a long stretch of wins, and it's not over. So hopefully I can keep going, but right now I'm feeling all the good emotions that come with winning a tournament. It's amazing," said Auger-Aliassime after the match.

"It feels really good of course. You know you're on the right path and this gives you that extra cherry on top, I feel," Middelkoop said. "Not even [winning the title] title, I think the way we played today showed what we are capable of and I think that's the most important thing for me, what I take out of this day," he added.

The reforms follow an in-depth review and strategy development, conducted by ATP's new senior Challenger Tour team over the past eight months, according to a statement issued by ATP.

The 26-year-old from Southend-On-Sea, Essex, who had not played a tour-level match entering last week's event at Queen's Club, on Tuesday rallied past ATP NextGen star Holger Rune of Denmark, winning 4-6, 7-6(5), 6-1 to reach the second round. Eighth seed Rune held a mini-break advantage at 4/3 in the second-set tie-break and was within two points of victory at 5/5, but was unable to convert.

In a match of changing fortunes, both players stood tall behind their serves and could not be separated until late in each set. A relieved Hurkacz conceded after the match that only a couple of shots made the difference between victory and defeat. "One or two shots (was the difference)," Hurkacz was quoted as saying by atptour.com. "Definitely super close. Nick played a really, really great match. He's a great player, so it was definitely a super tough one.

"The ability for players of any nationality to enter tournaments based on merit, and without discrimination, is fundamental to our Tour. The decision by Wimbledon to ban Russian and Belarusian players from competing in the UK this summer undermines this principle and the integrity of the ATP Ranking system," the ATP said in a statement.

The Indian youngsters beat their higher-ranked rivals 6-2, 6-4 en route to the last-eight stage of the doubles event. Arjun Khade, who will take on third seed Frenchman Enzo Couacaud in the singles pre-quarterfinal match on Thursday, combined with Austrian Alexander Erler to breeze past the duo of Bogdan Bobrov (Russia) and Dominik Palan (Czech Republic) with a 6-0, 6-3 victory.
