| When he ran into Rafa Nadal in the fourth round, it seemed like 
				game over even before he stepped on court for the showdown with 
				the 23-times Grand Slam champion.
 
 Incredibly, not only did the 24-year-old topple Nadal but he now 
				stands just two wins away from becoming the first American man 
				since Andy Roddick in 2003 to lift the U.S. Open trophy.
 
 To get a chance to do that, however, he will have to navigate 
				past the man tipped to be the next big thing in tennis - on-fire 
				Spanish teenager Carlos Alcaraz.
 
 "(It) put my mind at ease that Nadal is out of the way," a 
				grinning Tiafoe told reporters following his win over Russian 
				Andrey Rublev in the quarter-finals.
 
 Alcaraz, however, will be no pushover. Twelve months after 
				reaching the last eight on his Flushing Meadows debut, the 
				19-year-old Spaniard has returned as the third seed and showed 
				his determination to go all the way by grinding out back-to-back 
				five-set victories to reach the last four.
 
 He battled into the early hours of Thursday to down Jannik 
				Sinner in a gruelling, five-hour, 15-minute quarter-final, which 
				kept him in the running to become the youngest ever player to 
				climb to the top of the ATP rankings by the end of the 
				tournament.
 
 "It's going to be really, really tough," Alcaraz, who lost to 
				Tiafoe in their only previous meeting, told reporters.
 
 Like Tiafoe, this is his first Grand Slam semi-final.
 
 "Everybody knows the level of Frances... He's playing 
				unbelievable right now," said Alcaraz. "I feel great to be in my 
				first semi-final in a Grand Slam. I feel better reaching 
				semi-final here in U.S. Open."
 
 TENNIS SKILLS
 
 Norwegian fifth seed Casper Ruud, who also has a link to Nadal 
				having honed his tennis skills at the Spaniard's tennis academy 
				in Mallorca, is the other player in contention to dethrone 
				Daniil Medvedev as world number one.
 
 To keep his hopes of a maiden Grand Slam title and climbing to 
				the top of the rankings alive, the French Open finalist will 
				need to find a way past Russian Karen Khachanov.
 
 While Ruud is known to thrive on clay, winning three titles on 
				the surface this year as well as finishing runner-up to Nadal at 
				Roland Garros, he showed his hardcourt credentials by reaching 
				the Miami final this year.
 
 "I'm honestly a bit surprised that I made it to the semis here," 
				said Ruud, who produced a dominant performance over Italy's 
				Matteo Berrettini in the quarter-final.
 
 "I have developed my hardcourt game a lot the last year or two, 
				and I think Miami this year showed me - and I proved to myself - 
				that I can beat good players and reach later stages in big hard 
				court tournaments."
 
 Khachanov had a rough run-up to New York when he suffered early 
				exits in Washington, Montreal and Cincinnati but showed he could 
				hold his nerve even in the toughest moments when outlasted fiery 
				Australian Nick Kyrgios in a five-set quarter-final.
 
 "It's like one more step forward," said Khachanov, who had never 
				before made it past the third round at the U.S. Open. "I'm 
				really, really happy I could do it."
 
 A first-time Grand Slam winner is guaranteed in Flushing 
				Meadows, with the last four men left standing never having 
				hoisted a major trophy.
