World number one Jannik Sinner will continues his Australian Open title defence against American 21st seed Ben Shelton in the night session on Rod Laver Arena on Friday.
Sinner easily dispensed with home favourite and eighth seed Alex de Minaur in the quarter-finals and looks to have shrugged off the medical issue that left him dizzy and shaking against Holger Rune in the last 16.
While Sinner is into his fifth Grand Slam semi-final, Shelton, who turned pro in 2022, is set to play just his second after reaching the last four at the 2023 US Open.
Sinner holds a 4-1 head-to-head record against Shelton but the 23-year-old Italian remains cautious ahead of their clash.
"One of the biggest serves we have on tour," Sinner said. "He's a very aggressive player, an all-around player. He can go to the net. He can stay back.
"It's a difficult match for both of us. We know each other a little bit better now. We had some tough matches in the last year, so let's see what's coming."
