British number one Cameron Norrie and Jack Draper continued their preparation for the Australian Open by reaching the semi-finals at their respective warm-up events.
World number 11 Norrie defeated Marcos Giron 6-1 6-7 (5-7) 6-2 in Auckland, New Zealand.
He will face another American, Jenson Brooksby, for a place in the final.
Meanwhile, Draper will play Kwon Soon-woo in the last four in Adelaide after overcoming Russian Karen Khachanov.
The 21-year-old Draper, who has been drawn to play defending champion Rafael Nadal on his Australian Open debut, won his Adelaide International 2 quarter-final against third seed Khachanov 6-4 7-6 (7-3).
Elsewhere, three-time Grand Slam champion Andy Murray, the current British number four, beat Australian world number 24 Alex de Minaur 6-3 6-3 at the Kooyong Classic exhibition event in Melbourne.
The Australian Open, the first Grand Slam tournament of the new season, takes place at Melbourne Park between 16 and 29 January.
Norrie, who will start his Australian Open against French wildcard Luca van Assche, has won all five matches he has played this year.
Aiming to begin the season with a title in the country where he was raised, the 27-year-old Wimbledon semi-finalist made a strong start against world number 60 Giron and settled the ASB Classic contest with a double break in the third.
"It's so good to be back, it's a second home for me, it's great to be playing on this court," Norrie said.
"I made it difficult for myself in that second set. It's kind of annoying not to get it done in straight sets but credit to Marcos."
Following a breakthrough 2022 season, Draper, ranked 40th, dispatched world number 20 Khachanov a week after losing 6-4 6-2 to the same player at the Adelaide International 1 event.
Draper had led 5-3 in the second set and kept his nerve after his opponent forced a tie-break, holding his serve to progress to his second ATP Tour semi-final in straight sets.
"Against guys like Karen, you can't give them an inch or they run away with it," Draper said.
"Last game I got a bit nervous but that's all part of the game. I'm still young, I'm still learning. I did well to impose my game on him."
Murray said he has "no timeframe" on retirement after recording his first win of the season against China's Zhang Zhizhen on Wednesday as he prepares for the Australian Open, where he is a five-time finalist.
