Alexei Popyrin has powered into the second round at an ATP 250 tournament in Singapore.
The 21-year-old Australian fired 15 aces in a 7-6(5) 7-6(5) opening-round victory against American qualifier Christopher Eubanks.
It was a steely effort from world No.114 Popyrin, who saved 10 of the 11 break points he faced in the one-hour and 46-minute battle.
It continues a strong start to the season for the Australian, who made the third round at the Murray River Open earlier this month and defeated No.13 seed David Goffin in a career-best win at the Australian Open.
This victory against Eubanks marks the first tour-level main draw match Popyrin has won outside of Australia since October 2019.
Bulgarian wildcard Adrian Andreev awaits in the second round, with the 19-year-old upsetting seventh seed Lloyd Harris to advance.
