Thanasi Kokkinakis has blitzed his way into the round of 64 at the Indian Wells Masters with a barnstorming straight-sets victory over American Brandon Holt.

The Australian delivered nine aces in the 6-4 6-1 triumph, winning all of his points on first serve while forcing 10 break-point opportunities, four of which he converted.

Holt couldn't muster a single break point against the dominant and determined world No.94, who had to go through qualifying to get into the main draw in California.

However, the 26-year-old from Adelaide will need to be at his best next up when he takes on top seed Carlos Alcaraz.

Kokkinakis is joined in round two by compatriots Rinky Hijikata, Alexei Popyrin, Jason Kubler and Jordan Thompson.

Hijikata was a 6-4 7-5 winner over Swede Mikael Ymer, Popyrin beat China's Zhizhen Zhang 6-4 5-7 6-1 on Thursday while Kubler and Thompson were victorious on Wednesday.

Popyrin will face ninth seed Hubert Hurkacz of Poland next, while Hijikata will take on 30th-seeded Argentine Sebastian Baez.

Aleksandar Vukic was also in action but the Australian qualifier couldn't go past three-time grand slam champion Stan Wawrinka.

Wawrinka made a successful return to the tournament after four years away with a 6-4 1-6 6-1 victory.

The 37-year-old Swiss, who has been ranked as high as No.3 and is now No.100 after a series of operations to his left foot and left knee, hit 10 aces and won 28 of 33 first-serve points.

The runner-up to Roger Federer at Indian Wells in 2017, now faces No.26 seed Miomir Kecmanovic at the first Masters 1000 tournament of the season.

Three-time grand slam winner Andy Murray remains unbeaten this season in matches that go to a deciding third or fifth set by coming back to beat Tomas Martin Etcheverry 6-7 (7-5) 6-1 6-4 in a clash lasting more than three hours.

"I've been fighting my hardest. I really want to make the most of these last years that I've got," said the 35-year-old Murray.

"I've managed to fight through some brutal matches. It's been incredible really.

"I don't want it to stop. I know it will at some stage but while it's going like this, might as well enjoy it."

Elsewhere, Jack Draper overwhelmed qualifier Leandro Riedi 6-1 6-1 to set up an all-British matchup against No.24 Dan Evans while Mackenzie McDonald defeated Filip Krajinovic 6-3 6-0.
