Spanish star Sergio Garcia and American Peter Uihlein have both fired six-under par rounds of 64 to move into a three-way tie for first place after the second round at LIV Golf Hong Kong.

Uihlein finished his uneven round with one eagle, eight birdies and four bogeys to join Garcia and first-round leader Paul Casey (66 on Saturday) at 11 under at Hong Kong Golf Club on Saturday.

Garcia had six birdies and Englishman Casey added four during their respective bogey-free rounds.

"I just watched the Peter Uihlein show today," Casey said.

"It was impressive stuff. I'm very happy that I'm sitting here tied for the lead. If Pete had not made a bogey today, he'd be about five shots ahead because of his firepower."

"I've had four runners-up, so getting that first win would be awesome," said Uihlein.

"I think that's kind of the goal at the start of every year is to get a win. To get a team win would be nice as well, but an individual win would be fantastic."

Mito Pereira highlighted his own stellar 64 on Saturday with the 10th hole-in-one in LIV Golf history.

The Chilean aced the 149-yard second hole as part of his round and joined Torque GC teammate Sebastian Munoz (67) of Colombia and Phil Mickelson (65) in a tie for fourth place at eight-under.

Mickelson, who's yet to win a LIV event, kept in the hunt after carding seven birdies and two bogeys.

Australian Lucas Herbert is in an eight-way tie for seventh place after his four-under round of 66.

Herbert's all-Australian Ripper GC team were eighth out of the 13 outfits in the team competition at 16 under, while Pereira and Munoz inspired Torque GC to go top at 25 under.
