The 22-year-old West Australian boasts a European Tour win at last year's co-sanctioned Victorian Open and was United States Junior Amateur champion in 2016.

But sister and current World No.8 Minjee Lee also won the equivalent junior title  they are the only siblings to achieve the feat  and already has five victories on the American Tour as well as an Olympic Games appearance to her name.

"I get a bit of grief sometimes about being in her shadow a bit," he wrote in a diary for the PGA Tour website this week.

"So it's become kind of a motivation for me.

"She's been a good mentor since I turned professional ... she works so hard and it's been fun to drive each other on."

Minjee has enjoyed the friendly rivalry and tight bond, which began when her younger brother would pester her at the driving range or practice green.

"I get a bit of grief sometimes about being in her (sister Minjee's) shadow a bit ... So it's become kind of a motivation for me." – Min Woo Lee

"A lot of people were saying 'this is Minjee's brother' and I think that kind of got on his nerves a little, but he's writing his own book now which is cool to see," she said.

"Min Woo has a brighter personality (than me); he loves the crowds and he rides on the momentum through the crowds as he's a fiery spirit.

"Those (LPGA) wins drive him ... he sees me doing well, he wants to do well too and I'm sure he will."

Lee is one of nine Australians in the Pebble Beach Pro-Am field, including Jason Day and the in-form Cameron Davis, beginning on Friday (AEDT).

This year's tournament, staged on the picturesque Californian coastline, won't feature the traditional amateur component or spectators becaue of COVID-19.

With a full European Tour exemption until the end of next year, Lee has sought advice from former World No.1 Day as he seeks the results to seal a permanent move to the United States.

"He gave me a few words of wisdom and a bit of experience from himself," Lee said.

"It's a dream come true to get a start on the PGA Tour and hopefully I capitalise on it."
