(REUTERS) - Australian Minjee Lee fired a bogey-free six-under 66 on Oahu's Ko Olina course on Thursday to take a two-shot lead after two rounds at the Lotte Championship in Hawaii.

Lee, who finished in a tie for 13th last year, took advantage of calm afternoon conditions and rode a strong mid-round stretch to seize control.

The 19-year-old birdied three successive holes from the par-four 11th before parring the last five to finish at 10 under, two better than American Katie Burnett.

"I holed a couple of nice putts (today) and just got my momentum going on the front nine," Lee told reporters.

"I birdied eight and nine, so I think the momentum carried on through the back nine."

South Korea's Su Yeon Jang is third at seven under.

World No. 1 Lydia Ko stalled with an even-par 72 and is one under for the tournament.

Michelle Wie improved on her opening round 80 with a one-over 73 but failed to make the cut at her hometown event.
