Kiwi golfer Lydia Ko has made a strong start to the latest LPGA Tour event in Indianapolis.

Ko begun the tournament with a six-under 66 to sit in a share of fifth place. The world number 17 sits two shots behind American Angel Yin.

The two-time major winner had a hot start with three birdies over her opening four holes to be three-under through nine.

Ko followed that up with four straight birdies on the back nine to move to seven-under before a double bogey halted her run. However she picked up an eighth birdie at the 17th hole and finished at six under.
