Lydia Ko has moved up the leaderboard into a share of 23rd after the second round of her first tournament as a professional.

Ko equalled her first round 71 to sit on two-under for the tournament at the halfway stage of the LPGA's season-ending Titleholders event in Florida.

The 16-year-old, who won four professional tournaments while playing as an amateur earlier this year, sits nine shots back from leader Sandra Ga heading into tomorrow's third round at the Tiburon Golf Club.
