Golf: Lydia Ko on track at the halfway stage of Tournament of Champions in Florida.

Lydia Ko has continued her hot start to 2019 in the second round of the Tournament of Champions in Florida.

The 21-year-old had five birdies and two bogeys to finish with a three under par 68 - good enough for a share of second place with Eun-Hee Ji and world number one Ariya Jutanugarn, and just two shots behind leader Brooke Henderson.

The former world number one is chasing her 16th win on the LPGA Tour in the Tournament of Champions, which is in its first year.

England's Georgia Hall had the best round of the day, shooting a five under 66 to sit in a tie for 15th.
