Ko keeps cool in making history

Teenager becomes golf's all-time youngest No 1

With a notable double prize not only within reach, but practically in her grip, New Zealand teenager Lydia Ko had to settle for half of the spoils on Saturday - though it still represented a significant piece of golf history.

After reclaiming the lead late in the final round, the 17-year-old Ko double-bogeyed the 71st hole in the inaugural Coates Golf Championship to lose by a shot to Choi Na-yeon.
