putts

The 21-year-old, playing in her second tournament since turning professional, made lengthy birdie putts at the first and sixth holes as she reached the turn in level par.

No putts, no wedges and no water hazards.

A vigorous pump of the fist signalled his pleasure at dropping one of several par-saving putts on his way to glory.

McIlroy had provided the early fireworks in his native Northern Ireland with three birdies in his first four holes, while England's Matt Fitzpatrick and Robert MacIntyre of Scotland knocked in eagle putts.

But it was a switch from his trusted blade to a mallet putter "to help him with lining up putts" that really sparked a change in fortunes.
