"Suzann Pettersen has played a number of quality iron shots and has not had the results she deserves from them."
Chinese Taipei's Teresa Lu shared the over night lead with Ko Jin-young, but dropped three shots in the first two holes. A five-foot birdie change goes begging on the fifth, before Ko holes out for par. The leader is wrapping herself up a pink jacket. Furry hood, East 17-style.
Ko Jin-young is taking her time on the fifth green, circling her ball with suspicion. Just on the fringe, up then down, right to left. Just short, but good for a par.
Mel Reid, pink top and baggy grey trousers, doesn't like her approach to the par-five seventh. She's dropped her club, in fact. I think she got as much of the ground as she did the ball. It's barely gone anywhere. Extraordinary.

"Inbee Park is a very serene player. She never seems to do anything exciting and then you add it all up and she makes a 68. It is quite remarkable."
Good news for a Brit
Now then, Amy Boulden. The 22-year-old from Wales has birdied the par-five seventh, her third of the day, to go to four under, four off the lead.
There's two bogeys in her round, too. Cut the errors and she might contend.
Excellent flotilla of ducks bob up and down on the sea, carried along by the waves. They look as calm as Ko Jin-young.
There's been lots of chat about slow play throughout this tournament, and, at the moment, it remains sedate. Settle in.
Hmmm, more trouble for Inbee Park, another shot gone on the fifth. From seven under, she's slipped to five under in the blink of an eye.

"Ko Jin-young looks very calm for a newcomer to the game. Very relaxed. Let's see how she is in a couple of hours."
Leader Ko Jin-young is not only playing in her first major, but also her first links tournament and is even on her first trip to Scotland. In a stripy jumper, mainly of orange, and maroon trousers, she's steadily playing par golf at the moment and will look for more of the same with a short putt on the fourth. In it goes. Very calm.
If Pettersen is to carry the European charge, she does so in the hunt for a third major. Dressed in a peach gillet and matching trainers, she's off down the fifth.

"Pettersen's putting hasn't been great, especially yesterday. If she wants to win this Championship she needs to get her putting going."
Hmmm, it already looks like this leaderboard will be hard to keep up with. Suzann Pettersen, joint-leader for a short while, has bogeyed the par-three fourth. She's back to seven under, leaving Ko Jin-young alone at eights.
As the sea laps the shore, it's tricky on the coast.
Good news for a Brit
Ah, Melissa Reid! Our first sight of the British challenge today and it's a belter, draining a long one of the fifth for her first birdie of the day. Five under, three of the lead.
Her playing partner Lydio Ko has holed that par putt to stay at six under. Eight players are within three of the lead.

"The bird may have damaged that ball. If that is the case there'll be a quick change. No dramas."
Hello, what's this? A ball just off the green, second cut. Is that a crow having a good peck at it? I think it belongs to American Katie Burnett, way down the list on five over. That won't help.
Lydia Ko, the whizzkid world number two from New Zealand, is in a spot of bother on the fifth.
All in black (obviously, for a Kiwi), she's gone through the back of the green and is some of the long stuff. Ah, that's nice. Bump into the fringe, leaving four feet for par.

"Some of the leaders are struggling early on in the piece."
Conditions at Turnberry are, well, atrocious. Windier than a scrum after beans on toast, the odd drop of rain too.
Ooohhh, bad miss from Park on the par-three fourth, she's dropped back to six under.
