Ian Poulter responds to Spieth's tee shot at the fourth with a beaut of his own - he's a couple of feet further away but straight down the slope rather than across it.
Rory McIlroy is on another level. He hits the most glorious bunker shot into the heart of the green under complete control the whole way. Just brilliant.
Mickelson's levelled his bunker shot into the greenside gallery. That means he holes the next one, usually.
Keegan Bradley playing from ANOTHER bunker. As is Mickelson. The match of the morning is turning into beach golf.
Jordan Spieth reapplies the pressure to Poulter-Gallacher, hitting a cracking tee shot to six feet at the par-3 fourth. Rookie nerves? Whaddeva.
It's dead centre from Stenson but he leaves it short. The greens still haven't quickened up yet. With so many players so used to American greens, this is going to be a morning of adjustment. Bear in mind that the practice times were mid-morning - this is the earliest people have played this week.
Justin Rose, fresh from birdieing the fourth, double bogeys the fifth. Regardless, Henrik Stenson has a putt for the hole.
And he does it! That keeps the deficit at one for Gallacher and Poulter versus the two rookies, Spieth and Reed.
Now Poulter needs to spark something in his match. He has a 10-footer for a halve.
Another wonderful putt at the par-3 fourth - Martin Kaymer puts him and Bjorn 3-up after four against Fowler and Walker. Kaymer is playing the best golf of anyone on the course, no question.
Perhaps - they've put it on the back level. Expect it to be at the front on Sunday for added drama.
It's a deceptively tricky green, but it's fascinating that every player is missing it on the low side.
And he's shaved the edge of the cup! Oh that was close. The last match remains all square.
Which leaves Keegan Bradley with a putt to win the hole, having been in the worst position off the tee. Matchplay is so great!
Also misses on the low side, just as McIlroy's did. He really should have learned from his partner's putt.
McIlroy misjudges his birdie putt as well, it never really being on the right line despite a decent pace. Now Garcia for his birdie...
He's putting with two gloves on. Really, it's not that cold!
Mickelson lining up his very tricky birdie putt at the second. It's about 25 feet, uphill then downdale and with a good deal of break. And that is not even close. A shocker from Phil.
Martin Kaymer hits a doozy at the par-3 fourth. Genuinely haven't seen him hit shots like this since June and the US Open.
Phil Mickelson is certainly carrying Bradley so far - Bubba and Webb are kind of dragging each other down.
Mickelson's third is into the heart of the second green - he'll have a putt for birdie but nobody has really seized the initiative on that particular hole.
Thomas Bjorn drains a beaut at the third to halve that hole and remain 2-up. Europe 2-up in the first two matches and putting wonderfully.
Justin Rose holes his birdie putt at the fourth. They are 2-up on Watson and Simpson.
Keegan Bradley has stymied himself a bit at the second - his tee shot has found the bunker (that's two-for-two on that front) and he's had to pitch out. McIlroy is on the grassy verge of the same bunker and also has to lay up. His lay-ups are a bit different to a normal human being's - that's gone absolutely miles from a half-swing.
Indeed. However, remember that a lot of Poulter's big Ryder Cup moments have come from him digging himself out of a hole or being up against it. The latter part has to have this first part...
Stephen Gallacher is trying to bail out Ian Poulter at the moment - that's not a typo. He has a putt for a halve - and he's holed it! They remain 1-down to the pair of rookies, Reed and Spieth.
Poulter has a chip from the fringe at the second for birdie, and it's a shocker. He's not brought his A-game so far. More like his Z-game.
Justin Rose stiffs his tee shot at the par-3 fourth, Ian Poulter duffs a bunker shot at the second, Bubba underclubs at the fourth.
In short, it's all happening.
What a putt! Rory McIlroy holes for the halve at the first and gives it a very, very determined fist pump. That's the best putt of the morning, after the best drive of the morning. Is this Rory's crowning glory this weekend?
Bubba has done the same again at the third. Not hard enough, finishes just next to the cup.
You need to hit it firm and without as much break as it seems. Hit it soft, it will fall off line.
Going back to that putting comment from Andrew - it's a very different beast putting on Scottish greens first thing in the morning. Take it from a Scot!
Europe up in the first two matches, USA up in the third, USA likely to go ahead in the fourth. It's a bit close, isn't it?
Bjorn to win the second hole - and he nails it. Two holes played, two holes won by Kaymer and Bjorn against Walker and Fowler.
Decent effort from McIlroy, but Mickelson is three times closer and in the driving seat.
