Suddenly Matsuyama is the man to beat.

Three in a row!

Hideki Matsuyama is the hottest man on the course right now. He just doesn't look like missing on the greens. Another putt from eight foot rolled in and he's just two off the lead.

This leaderboard is starting to take shape. Kevin Kisner isn't looking as secure as he did an hour ago with Day, Matsuyama and Oosthuizen closing the gap.

Chris Stroud is the latest to make his move with back-to-back birdies on 14 and 15.

Left, right, left, right. Jordan Spieth was everywhere on that hole...

Garcia taps in for his first birdie of the day to get back to six over, which is still many for the projected cut at plus four. A tap in birdie also for Koepka, who is back to two under. Spieth has to hole from five feet to drop only one shot. How long did that hole take?

More perils in the pine straw for Spieth and he is still in there at the 10th after his third shot hits a branch of a tree at the par five.

This round is getting better and better for Hideki Matsuyama!

He's closed the gap to Kevin Kisner to just three shots with another birdie. Too early to suggest we could see Japan's first major winner this weekend?

Spieth finally hits, but it has gone left...into more pine straw.

A little further back it's another birdie for former world number one Day, who has picked up four shots in the last three holes. Only four back now.

Spieth is moving the spectators around, let's hope this shot isn't going to take 45 minutes like at The Open. There is no equipment truck in his way this time, only a mass of pine straw.

"How could I make a mistake here?" he asks a marshal. "What can't I do?" He is told he cannot move anything that is growing or imbedded into the ground.

"Thank you, I appreciate that." Nice young man. But very, very thorough. After scraping a load of loose pine needles away, he drops his ball. He hasn't hit it yet though, now we have to decide what sort of shot to play.

South African Louis Oosthuizen is going along nicely under the radar here. The 2010 Open winner has got himself to -4 with three birdies in his seven holes so far. He has another chance on the 17th after a lovely tee shot but it's not to be. Still, he's in second four off the lead.

As is Hideki Matsuyama! He confidently rolls in a 10 footer and joins Oosthuizen at four under.

Are one of these two going to be the ones to challenge Kisner over the weekend?

Security staff need to cool off somehow...

Another booming drive from Day, no relation to the late Sir Robin, or Darren, or Kevin. Are there any others? It has gone 133 feet up in the air and sailing down the middle. Playing partner Johnson's drive drifts right, but finds its way through some thickset spectators in three quarter length shorts and it meanders along a cart path.

It's all falling apart for Thorbjorn Olesen. It's not nice to watch. After that seven on the previous hole, he has hit his tee shot into the trees on 16. He follows that up with a second shot that skews way left, takes a couple of bounces and bobs down into the water. More shots are going to be dropped here I fear.

Eagle and birdie will smarten up a scorecard and Day moves to three under, five off the lead.

Fresh from that eagle at the last, Day drives to within a couple of yards of the putting surface at the 350-yard par four eighth and his chip trickles just past the flag. Five feet left for a birdie.

Not too many eccentric shirt-trouser combos so far today but Bubba Watson's socks are "on point" in the Americans own words...
