A huge cheer from the galleries as Justin Rose chips in for birdie on nine. A pump of the fist from Rose as he moves back to level par. Maybe the spark he needed? Adam Scott misses his birdie putt at the same hole to stay on three under.

Another dropped shot for George Coetzee on 17 as he falls back to four under, two shots off the McIlroy's lead.

The most challenging par three on the course. Normally played into a crosswind, it is surrounded by deep bunkers. The long, narrow green slopes from back to front.

Phil Mickelson gives himself a chance of making an unlikely par on 10, despite finding trouble off the tee. 10 foot putt to stay at one over.

A good second round from American D.A. Points, whose three-under-par round today moves him level par for the championship.

"People are making strides forward and then going just as fast backwards. It's that type of course. It was hard enough yesterday in a kinder breeze."

George Coetzee is in trouble again. After dropping a shot to lose the joint lead on the last hole, he finds the deep, deep rough with his tee shot and is unable to find the fairway with his second. A real shame for the South African, currently on five under.

Phil Mickelson is falling the wrong side of fine margins. Remember he came within a whisker of following up his eagle on five with a birdie on seven but for a missed putt.

Well after bogey on nine, he has just pumped his tee shot on 10 into bushes. 'Lefty' plays a provisional. If he is capable of locating his original ball he must be brilliant at finding the TV remote.

One over for the day, he could be back to where he started on plus two shortly.

American Jordan Spieth:, external Day 2 out here looking to be more challenging with the wind. Gotta be low and straight all day today.

Spieth tees off alongside Rory McIlroy at 14:27 BST and harbours hopes of a first major himself. He is currently one under par.

Challenges, challenges... Phil Mickelson and Bubba Watson take advice from their caddies as they assess the dangers that lurk ahead.

Thailand's Thongchai Jaidee is doing very nicely with a birdie on 11 taking him to three under for the day and the championship.

No sign of any caution from co-leader George Coetzee as he pushes a a putt for birdie a few feet past the hole. He isn't the co-leader any more as he misses the putt for par to return to five under.

Our co-leader George Coetzee is ranked 72 in the world and has a best major finish of 15th in the 2011 Open.

He has one win on the European Tour which arrived in February and earned him his place at the Open.

Should he finish where he is now, it will be his biggest pay day since turning professional in 2007 by a country mile.

So close for Phil Mickelson. His 15 footer for birdie on nine just moves away at the last moment as he stays at one over.

Tommy Morris Junior is the youngest player to have ever played at The Open, competing in 1865 aged 14 years, four months and 25 days. His father, Tom Morris Senior, is the oldest player ever, playing in 1896 aged 74 years, 11 months and 24 days.

The Open moments floodgates are officially... open. No sooner did BBC Sport's Dan Walker ask you for your best ones and there are suddenly plenty on offer:

Danny Barnes:, external I was at Royal Liverpool GC when Seve Ballesteros made his last birdie at an Open Championship and maybe his last major.

Eugie B:, external 72nd hole at Carnoustie '07 when Padraig's son ran on to the green. It lifted PH's spirits instantly. Just a lovely moment.

That moment triggered one of the greatest Open quotes from Harrington junior: "Daddy, can we put ladybirds in it (the trophy)?"

We'll know where to find you then, Matt.

The big hitters, and brave, will fancy their chances of picking up scores here by driving to the corner of the dog-leg, over the waiting gorse, and going for the green in two. This hole yielded 23 eagles and 205 birdies during the 2006 Open. Dangerous bunkers lie in wait though as does a heavily contoured green.

George Coetzee's place at the top of the leaderboard has been heavily influenced by his deadly putting. He is through 15 holes today, 33 in total and has one-putted on 19 of them.

Only five players have broken par on the outward nine so far today. This is a test today. Justin Rose, as if to prove that, drops a shot on seven to move to one over.

Mickelson drops to one over after a bogey at the eight. Brilliant par putt from Adam Scott on seven to stay at three under.
