Overnight Masters co-leader Trevor Immelman gets his second round under way in the morning sun with four pars and a birdie

A birdie at the par-three 6th sees Brandt Snedeker move to five under before he takes the outright lead with another birdie at seven

But Immelman is going even better - he birdies the tough 17th and 18th to card a second successive 68 for eight under overall

Canada's Stephen Ames has a roller-coaster ride at Augusta National, carding six birdies and four bogeys for his round

Meanwhile, England's Paul Casey is going along nicely, holing a birdie putt on the par-three 3rd to move to two under

Steve Flesch is well placed after hitting Friday's best round of 67, including three birdies and an eagle at the 13th

Phil Mickelson goes on a birdie charge on day two, which is an ominous sign for the rest of the players - even Tiger Woods

South African Retief Goosen is starting to get into the groove, but his eagle at 13 is followed by a bogey

Lee Westwood looks to the heavens after a missed putt but worse is to follow on 13 - a double bogey seven

Tiger Woods is all smiles when he makes a birdie at the first - but the long-awaited Tiger charge has yet to happen. Yet...

Casey though manages to sign off his second round with birdies at 15 and 18 to push himself up to four under par

Jim Furyk sees his good progress checked with a painful double bogey at the final hole of the day

What of fellow Englishman Justin Rose? His bid to return to the top of the leaderboard is hit by a bogey on five

But Ian Poulter turns on the power, spanking his way to three birdies on the back nine to move to five under - tremendous golf

We have a new bookies' favourite - Mickelson takes the mantle from Woods and is pumped up after a birdie on 17 sets up a round of 68

Another former Masters champion makes a rally - Mike Weir shows that course knowledge can pay dividends

Not quite the case for 1992 supremo Fred Couples - he narrowly misses the first Masters cut of his career at four over

Gary Player finishes last but kisses the turf at the end of his 51st appearance and insists that he'll be back for a 52nd time

There's more pain for Tiger on day two, but he nails an excellent birdie at 17 and scrambles par at the last to end one under

No such luck for Rose who takes eight at 15 and tumbles to +2 - in stark contrast to fellow overnight leader Immelman who ends on -8
