Preview: The sparring and positioning is over and it's time for golf's heavyweights to go all out as the weekend's play begins at Augusta. Many of the world's top names remain in contention to be pulling on the Green Jacket come Sunday, but there is now little room for error with just 36 holes remaining.

Yesterday belonged to 52-year-old Fred Couples, who rolled back to the years to shoot a 67 and give himself a tie of the lead at five under.

I feel like I know every inch of the course. I've played 28 years here and today was really a magical day, said Couples afterward according to Reuters.

And the veteran who won his only major 20 years ago at Augusta will be teeing-off in the final paring alongside Jason Dufner.

Can I win? Couples repeated, according to ESPN. Yeah, I believe I can. Yes.

As for co-leader Dufner, the forgotten man sitting amongst the incredible performance of Couples and the host of stars just behind, well he has quite the story himself.

A 35-year-old journeyman pro, Dufner has never won a PGA Tour event. Yet he came agonizingly close to winning the last major. At the PGA Championship, incidentally also in Georgia, last August, the Cleveland-native had a five-stroke lead with four holes to play before losing in a playoff to Keegan Bradley.

And Dufner will have to put those memories out of his head if he is to stay ahead of the stacked cast of golf's finest that lie within striking distance.

Rory McIlroy, now considered by many to be the favorite to win a Green Jacket that so painfully eluded him a year ago, sits threateningly just one shot off the lead after a 69 on Friday.

I wouldn't say I'm in a position to win yet, he said, according to the Telegraph. I'm not leading, so that's a bit different to last year. I'm in the pack. But it's not a bad place to be.

Things could have looked very different at the top of the leaderboard had Lee Westwood not double-bogeyed 18 when looking set to maintain the outright lead he held after the first day. But, at four-under, the world No. 3 has the consistent driving and iron play to remain firmly in contention for his first major title.

As for Tiger Woods, well if he were anyone other than Tiger Woods he would have been completely ruled out already. The 14-time-major winner looked ill at ease in shooting a 75 on Friday and showed his frustration by kicking his club after a wayward tee-shot into the par-three 16th.

I have it in stretches, he said afterward, according to ESPN. I get into streaks where it's really good and then I lose it for a little bit. That's obviously very frustrating.''

It would take a dramatic and difficult to forsee turnaround for the 36-year-old to be in serious contention heading into the final day, but with Woods anything is possible.
