DiMarco ended one shot outside a record rookie opening round score

"I don't think the spotlight's on me because nobody expects me to win but me," said DiMarco, invited to Augusta National bu virtue of his 19th place finish on last year's USPGA Tour money list.

For much of the day the American amateur champion James Driscoll led the chasing pack on a leaderboard peppered by American names.

But it was more recognised names on the professional tour who finally began to chip away at DiMarco's imposing lead.

Mickelson battled his way into contention on the back nine and in the process stated his intentions for the tournament.

The left-hander hit four successive birdies as he built a platform from which he will be looking to win his first Major.

At four-under Jimenez was the top European

For much of the day the Spanish triumvirate of Jimenez, Jose Maria Olazabal and Sergio Garcia battled valiantly against an American monopoly at the top of the leaderboard.

But as the more celebrated pair fell by the wayside, Olazabal ended with a bogey to join Garcia on two-under, Jimenez carded his best round at Augusta finishing three shots off the lead.

Garcia and Olazabal are among a host of names, along with Denmark's Thomas Bjorn, five shots off the lead.

However it is the name of Woods at two-under-par that everyone at Augusta, from DiMarco down, will be watching with interest on day two.

Woods in turn will be looking to throw off the frustration and torpor of his opening day.

Woods endured some frustrating moments

From his opening shot which arrowed off the fairway, to the final green when a birdie putt drifted wide, Woods never looked at home with his game.

"I liked my iron shots but I didn't putt as well as I can do," Woods reflected.

"Overall I am very pleased with the way I played and you can't be unhappy when you shoot a red number," he added.
