Rose surged to seven under alongside American Brett Quigley with Japan's Maruyama out in front after a 65 at the Waialae Country Club in Honolulu.

World number one Vijay Singh edged to three under with a 68, while South African Ernie Els was a shot behind.

Hawaiian teenager Michelle Wie missed the cut after a 74 for nine-over-par.

"There are several things I've made up my mind to do in 2005 and I did a couple of them today," said Rose.

"Last year I would have been exasperated with myself for missing the fairway off the tee and I would then have tried to force my second on to the green.

I was pulling my pants up as I ran down the corridor Justin Rose

"Today was a first step in staying patient and taking my medicine."

England's Rose, 24, was nearly disqualified on day one for missing his tee time after an unexpected early morning drop-out gave the first reserve a slot.

"I was pulling my pants up as I ran down the corridor," said Rose.

But he fared better than his more illustrious Ryder Cup-winning countrymen.

Ian Poulter carded a second-round 74 for eight over while Paul Casey was one shot worse after a 75.

But Greg Owen, sixth at the US Tour qualifying school, made the cut on two over after a 73.

I want another chance because I know I can do better than this Michelle Wie

The 15-year-old Wie, who missed the cut by one shot last year, took three putts from eight feet for a triple bogey on her sixth hole and could never recover.

"I think I tried too hard," said the amateur.

"After missing the cut by one last year, I think I took for granted that I was going to play better. Last year, everything went too easily."

She was trying to become the first female in 60 years to make the cut on the PGA Tour.

She will return to professional ranks next month on the LPGA Tour for the SBS Open in Hawaii.

And two-time defending Sony Open champion Els insisted she deserved her place in the event.

"That is not throwing an invite away," he said of the sponsor's exemption Wie received.

"It's phenomenal what she is doing for the game."
