U.S. Ryder Cup captain Tom Lehman carded a 68 to join Paul Azinger, Jeff Sluman, Stewart Cink, Andrew Magee and Robert Gamez in a tie for fourth place at 5-under-par 135. Australia's Adam Scott was one shot further back at 4-under-par 136.
Amateur sensation Michelle Wie needed a strong round to make the 36-hole cut, but her shot at the weekend vanished at the par-4 sixth. Wie was scrambling at the sixth and things got worse on the green where she three-putted for a triple bogey.
Wie landed her approach inside 6 feet at the par-4 10th and converted the putt for her first birdie of the day. The 15-year-old, who missed the cut by a single stroke at this event last year, managed three bogeys over her next six holes, but closed her round with a birdie at the par-5 18th.
'Missing the cut by one last year, I thought, I made it so close, I kind of took it for granted that I was going to play better,' she said. 'But I learned a lot of things this week, more from last year I think. I think when you play bad, you learn a lot more.'
Wie posted a 74 on Friday to finish at 9-over-par 149. A total of 78 players survived the cut at 2-over-par 142.
Maruyama was one shot back to start the day at Waialae Country Club and rolled in a long putt at the par-4 fifth for his first birdie of the day. Maruyama then hit his second shot to 5 feet for a birdie at the eighth and chipped in for an eagle at the par-5 ninth to make the turn at 7 under.
He kept on rolling with a birdie at the par-4 10th and played his approach inside 10 feet for a birdie at the par-4 15th.
'It's a little bit hard to read the greens here, but I'm making some good putts,' said Maruyama. 'It's been very steady.'
Maruyama missed the fairway en route to a bogey at the very next hole, but parred his way in to secure the outright lead heading into the weekend.
'It's really difficult to read the wind,' he said. 'It's not as strong as yesterday, but it's coming from a little bit different direction. So it's very hard to play in this wind.'
Rose jumped out of the gate with a birdie at the first and ran off three consecutive birdies starting at the fifth to get to minus-7. That run came to an end with a bogey at the eighth but Rose recovered with a 14-foot birdie putt at the 15th.
The 24-year-old faltered with a bogey at the 16th but knocked his tee shot within 6 feet of the hole for a birdie at the par-3 17th to cap off a round of 66.
'I think the key for me this year is to focus on the process of putting little building blocks in place, and that will enable me to get the final result,' said Rose. 'That's kind of what I'm working on.'
Quigley struggled early with a bogey at the opening hole but he got that shot back with a birdie at the third. Quigley then birdied the sixth and holed out from a greenside bunker for a birdie at the eighth.
At the par-5 ninth, Quigley played his second shot to 5 feet and sank the eagle putt to reach 8 under around the turn. He held steady with a string of pars on the inward half but a bogey at the 16th left him one shot behind Maruyama.
'It was just a good day, a patient day,' said Quigley, who posted a 67. 'Had a nice stretch there in the middle, and maybe got a little ahead of myself the back nine thinking about shooting a real low score and made a bunch of pars.'
Top-ranked Vijay Singh finished alongside Tom Byrum, D.J. Trahan and Jason Allred at 3-under-par 137. Two-time defending champion Ernie Els followed in a group at 2-under-par 138.
