DeLaet leads by 2 at Waialae

Graham DeLaet missed most of last season with a herniated disc in his back.

He is playing this season on a major medical extension and has to earn over $650,000 this season in order to keep his tour card for next year.

So far, so good.

DeLaet fired a seven-under 63 on Thursday to grab a two-stroke lead after the opening round of the Sony Open in Hawaii at Waialae Country Club.

The Canadian is searching for his first win on the PGA Tour, though he has won three times on the Canadian Tour.

K.J. Choi, the 2008 champion, and Carl Pettersson are tied for second place at minus-five. They were joined there by Kyle Reifers, who made it back to the PGA Tour this year for the first time since 2007.

Last week's winner Steve Stricker and Webb Simpson, who tied for third behind Stricker at Kapalua, both carded four-under 66s and they headline a group of 12 players that share fifth place.

Through seven holes, DeLaet didn't look like he would be the first-round leader. He birdied the first, but gave that stroke back when he tripped to a bogey on the fourth.

After three more pars, DeLaet caught fire. He rolled in an 11-foot birdie try on No. 8, then chipped in for eagle on the par-five ninth.

DeLaet poured in a 37-footer for birdie at 10 to move to four-under. He kept going with a birdie at the 12th.

The 29-year-old parred his next four holes. At the par-three 17th, DeLaet dropped his tee shot within eight feet and he converted that putt for birdie. He played his third to the par-five 18th to about three feet. DeLaet sank that for a closing birdie and a two-stroke lead.

"It's definitely exciting to be back on the golf course," admitted DeLaet. "Great way to start the year. Just being in Hawaii, period, is a great way to start the year and to come out and fire a nice round in the opening round was great."

Last year, DeLaet only played in four events (two PGA, two Nationwide Tour) due to a herniated disc. He had surgery early last year, but admitted it was probably November before he could take a full swing with his driver.

"I'm still progressing, I wouldn't say I'm 100 percent, but better than even before the real bad injury," DeLaet said. "I'm just so excited to be back out. The one thing with the injury, when you're out here on tour, I had a good season my rookie campaign (2010), and then it was all basically just taken away. And I realize now how fortunate we are to be playing golf for a living and you know, my whole attitude is definitely better."

Choi played the back nine first Thursday and had four birdies and a lone bogey on his opening nine. He parred the first six holes of the front side, then birdied two of the last three holes to share second.

Pettersson had a bogey-free round with three birdies on the front and two more around the turn.

Reifers started on No. 10 with a par. He birdied three of the next four holes, but his non-birdie in that span was a bogey at the 13th. Reifers turned at three-under after a birdie on 17. He had three more birdies and a bogey on the front nine.

NOTES: Last year's winner Mark Wilson struggled to a three-over 73, which left him tied for 121st place...Sixty-three of the 144 players in the field broke par in the opening round.
