Pebble Beach, CA (SportsNetwork.com) - Andrew Loupe fired an 8-under 63 on Thursday and took a 2-shot lead to the clubhouse with the first round of the Pebble Beach National Pro-Am suspended due to darkness.

Loupe played his opening round at Monterey Peninsula's Shore Course. He will rotate to Spyglass Glass and Pebble Beach for the next two rounds, before Pebble Beach hosts the final round.

The PGA Tour rookie is making his sixth start in the new wrap-around season, and this is the second time in 12 rounds that he has broken par. He opened the Humana Challenge with a 67, but missed the cut as he did in all five of his starts so far.

Jimmy Walker opened with a 6-under 66 at Pebble Beach. He was joined at minus-6 by Stuart Appleby, Scott Gardiner, Jim Renner and Richard H. Lee, who all played at Monterey in the first round.

Jordan Spieth carded a 67 at Spyglass, while Robert Streb posted his 67 at Pebble Beach. They share seventh place with Brian Harman, 2006 runner-up Rory Sabbatini, Dicky Pride, Brian Davis, four-time winner Phil Mickelson, 2011 champ D.A. Points and Tim Wilkinson, who all still have holes to play in their first rounds.

There was a two-hour, 51-minute weather delay earlier Thursday that pushed action back. The first round will resume at 10:45 a.m. ET on Friday, while the start of the second round was pushed to noon.

Loupe started his first round with a birdie on the first at Monterey. He ran off four straight pars from the second before converting his next birdie at the par-5 sixth.

The 25-year-old converted a birdie effort on No. 8 and parred the ninth to make the turn at minus-3.

Loupe birdied the 10th and 12th, both par-5s, to move to 5-under. After a par on No. 13, he birdied three of the next four holes to jump to minus-8. He parred the last to end there.

"I just keep telling myself, you're supposed to be here, you're going to play good, just keep playing. And this is just one round, guys, you know, but I feel good," Loupe stated.

Walker had three birdies on both the front and back nines at Pebble Beach for his opening 66. Appleby and Renner also had three birdies on both sides at Monterey.

Gardiner had three birdies on the front nine to go with four birdies and a bogey around the turn. Lee stumbled to a bogey on the second, but came back with six birdies in an eight-hole span from the sixth. He birdied the par-5 16th to gain a share of second place.

NOTES: Loupe's best finishes on the Web.com Tour last year were a share of fifth at the South Georgia Classic and a tie for sixth at the Web.com Tour Championship ... His 63 matched his low round as a professional as he also shot 63 last year at the Cox Classic on the Web.com Tour ... Defending champion Brandt Snedeker and three birdies and three bogeys in his round of 72 at Spyglass. One of the players he is tied for 97th with at even-par is Bo Van Pelt, who carded 18 pars in round one at Pebble Beach.
