(MENAFN -Arab News) PEBBLE BEACH, California: Texan pair Jimmy Walker and Jordan Spieth played through the wind and the rain to take a share of the lead after Friday's second round of the AT&T Pebble Beach National Pro-Am.Walker made some tough par saves and wound up bogey-free at Spyglass Hill with a 3-under 69 while 20-year-old Spieth was down the coast at Monterey Peninsula, where he called the birdie on his final hole the best of his life.They were one shot to par ahead of Hunter Mahan.The slight advantage would go to Walker, who was at 9-under 135. Already a two-time winner this season, Walker next goes over to Monterey Peninsula, the easiest of the three courses in the rotation. Spieth was at 9-under 134 and headed to Pebble Beach, which can be difficult in more forecast wintry weather.Along with a three-club wind on the exposed sections of all three courses, steady rain began coming down sideways toward the end of the second round. There was about a 75 percent chance for more rain Saturday.Spieth was happy to at least get Spyglass out of the way already, having opened with a 67 on Thursday."Today was very difficult," Spieth said. "We started out in the rain and wind, and we finished in rainier and windier," he said.Mahan had a 68 at Spyglass Hill, with half of his six birdies on the par 5s. He was at 8-under 136."Coming up these last few holes are tough," Mahan said. "They're uphill, they got the wind, it's getting cold, raining. You just don't want to throw away shots. Because this can be a long week, and it could be mentally more grinding than anything."Andrew Loupe, who has missed every cut in his rookie season so far, followed his 63 at Monterey Peninsula with a 73 at Pebble Beach. That wasn't too bad, for Pebble Beach was playing to an average of 74.1, about 2- strokes more difficult than Thursday. He was at 7-under 136 and plays Spyglass on Saturday.Phil Mickelson finished off his 66 at Monterey on Friday morning, holing some good birdies, but missing plenty of short ones. He switched from a conventional grip to the claw during his round, searching for answers. A three-putt bogey on the 18th at Pebble gave him a 73. He was at 4-under 139, still very much in the game."Tee to green, I'm playing very well, but I haven't putted this poorly in a year," he said. "For the way I'm hitting it, it's a little disappointing because I should have a really good opportunity. And I'll have to turn it around. It's not too late, but I've got to get it turned around here."David Duval showed some promise in his first PGA Tour event of the year with a 68 at Spyglass, a course that in the past has given him problems. He was at 4-under 140."What's the forecast tomorrow? More of this? Cool," Mickelson said with a deadpan delivery. "We've had a great run of weather ... so we certainly can't complain. It's sometimes a fun challenge to play out here as the reigning Scottish and British Open champion. I don't really mind the elements, but I do have to get this putter worked out."It already was a challenge for so many others. John Daly shot 79 at Monterey Peninsula. Four players failed to break 80. Two-time champion Dustin Johnson fell back with a 73 at Monterey. Jason Day of Australia shot 77 at Pebble Beach with one birdie.
