Guthrie shuts down A's in Royals' 5-0 win

Wyoming will examine bids for Sharp St.

First Posted: 8/18/2012 GREENSBORO, N.C&amp;#8212; Jimmy Walker left the booming, highlight-reel drives to his playing partner. A low score was good enough for him. 
Walker shot an 8-under 62 on Friday to take the lead at 12-under 128 after two rounds in the Wyndham Championship. 
Defending champion Webb Simpson (63) was one stroke back. First-round leader Carl Pettersson (68), Tim Clark (67), Sergio Garcia (63) and rookie Harris English (64) were at 10 under. 
Tim Herron matched the tournament record with a 61, but was still nine strokes back. 
Play was halted for 1 hour, 17 minutes late in the day when a system of thunderstorms passed through the central North Carolina Triad. 
Walker, who began the day four strokes back, had eight birdies in compiling one of the best two-day scores in event history. Only Pettersson at 125 in 2008 was better than Walker through 36 holes at Sedgefield Country Club. 
"I was playing with J.B. (Holmes), and he was bombing the driver everywhere, and I was just kind of bunting the 5-wood around and hitting good approach shots," Walker said. "It was pretty boring-looking golf &amp;#8212; not a lot of drivers, not a lot of 3-woods. There's a lot of 5-woods and some irons, and it's just kind of placement around the golf course." 
Walker hopes his strong round proves that he's getting back to the form from earlier this year, when the winless 33-year-old Texan finished in the top 10 in three of his first six tournaments. 
Things went south when he tore his left meniscus, so instead of going to the U.S. Open, he went to the doctor for a cortisone shot to reduce the swelling. 
Now that he can bend down and read greens again, he can do some damage with his putter. He used it just 26 times Friday, and didn't even need it on No. 2 because he chipped in from 50 feet.

ENDICOTT, N.Y. &amp;#8212; Bernhard Langer topped the leaderboard at 7 under when first-round play in the Dick's Sporting Goods Open was suspended because of rain. 
Coming off a victory two weeks ago in the 3M Championship in Blaine, Minn., Langer was facing an 8-foot birdie putt on the 16th hole when play was stopped at En-Joie Golf Course. 
Defending champion John Huston, Willie Wood and Chien Soon Lu were 5 under. Willie Wood, one of only 12 players to complete the round, shot a 67. Huston had three holes left, and Lu had nine to go.

CHERRY HILLS VILLAGE, Colo. &amp;#8212; Steven Fox beat top-ranked Chris Williams 4 and 2 in the U.S. Amateur quarterfinals at Cherry Hills. 
Fox, a senior at the University of Tennessee-Chattanooga from Hendersonville, Tenn., will play Brandon Hagy of Westlake Village, Calif., in the semifinals Saturday. Hagy, one of two players from the University of California to reach the semifinals, beat Taiwan's Cheng-Tsung Pan 4 and 3. 
Michael Weaver of Fresno, Calif., also a member of Cal's golf team, beat Ricardo Gouveia of Portugal 4 and 3. He'll meet University of Alabama freshman Justin Thomas of Goshen, Ky., in the other semifinal. Thomas edged Australian Oliver Goss 2-up.
