GREENSBORO, N.C. – 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 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 area.

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 – 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.”

LPGA: In North Plains, Ore., Mika Miyazato and Sydnee Michaels shot 7-under 65 in 100-degree heat to share the first-round lead in the Safeway Classic.

Cristie Kerr, Inbee Park and Pornanong Phatlum were a stroke back. So Yeon Ryu was two shots behind at 67 along with Brittany Lincicome, Alison Walshe and Jee Young Lee.

Former Fort Wayne resident Amanda Blumenherst was tied for 79th at 2-over 74.

US AMATEUR: In Cherry Hills Village, Colo., 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 today. Hagy, one of two players from the University of California to reach the semifinals, beat Taiwan’s Cheng-Tsung Pan 4 and 3.

CHAMPIONS: In Endicott, N.Y., Bernhard Langer topped the leader board at 7 under when first-round play in the Dick’s Sporting Goods Open was suspended because of rain.

Langer was facing an 8-foot birdie putt on the 16th hole when play was stopped at En-Joie Golf Course.
