Graeme McDowell’s lead under pressure at HSBC Champions

The momentum at the HSBC Champions belongs to U.S. Open champion Martin Kaymer and Masters champion Bubba Watson.

The lead at Shanghai’s Sheshan International still belongs to Graeme McDowell.

And the mystery is Hiroshi Iwata, the journeyman from Japan and a surprise guest among major champions atop the leaderboard Saturday in the final World Golf Championship of the year.

McDowell ducked in from the cold, gray afternoon at Sheshan International and wrapped his hand around a warm cup of coffee. He did not look the least bit worried after watching a four-shot lead dwindle to one over the final eight holes.

“Let’s be honest. Yes, I had a three-shot lead overnight and it’s only one now,” McDowell said after his 1-under 71. “But I’ll take this position any week that you offer it to me — a one-shot lead going into the last round on a golf course that I enjoy. Looking forward to the opportunity tomorrow.”

McDowell was at 11-under 205, one shot ahead of Iwata, who made a long, curling birdie putt on the par-5 18th for a 68, and two shots ahead of Kaymer and Watson.

Kaymer zoomed into contention with seven birdies in a round of 66 and will play in the last group. Watson off four birdies over the last five holes for a 69 and joined Kaymer at 9-under 207.

Rickie Fowler recovered from a double bogey in the water on No. 9 for a 69. He was only three behind, along with Tim Clark of South Africa, who also had a 69. Ian Poulter had a cold putter and a 72 and was four shots behind with Thorbjorn Olesen of Denmark, who had a 69.

John Rollins takes charge at Sanderson Farms Championship

John Rollins took a two-stroke lead in the Sanderson Farms Championship, birdieing two of the final five holes for a 4-under 68.

Tied with David Toms for the second-round lead, Rollins had a three-round total of 14-under 202. He won the last of his three PGA Tour titles in 2009.

William McGirt was second after a 66, matching the best round of the day. Jason Bohn and Lucas Glover were third at 11 under. Bohn also shot 66, and Glover had a 67.

Toms and Canada’s Nick Taylor were 10 under. Toms had a 72, and Taylor shot 70. After two bogey-free rounds, Toms bogeyed Nos. 4-6. He birdied Nos. 7, 10 and 18, holing a 31-footer on the final hole.

Laura Davies leads at Mizuno Classic

Laura Davies remained in contention to become the oldest winner in LPGA Tour history, shooting a 5-under 67 for a share of the second-round lead in the Mizuno Classic.

The 51-year-old English player had seven birdies and two bogeys at Kintetsu Kashikojima to match Japan’s Ai Suzuki and South Korea’s Ilhee Lee at 9-under 135. Suzuki had a 64, and Lee shot 66.

Davies won the last of her 21 LPGA Tour titles in 2001. She also has 45 victories on the Ladies European Tour, the most recent in the 2010 Indian Women’s Open.

Beth Daniel is the oldest LPGA Tour champion, winning the 2003 Canadian Women’s Open at 46.
