FARMINGDALE, N.Y. (AP) - A common phrase this year - "Tiger's back" - took on a new meaning Friday at The Barclays.
Woods felt a twinge in his lower back when he awoke and felt pain throughout the second round at Bethpage Black. He overcame a bogey-bogey start, struggled in the simple task of retrieving the ball from the cup and stayed well within range of Nick Watney and the resurgent Sergio Garcia, who shared the lead.
"Must have slept funny on it," Woods said. "Soft beds at the hotel, and woke up this morning with it stiff. As I warmed up, it got progressively worse, and then you saw what happened on the golf course. It hurt all day."
He managed a 2-under 69, a good effort in the afternoon on greens that tend to get crusty.
More impressive were Garcia and Watney, also playing in the afternoon as they worked their way up the leaderboard. Garcia, who ended a four-year drought on the PGA Tour last week by winning the Wyndham Championship, made bogey on the third hole with what he called his worst swing of the week and atoned for that with a tee shot on the par-5 fourth that restored his momentum and sent him to a 68.
Watney went eagle-birdie on the par 5s on the front nine and then survived a roller coaster of birdies and bogeys on the back nine that gave him a 69.
They were at 8-under 134.
Vijay Singh, who last won a PGA Tour event in 2008 when he captured the opening two playoff events and sailed to the FedEx Cup title, played bogey-free for a 67 and was one shot out of the lead, along with Bob Estes, who had a 66. John Senden (68) and Pat Perez (70) were another stroke back.
CANADIAN WOMEN'S OPEN
COQUITLAM, British Columbia (AP) - Teen star Lydia Ko shot her second straight 4-under 68 for a share of the lead with Chella Choi in the Canadian Women's Open.
Ko, the 15-year-old South Korean-born New Zealander who won the U.S. Women's Amateur two weeks ago, birdied four of the last seven holes in a bogey-free round to match Choi at 8 under. In January, Ko won the New South Wales Open in Australia at 14 to become the youngest player to win a professional tour event.
The 22-year-old Choi, from South Korea, followed her opening 72 with a 64 at The Vancouver Golf Club.
U.S. Women's Open champion Na Yeon Choi, Angela Stanford, Moira Dunn and Inbee Park were tied for third at 5 under. Na Yeon Choi had a 72, Stanford and Dunn shot 70, and Park 71.
Top-ranked Yani Tseng, the first-round leader after a 66, had a 75 to drop nine shots back. Michelle Wie, the 2010 champion at St. Charles in Winnipeg, Manitoba, missed the cut with rounds of 74 and 76.
SNOQUALMIE, Wash. (AP) - Defending champion Mark Calcavecchia eagled the par-5 eighth hole and finished with a 7-under 65 to take the first-round lead in the Boeing Classic.
Calcavecchia, a playoff winner over Russ Cochran last year at TPC Snoqualmie Ridge for his first Champions Tour title, made a 20-foot putt on No. 8 after his 4-iron approach sailed over the flag.
Calcavecchia won the Montreal Championship in June for his second victory on the 50-and-over tour.
Steve Pate, Jeff Sluman, Joe Don Blake, Eduardo Romero and Kirk Triplett were tied for second at 68.
Fred Couples withdrew because of back problems on the first hole. The Seattle player won the Mississippi Gulf Resort Classic in March and Senior British Open last month.
JOHNNIE WALKER CHAMPIONSHIP
GLENEAGLES, Scotland (AP) - Englishmen Mark Foster and Richard Finch shared the lead at the midway point of the Johnnie Walker Championship at Gleneagles.
Foster, who lost out in a five-man playoff last year, shot a 4-under 68, and Finch had a 67 to finish at 8-under 136. Scotland's Paul Lawrie eagled his ninth hole en route to a 67 for a share of third place at 7 under with Australia's Brett Rumford (70).
Belgium's Nicolas Colsaerts kept alive his chance of automatically qualifying for the European Ryder Cup, shooting a 70 to finish at 5 under. He needs to finish first or second to qualify automatically.
