<p>Woods, who led by one after an opening 67, burst out of a four-way tie on the front nine with back-to-back birdies from the sixth and pulled away from a late challenge by Briton Ross Fisher with three birdies to post 70 for a seven-under total of 137. <br /><br />Five players were tied for second on three-under 141 -- holder Padraig Harrington of Ireland (73), two-time winner Vijay Singh of Fiji (72), US Open champion Lucas Glover (70), Australian Brendan Jones (70) and Briton Ross Fisher (68). <br /><br />Fisher birdied three of four holes from the 14th to surge into a tie with Woods on five-under, but the 28-year-old Englishman bogeyed his last two holes to drop back. <br />On the front nine, big-hitting Spaniard Alvaro Quiros and Graeme McDowell of Britain joined Woods and Harrington in a four-way tie for the lead on four-under before giving way. <br /><br />"It was a tough day all around," Woods told reporters. "The wind was blustery, the greens a little bumpy. A tough day." <br /><br />Woods played some spectacular golf sandwiched inside a bogey start and bogey finish. He took five on the par-four first hole after driving into the left rough and lost a stroke to par after an errant approach on the l8th. <br /><br />"I got off to a poor start and just kind of hung in there," said Woods, who is going after his 15th major crown. "Long way to go. Thirty-six more holes." <br /><br />With winds gusting to 25 mph (40 kph) and firming up the massive greens that grew bumpier as the day progressed, Woods found another gear to leave his pursuers behind. <br />The 33-year-old, seeking a fifth PGA crown to match the record held by fellow Americans Jack Nicklaus and Walter Hagen, made three birdies in a row from the 14th. <br /><br />Woods drove through the green at the par-four 14th, playing at a shortened 299 yards, and two-putted from 22 feet. At the the par-five 15th, he hit his second shot through the green, chipped up close and made another birdie. <br /><br />At 16, he sank another 20-footer to bolster his lead. Woods came to the par-four 18th with a four-shot lead over Harrington, which he maintained as both players took bogey. <br />Jeev Milkha failed to break par for the second successive day but still managed to rise 21 places on the leaderboard for a share of the 48th spot after the halfway stage. The seasoned pro has a total of three-over 147.<br /><br />Agencies<br /><br />Scores (second round, US unless stated): 137: Tiger Woods (67, 70). 141: Vijay Singh (Fiji, 69, 72). Brendan Jones (Aus, 71, 70), Lucas Glover (71, 70), Ross Fisher (Bri, 73, 68), Padraig Harrington (Ire, 68, 73). 142: Ian Poulter (Bri, 72, 70), Lee Westwood (Bri, 70, 72). 143: Ernie Els (SA, 75, 68), Soren Kjeldsen (Den, 70, 73), Yang Yong-eun (SKor, 73, 70), Martin Kaymer (Ger, 73, 70); 144: John Merrick (72, 72), Grant Sturgeon (73, 71), Geoff Ogilvy (Aus, 71, 73), Tim Clark (SA, 76, 68), David Toms (69, 75).</p>
