After two rounds in Grand Blanc, Mich., hes set to kill two birds with one Nike Tour Accuracy stone ' preparing for the seasons final major and winning the week before.
Woods fired a 63 Friday to take a four-shot lead over Ryder Cup teammate Scott Verplank (65) and J.J. Henry (67). The worlds No. 1 has made 12 birdies, one eagle and no bogeys through 36 holes.
'I hit the ball really well today,' said Woods. 'It was an awful lot of fun being out there and hitting the ball this way. I made some putts early in the round, got momentum, got rolling and made a great save. But overall, I didn't really put myself in a whole lot of trouble.'
Tigers flawless round of 63
Woods has won 15 of 19 tournaments he has led or been the co-leader of after 36 holes.
This event is one of only three on the PGA Tour that Woods has played at least three times and has yet to win (Nissan and Phoenix). Should he knock this one off his checklist, hell try and become the first player since Lee Trevino, in 1971, to win in back-to-back weeks with the latter being a major.
The PGA Championship takes place next week in Chaska, Minn.
Woods started the second round two off the lead, but vaulted past everyone with five birdies over his first eight holes. He moved to 10-under-par with a 25-foot birdie at the eighth - which died into the left-hand side of the cup - and stayed there by rolling in a 12-footer for par at the ninth.
'Making bogey just leaves a bad taste in your mouth,' said Woods. 'I hit a good putt that went right in the hole and kept the momentum going.'
Tigers accuracy was on display at the par-3 11th, when he stuck a 6-iron from 190 yards to four feet; the birdie was his sixth of the day.
He looked to increase his lead at the par-5 13th, but pushed his tee shot behind a tree in the right rough. He played a cut-shot from 236 into the left greenside bunker, but wasnt able to get up and down for birdie.
He atoned, however, by driving the green on the 322-yard, par-4 14th and two-putting for a two-shot lead, at 12-under.
After a horseshoe lip-out at 15, Woods laced a 2-iron out of the rough on the par-5 16th from 266 yards to six feet and made eagle to take a four-stroke advantage.
He had a seven-footer for birdie at the last, but settled for par.
