Akron, USA: World number one Tiger Woods matched the low round of his career with a nine-under-par 61 Friday to seize a seven-stroke lead after the second round of the World Golf Championships Bridgestone Invitational.
Woods, playing his final tuneup for next week's last major tournament of the year at the PGA Championship at Oak Hill, fired an eagle and seven birdies to finish 36 holes on 13-under 127.
"I'm very happy I was able to post that," Woods said. "I just kept thinking, whatever lead I had, let's just keep increasing it. It's at seven now so that's not too bad after two days."
