Tiger Woods made a run at 59, one of the last items missing from his resume.
Instead, he had to be content by tying his career best with a 9-under 61 and building a seven-shot lead Friday through 36 holes at the Bridgestone Invitational.
Pursuing his eighth victory at Firestone Country Club, Woods opened birdie-eagle. He had two more birdies on the front nine, then had four in a row to start the back nine in light rain.
Needing to go only 2 under over his last five holes, he missed birdie putts inside 10 feet at 15 and 17, but saved par on the last with a 25-footer.
