Orlando, Fla. ? In their own way, Jason Gore and Tiger Woods changed their fortunes Thursday at Bay Hill.

Gore was not seeing any results from an overhaul to his swing until he ran off three birdies over the final four holes for a 5-under 65 that gave him a one-shot lead in the Arnold Palmer Invitational.

Woods was in the water, in the trees and in a foul mood until he had eight consecutive one-putts — including four straight birdies — that put him in a good frame of mind with a 68 on a course where he has won five times as a pro.

“I was not hitting it well, and I had to scramble and grind it out and manage to score,” Woods said. He managed just fine, taking only 24 putts in the first round after ranking 74th in putting out of 79 players at Doral two weeks ago.

Tim Herron and Jeff Overton had 66s.
