Tiger Woods won the Bridgestone Invitational for the eighth time Sunday in emphatic style.
Woods's seven-stroke victory in the elite World Golf Championships event immediately raises expectations that he can end a five-year major title drought at next week's PGA Championship at Oak Hill.
Golf's world number one hasn't added to his 14 major titles since winning the 2008 US Open.
But there was no better place for him to warm up for Oak Hill than Firestone Country Club, a course that Woods said "just fits my eye".
In blustery conditions, and with a seven-stroke lead going into the fourth round, Woods posted an even-par 70.
He led by as many as nine during the round, but was happy to finish on 15-under par 265, seven strokes in front of 2012 champion Keegan Bradley and Sweden's Henrik Stenson.
Bradley carded a final-round 67 and Stenson a 70.
"Today I was just conservative, just tried to make pars," said Woods, whose round included one birdie and one bogey.
He had taken a seven-stroke lead on Friday with a nine-under par 61 in the second round, and maintained the same cushion through 54 holes.
"I figured the highest score I could shoot today was going to be 70 and force the guys to have to shoot 63s and 62s. I felt this was a perfect day to protect."
