Australia’s Adam Scott won the Bridgestone Invitational on Sunday, posting a final-round 65 to notch a four-stroke victory over Luke Donald and Rickie Fowler. Scott, with Tiger Woods’ former caddie Steve Williams on his bag, finished with a four-round total of 17-under 263. The Australian won his first elite World Golf Championships title. “I felt good today,” said Scott, who finished with a flourish with a birdie at the 72nd hole. “I stayed so patient. I picked my moments.” World number one Donald and Fowler both shot 66 for 267 while Japanese teen phenom Ryo Ishikawa carded a 69 to finish with a share of fourth alongside Australian Jason Day (69) on 268. Ishikawa, playing in the last group, challenged for the lead but Scott pulled away with birdies at 12 and 14 as the 19-year-old Japanese star three-putted 15 to fall back. “I was able to play well to be at least on top for a moment in the first half of the game today,” Ishikawa said.
