Jeev Milkha Singh floundered with his iron play and managed only a 76, his highest for the week, and dropped to 51st at the WGC Bridgestone Invitational golf championship.
Jeev, the Asian Tour No. 1 in 2006, finished with 14-over 294 overall at the Firestone Golf Club on Sunday.
Tiger Woods was in brilliant form as he carded a sizzling five-under 65 and cruised to an eight-shot win after trailing by one to Rory Sabbatini (74) at the start of the final day.
Sabbatini and Justin Rose (68) tied for second.
Jeev had two double bogeys on the front and four bogeys on the back nine. On the positive side, he had just two birdies, both on front nine.
Jeev double bogeyed the first and fourth and birdied the second and sixth, but bogeys on 11th, 14th, 16th and 18th spelt the end of any recovery.
Korea's Choi Kyung-ju carded a final round of one-over-par 71 to finish tied 11th. The Asian Tour graduate, a two-time winner on the US Tour this season, completed the week with a four-over-par 284 total.
Thailand's Thongchai Jaidee closed out his week with a 71 for a share of 46th place on 293.
Another Korean, Yang Yong-eun, stumbled to a 78 on Sunday to finish on 295 in 56th place while China's Liang Wen-chong, current leader of the UBS Order of Merit, ended his week in tied 61st position after a 75.
