Tiger Woods' continuing woes were highlighted in Monday's world golf rankings, which saw the former No. 1 drop to No. 181.
The 14-time major winner has struggled badly in recent tournaments, and shot a career-worst 85 in the third round at the Memorial on Saturday.

Woods eventually finished last, posting the highest 72-hole score of his career at 302.
That result has seen him fall another nine places in the rankings, with the 39-year-old in danger of dropping out of the top 200 in the near future.
Inside the top 10, the only movers were Jim Furyk and Dustin Johnson.
Furyk climbed above Bubba Watson and Henrik Stenson into third, while Johnson moved ahead of Rickie Fowler into seventh.
Rory McIlroy and Justin Spieth remain atop the rankings.
David Lingmerth, who defeated Justin Rose in a playoff at the Memorial, shot up from 212th to 71st.
