Steve Williams, a part-time Sunriver resident, will no longer serve as caddie for Tiger Woods, The Associated Press reported Wednesday.

Williams, who has also caddied for golf greats Raymond Floyd and Greg Norman in a 33-year career, had worked as Woods’ caddie since 1999.

Woods had informed Williams “that he needed to make a change,” after the AT&T National tournament ended earlier this month, Williams said in a message on his website.

The parting comes after a tumultuous 18 months for Woods, who has been mired in scandal, injury and uncharacteristic poor play. During that time Woods has fallen from the world’s top-ranked golfer to No. 20 in the current World Golf Rankings.

“Given the circumstances of the past 18 months working through Tiger’s scandal, a new coach and with it a major swing change, and Tiger battling through injuries, I am very disappointed to end our very successful partnership at this time,” said Williams.

The 47-year-old Williams has been caddying for Australian tour player Adam Scott since June’s U.S. Open, a span of three tournaments. Williams, a New Zealander, said he will continue to work for Scott.

“I have had the opportunity to work of late for Australian Adam Scott and will now caddie for him on a permanent basis,” said Williams.
