Tiger Woods' former caddie Steve Williams will be back on the PGA Tour this week, alongside Aaron Baddeley.

Williams, who caddied for Woods during most of his dominance, and also helped Adam Scott win the 2013 Masters, has been hired by Baddeley for a two-week stint.

Baddeley will utilise Williams at the AT&T Byron Nelson and also for next week's Fort Worth Invitational before returning to John Limanti, who has carried Baddeley's clubs since 2016.

"We've been friends for a while, and he sort of got in touch with us over the last year about working just a couple weeks just to sort of show me some of the stuff that he's learned over his career," Baddeley said, via golfchannel.com.

"We sort of figured out that these were the two really good weeks for him to come out."

Williams, in retirement from caddying since parting ways with Scott, will not return on a full-time basis.

Baddeley's two-year PGA Tour exemption for winning the 2016 Barbasol Championship ends in August, and he has just two top-10 finishes since the end of that year.

He is hoping Williams can provide a little spark to get his career back on track.

"There could be a couple things to think about slightly differently, or just how you go about playing the golf course that we can just tweak slightly," Baddeley said.

"You turn a 72 into a 68, or a 68 into a 64. As you know, golf's such a fine line, and if you can save one or two shots a day, at the end of the week that's just massive."
