Lee Westwood poised for emotional reunion with caddie Billy Foster at Tiger Woods' World Challenge "Everyone knows that Lee and Billy were a great partnership and it made sense that now Billy is fully fit again that the partnership reforms," Chandler told Telegraph Sport. They laugh at the same jokes, are both very quick-witted, and Billy knows when something needs saying to Lee. And, of course, he's a great caddie. So they've had their heart-to-heart, sorted out whatever needed sorting out, and Billy will be back on Lee's bag permanently, starting at Tiger's event next week. Mike is a top lad, a class act and took Lee's decision as we knew he would. Kerr would be one of the first to recognise the special chemistry which existed between Westwood and Foster. As they scaled the rankings, they became one of the best-known and most popular duos on the circuit until disaster struck Foster. On the eve of the Quail Hollow Championship in Charlotte, Foster was taking part in a friendly kickabout when he felt his body move one way and his right leg the other. Originally, Foster believed he would return within weeks, but a scan revealed he required extensive surgery to his shattered right knee. Despite the grim prognosis, Westwood vowed to keep his bag open for the then 46-year-old with whom, during a three-year alliance, he had amassed six major top-threes and won eight times on the way to replacing Woods as the game's No 1. But the recuperation did not go well for Foster and, after waiting six months, Westwood phoned the Yorkshireman with the news he was dreading. Foster was left to face what he later called "a financial and personal nightmare" and while he understood Westwood's logic in taking the chance to sign up the highly-rated Kerr, he admitted to being "devastated." "It felt like my missus had run off with my best mate," Foster said. It was probably the favourite job I've ever had. Considering that Foster had previously worked for Seve Ballesteros, Darren Clarke, Sergio Garcia and, even for one week, with Woods himself, his commendation highlighted their closeness. As he embarked on a recovery programme overseen by Lancashire cricket physiotherapist David Roberts, Foster paid the bills with after-dinner speaking before eventually returning at Wentworth in May after three operations and 13 months on the sidelines. After stints with another former employer in Thomas Bjorn and then more latterly with Grace, Foster believes his knee is finally healed. "There's the odd cracking, but I'm not getting any major grief," he said. Westwood, who has yet to win in 2013, will partner Ian Poulter in the Shark Shootout in the week following the World Challenge and will then re-emerge at the Farmers Insurance Open at Torrey Pines - where he finished third at the 2008 US Open - in January. "It's been a year of transition with Lee, what with moving his family over to Florida and everything," Chandler said. We saw glimpses of the real Lee Westwood at Dubai [where he finished fifth] two weeks ago and I'm sure that, with Billy back on the bag, it'll all come right again. While Foster is thankful for his career's new lease of life, Steve Williams revealed that this will be his last full season on Tour as he concentrates on saloon-car racing. The brash Kiwi, who caddied for Woods in 13 of his 14 major wins, helped Adam Scott make his major breakthrough at the Masters in April and the Australian is hopeful of changing his mind about going into semi-retirement. "Steve was honest with me a couple of years ago and said he didn't have long in him," Scott said. If I play really good next year maybe I can persuade him to go one more season. He turns 50 next month and is getting along in years. Five times Westwood and Foster came close in a major 2008 US Open Torrey Pines, 3rd Westwood plays with Tiger Woods in the last round and matches him shot for shot until the final hole. Woods, however, holes the 20-footer to force the play-off with Rocco Mediate, while a similar effort for Westwood slides by. 2009 Open Turnberry, 3rd Westwood is two ahead after nine holes of the final round, but is overhauled by Tom Watson. Playing the 18th Westwood believes he needs a birdie to catch the veteran so he charges his first putt. He then misses the 10-footer for par and watches in despair as Watson also bogeys the last. 2010 Masters Augusta, 2nd After leading from the second round, a miraculous short-game display from Phil Mickelson leaves Westwood three shots short in second place. Mickelson's six iron off the pine needles between the trees on the 13th is hailed as one of the game's greatest shots. 2010 Open St Andrews Despite struggling with a calf injury which was to force him out of the US PGA the following month, as well as being on the wrong side of the draw, Westwood puts up a brave performance to finish second to South African Louis Oosthuizen. 2012 Masters Augusta, 3rd The last major Westwood and Foster in which were a duo before the latter's knee injury. Westwood ends two off the winner Bubba Watson but Foster calls his performance "one of the best ball-striking displays I've ever seen."
