LONDON -- Lee Westwood's manager says the English golfer has split from coach Pete Cowen and temporary caddie Mike Waite after his disappointing performance at the PGA Championship.
Cowen works with several top golfers, including Darren Clarke, Graeme McDowell and Louis Oosthuizen, but the 39-year-old Westwood believes a fresh approach could improve his chances of finally winning a major.
Westwood's manager Andrew Chandler says "Lee admits he needed to shake things up" and that "he'd lost his focus and his enthusiasm a bit."
His regular caddie, Billy Foster, injured his knee in May and won't return until next year. Mike Kerr, who is normally on the bag for Alvaro Quiros, will take over for two months.
Westwood missed the cut at the PGA Championship, where Rory McIlroy won by eight shots.
