Lee Westwood has done a bit of housecleaning.
After missing the cut at the PGA Championship, the world No. 4 ended ties with coach Pete Cowen and interim caddie Mike Waite.
Agent Andrew "Chubby" Chandler said Westwood was not getting enough attention from his coach.
"Parting company with Pete is because he's passing on advice to Lee, but he's not around to follow it through," Chandler said, according to multiple reports.
"Lee is very structured about going to the gym, but not about practicing. Pete was here for two days with Graeme McDowell this week when Lee wanted to work with him, so it just wasn't working out. Lee's the sort who needs someone standing over him, making him hit chip after chip and telling him what he's doing wrong."
Westwood had been working with Waite since regular looper Billy Foster was injured in a charity soccer match ahead of the Wells Fargo Championship. He has hired Mike Kerr as his latest caddie.
