Former world No. 1 Lee Westwood and his instructor, Sean Foley, have parted ways after working together for the past seven months.
Foley confirmed the split Thursday morning via text.
"Things just didn't gel,'' Foley said. "Great guy and I wish the best for him.''
Westwood told GolfChannel.com at the Northern Trust Open that he was "going to be working with somebody else,'' but did not disclose the new instructor.
"I just wanted something else, a new way of teaching,'' Westwood said. "I did enjoy working with him.''
Westwood, 40, who took over the No. 1 spot from Woods in 2010 and was atop the rankings for 22 weeks, used to work with instructor Peter Cowen, who teaches several prominent European Tour players, including Henrik Stenson and Graeme McDowell.
With Foley, Westwood quickly found success, taking the 54-hole lead at the Open Championship, where he tied for third. But he has just one top-10 finish since and has not won since the 2012 Nordea Masters, a stretch of more than 18 months. He is now ranked 33rd in the world.
After missing the cut at the Waste Management Phoenix Open two weeks ago, Westwood is in this week's field at Riviera and the WGC-Accenture Match Play Championship next week.
