England's Lee Westwood and Spain's Sergio Garcia, part of Europe's largest 40-something Ryder Cup contingent in 60 years, could be danger men, three-time major winner Jordan Spieth warned Tuesday.

Garcia, 41, was sixth at the BMW Championship and 14th at the Tour Championship last month to end a solid US PGA campaign while Westwood, 48, had back-to-back runner-up efforts at Bay Hill and the Players Championship last March.
