Patrick;
I don't know the extent or nature of Mr. Hills recent work at Siwanoy, but I thought I stated "I believe it was Art Hills" in my original post, indicating some degree of uncertainty.
Turns out it was. From Hills website comes the following;
Arthur Hills / Steve Forrest and Associates has worked with over 100 courses throughout the United States on golf course renovation and improvement programs. The scope of work can vary from course to course depending on the age and condition of the course. Following are examples of course improvement programs:
Master Plan- an overall plan of improvements for the entire golf course that is within the framework of the existing course routing.
Minor Renovation- may be working with just one component of the golf course such as rebuilding the tee complexes, bunkers, or adding an irrigation pond.
Major renovation- normally includes the complete rebuilding of the greens, extensive bunkering enhancements and may involve changing the routing of some of the golf holes.
Restoration- restoring the original character as designed by a noted architect such as Donald Ross yet within the context of today’s design standards for distance and playability.
Some of the clubs we have worked with most recently:
Barton Hills Country Club, Ann Arbor, MI Kenwood Country Club, Cincinnati, OH
Burning Tree Golf Club, Bethesda, MD Milwaukee Country Club, Milwaukee, WI
Chevy Chase Club, Chevy Chase, MD Oakmont Country Club, Oakmont, PA
Congressional Country Club, Bethesda, MD Siwanoy Country Club, Bronxville, NY
Country Club of North Carolina, Pinehurst, NC The Club at Pelican Bay, Naples, FL
Half Moon Bay Golf Links Half Moon Bay, CA University of Kentucky Golf Club, Lexington, KY
Inverness Club, Toledo, OH Westmoreland Country Club, Wilmette, IL
Hermitage CC, Richmond, VA
I should also add the C&W indicates that Tom Winton, RTJ Sr., and Geoffrey Cornish/Wm. Robinson all made some revisions over the years, but I don't know any of the details.

Do you have evidence to the contrary?
