A fair amount of work at RTJ was done by Kyle Phillips.
From his web site, regarding his recent work, "The major architectural activity took place on holes 14, 15, and 18 along with some work on No. 4 green and No. 9 tee. The No. 15 and No. 18 fairways were rebuilt from the landing areas to the greens, and the No. 9 tee was expanded and improved at the spots where members wanted to play. The most noticeable renovation, however, was made at the layout’s finishing hole.
“The old green sat up quite a ways above the lake,” says Phillips. “There was always a desire by the members to get the green nearer to the lake.
Both the PGA and the RTJ membership played big roles in the upgrades. The changes were geared for the long-term health of the venue and not just to accommodate the Presidents Cup every so often.
“Members of the PGA Tour had their issues and the club wanted to know how that theory would be applied, if it would fit in with the original design,” says Phillips. “ You have a very astute membership there. They take a lot of pride in their golf course, and rightly so.”"
