Diamond Run Golf Club, is a Private, 18 hole golf course located in Sewickley, Pennsylvania.
The course was designed by Gary Player and is a Gary Player signature course. The course officially opened on Wednesday, September 14, 1994, when Player along with local celebrities and golf enthusiasts played an opening day round of golf.
Despite its location in hilly Western Pennsylvania, the course plays hilly on only three holes: #12 plays uphill, with a 70-foot elevation increase from tee to green (the same uphill slope as No. 8 at Augusta National in Georgia), while #9 and #14, both par 5, play downhill.
