Back in 1979, George Fazio and nephew Tom were roundly criticized by Donald Ross fans for removing a classic Ross par-4 on Oak Hill East and replacing it with two new holes, including the bowl-shaped par-3 sixth, which would later become the scene of four aces in two hours during the second round of the 1989 U.S. Open. They also built a pond on another par-3 and relocated the green on the par-4 18th. The club hired golf architect Andrew Green to remodel those holes to bring them more in line with Donald Ross' original style. In addition to putting the final touches (at least for now) on a significant tree removal program, Green re-established Ross' original par-4 hole, then the fifth and now playing as the sixth (pictured here). Reconstruction occurred after the 2019 Senior PGA Championship on the East Course and was completed in May 2020. Oak Hill's East Course hosted the 2023 PGA Championship, won by Brooks Koepka.
