Four players aced No. 6 on the same day in 1989 U.S. Open at Oak Hill, but there’s a major reason it won’t happen again at 2023 PGA Championship

Here’s perhaps the safest bet for this week’s PGA Championship: Four players won’t make holes-in-one on the same day at No. 6 of Oak Hill’s East Course. Sounds like a silly bet, of course, but it happened during the second round of the 1989 U.S. Open on the East.

There’s no way that exact feat will reoccur in this year’s PGA Championship on the same layout, because that hole no longer exists.
