The PGA Tour cut rule has long been reducing a field after 36 holes to the “top 70 professionals and ties.” With the advent of the 2016-17 season, however, that rule has been slightly tweaked.
The new PGA Tour cut rule doesn’t care whether a player in the field is a professional or an amateur; they count toward the cut line the same way moving forward. That means the top 70 players and ties — regardless of professional or amateur status — will make the cut on the weekend.
In the past, the amateur addendum has saved the cut line for scores of professionals who were able to get to the weekend on the back of being part of the top 70 (and ties) pros. No longer, according to the Associated Press.
We can only also assume that this change applies to the PGA Tour’s MDF rule, which institutes a secondary cut after the third round when 78 or more players make the 36-hole cut.
