With the PGA Championship now in the books after this weekend, the four major championships have been completed in 2018. The PGA Championship is traditionally the final major and is played some time in early August, though it has been held the last weekend in July.
However, next year there is a major change in store. The PGA Championship will be held in May, and will be the second major of the 2019 slate.
The Masters will kick things off, as usual, while the U.S. Open will be the third major and The Open will be last.
Here is more from PGA.com:
The PGA Championship, which is the fourth and final major on the 2018 PGA Tour schedule, will be moved three months earlier in the calendar next year, from August to May. The move was originally announced last year.
Scheduled for May 13-19, 2019, at Bethpage State Park's Black Course (above), the PGA Championship will be the second major played in the 2019 tournament schedule, five weeks after the Masters Tournament and five weeks before the U.S. Open.
Brooks Koepka will defend his title next May. Koepka won this year's PGA Championship by two strokes over Tiger Woods.
Koepka has won back-to-back U.S. Open's, so it isn't out of the question that he repeats at the PGA in 2019.
