Over 150 of the world's best male golfers are taking part in this year's PGA Championship at Valhalla Golf Club in Louisville, Kentucky as the second men's Major begins.
Courtesy of a slightly softer course which features friendlier fairway grass to the last time the PGA Championship took place here in 2014, a relatively low winning score is expected compared to previous editions. That is despite the extra length many players have mentioned has been added.
That is not to say it will be plain sailing for the competitors, however, far from it. Several men teeing it up this week have mentioned how brutal the rough can be and have therefore placed a premium on keeping their golf ball on the shortest grass possible.
Players such as Rory McIlroy and Bryson DeChambeau might have the distance on their rivals, but that power will be wasted if they are forced to play back into position too often.
A handful of the Ryder Cup duos' peers - Dustin Johnson, Adrian Meronk, and Michael Block - are struggling to make the weekend following poor starts that have placed them comfortably over par, while the leaders are closing in on 10-under already.
What is the cut at the PGA Championship?
The top 70 and ties from the 156-man field will make the weekend at Valhalla, which is the same number as The Open. As it stands, the cut mark is likely to sit a few shots over par by close of play on Friday.
At Oak Hill in Rochester, New York last year, the cut fell at five-over as Brooks Koepka went on to pick up his third Wanamaker Trophy for a fifth career Major.
The year before at a tournament where the cut was four-over, Justin Thomas fought back to secure a second PGA Championship in a playoff against Will Zalatoris.
At a regular PGA Tour event, the top 65 and ties after 36 holes advance to the weekend. As for the other Majors, it's only the top 50 and ties that make the cut at The Masters, while it's the low 60 and ties that progress through to the weekend at the US Open.
