But, with 54 holes left, the Claret Jug is still very much up for grabs. Scheffler is paired up with Matt Fitzpatrick, who held a share of the lead after Thursday and then backed that up with a 5-under 66 on Friday. He's starting just a shot back from Scheffler. Brian Harman and Haotong Li are tied at 8-under to start the day, too.

Widespread showers in the morning become scattered in the afternoon on Friday, but forecasters expect a much lighter wind of 5-10 mph coming from the southwest with a high temperature around 65 degrees. Much of the same Saturday. Cloudy with off-and-on rain, high temperatures in the mid 60s and winds from the southeast at 5-10 mph.

Shane Lowry unleashing F-bomb rants during golf tournaments is certainly nothing new. He did it at this year's PGA Championship. He did it at last year's British Open. He, well, you get the point. But what happened on Friday was still a bit shocking from the Irishman.

The early wave has the advantage. Rain has arrived at Royal Portrush, just as World No. 1 Scottie Scheffler hits the course. It's spotty around the course — it's pouring at 18, where Rory McIlroy is trying to finish — but clearly those already in the clubhouse — including leader Brian Harman — are the beneficiaries.
