SportsLine's model simulated the 2025 British Open 10,000 times and revealed its PGA Tour golf picks for Scottie Scheffler, Rory McIlroy and others from Royal Portrush

The final major of the year is here as players hit the course at Royal Portrush for the 2025 Open Championship.

The first day of the 2025 Open Championship is expected to be rainy, with periods of heavy rain that could accumulate up to a quarter of an inch. The high temperature is expected to be around 69 degrees, with a low of 57 degrees, and winds will range from 10 to 20 miles per hour, according to The Weather Channel.

Rain showers can be expected at times for the 153rd Open Championship, which is being hosted on the coast of Northern Ireland.

With regards to the Open Championship specifically Rahm has also been on a heater as of late. With the exception of 2022 (T34) Rahm has top 10 finishes since 2021 (in order... T3, T2 and T7 last year). Golf is a game where crazy things can happen, but the point here is that Jon Rahm is sort of hiding in plain sight.

Open Championship is only a days away from teeing off. Here are the predictions, odds and how to watch the last major of the year.

The 2025 Open Championship is a tournament for long shots. Shane Lowry won at this year’s host course, the Royal Portrush Golf Club, in 2019 as a +8000 long shot before he teed off in Round 1. He wasn’t a favorite to win before Round 2 or Round 3 before becoming the overwhelming favorite heading into the final round.
