A ex LIV Golf player returns the PGA Tour at The Open after his suspension was lifted and ankle monitor was removed just days before the event at Royal Birkdale.
The tournament kicked off in heavy gray mist at the English links course.
The defending champions played the characteristic way they always do in Round 1.
Rory McIlroy had a arduous day.
He shot a 72 and sat well behind the leader at the end of the round.
Rain stopped play for hours early on.
Then wind rose and made it hard to score later in the day.
Officials maintained close watch on the weather as gusts stayed strong and rain threatened for Friday.
