A ex LIV Golf player rejoins the PGA Tour at The Open after his suspension was lifted and ankle monitor came off just days before the event at Royal Birkdale.
The tournament kicked off in heavy gray mist at the English links course.
The current champions played the characteristic way they typically do in Round 1.
Rory McIlroy had a tough day.
He shot a 72 and sat well behind the leader at the end of the round.
Rain halted play for a long spell early on.
Then wind rose and made it hard to score later in the day.
Officials kept close watch on the weather as gusts remained strong and rain loomed for Friday.
