PORTRUSH, Northern Ireland — Scottie Scheffler was quick to point out the British Open was only at the halfway point at Royal Portrush. Considering the world's No. 1 player was in the lead, it felt like a sprint Saturday for so many players to catch up.

Rory McIlroy will play the weekend at a Royal Portrush Open. But to contend, he'll need to straighten out his driver.

Rory McIlroy carded a 2-under 69 in the second round of The Open to give him back-to-back under-par rounds and, most importantly, a tee time on the weekend.

It was a return six years in the making, and it was a return that perfectly encapsulated Rory McIlroy. Making the trek back to Royal Portrush for The Open Championship -- now as a career grand slam winner -- the Northern Irishman experienced a topsy-turvy day as the hard stuff came easy and the easy stuff came hard.

Rory McIlroy shot 1 under Thursday at Royal Portrush, a better start than the first time he played the British Open at the Northern Ireland course near home.

Disaster on the first when the championship returned to the county Antrim golf course six years ago has made the field very wary as they begin their rounds

Six years ago at Royal Portrush, McIlroy, who grew up less than an hour away, hit his opening shot out of bounds on the par-4 first on his way to a quadruple-bogey 8 and a 79. He pulled his tee shot again, this time around, but it settled safely in the left rough.

Yes. McIlroy debuted at the 2007 British Open as a low amateur. Since then, he has managed one win at the final golf major of the year. McIlroy finally completed the feat at the 2014 British Open, when the tournament was held at the Royal Liverpool Golf Club in Holylake, England.
