MEMPHIS, Tenn. – Rory McIlroy shot an 8-under 62 on Saturday at the FedEx St. Jude Invitational to take a one-stroke lead over Brooks Koepka at the World Golf Championships event.

McIlroy, who missed the cut by a stroke last week in the British Open on his home turf in Northern Ireland, rebounded very nicely. He had a nine-birdie, one-bogey round to move from a tie for 17th to the top of the leaderboard at TPC Southwind. The man who shattered the screen of a woman's cellphone with his opening tee shot at Royal Portrush finished the round Saturday with three straight birdies.

McIlroy capped his birdie spurt by rolling in a 27-footer on the par-4 18th after putting his tee shot into a fairway bunker. He had a 12-under 198 total.

Two groups behind McIlroy, Koepka (64) had his chances. The world's top-ranked player finished with three straight pars. Now Koepka and McIlroy, who played the first two rounds together, will play together Sunday in a final round for the first time in their careers.

Second-round leader Matthew Fitzpatrick (69) was third, two strokes back. Marc Leishman (63), Alex Noren (66) and Jon Rahm (68) were three shots behind.
