MEMPHIS, Tenn. -- Brooks Koepka has been working hard to fix his game even with an injured left knee.
He put everything together Thursday.
The defending champ matched his career best with an 8-under 62 to take a 2-stroke lead over Rickie Fowler and Brendon Todd after the first round of the FedEx St. Jude Invitational.
A week after missing the cut in Minnesota in the 3M Open, Koepka had nine birdies and a bogey on a windy day at TPC Southwind in the World Golf Championship event. He credits all his work with coaches Claude Harmon and Pete Cowen rather than how comfortable he is on this course.
