Koepka powers to two-shot lead in Memphis

FedEx Invitational Golf

Defending champion Brooks Koepka fired a superb eight-under par 62 to take a two-stroke lead after the first round of the St Jude Invitational in Memphis on Thursday.

The four-time major winner shot six birdies against one bogey on the front nine before picking up three more birdies in a strong back nine to record his equal-lowest total on the PGA Tour.
