With inclement weather expected in the Memphis area on Friday, tee times for the second round of the WGC-FedEx St. Jude Invitational have been moved up to start between 8-10 a.m. ET in hopes that the entire second round is played before weather threatens playing conditions.

All eyes will be on leader Brooks Koepka after he fired a 62 in the opening round to take the leader. Koepka won this event last year and is looking to do the same again after struggling of late to find his form. He seems primed and ready to take on the PGA Championship next week, but needs to finish strong in Memphis. He'll have plenty of challengers, including Rickie Fowler, who sits just two back heading into Friday's action.

Below are the complete list of tee times and featured groups to follow on Friday in Memphis.

All times Eastern. Featured groups are italicized.
