Harris English matched his lowest round of the season on Friday, a 64, and with it took the lead into the weekend at the FedEx St. Jude Classic.
The last time English went that low was in the opening round of the HP Byron Nelson Championship. He went on to finish in a tie for 17th that week.
Now the second-year player is looking to take it to another level as he tries for his first career win.
English had five birdies, a hole-out from the fairway for eagle and just one bogey en route to taking a two-stroke lead over Shawn Stefani, who shot 65 Friday.
"I'm still getting comfortable out here," English said. "Just trying to get in the hunt of a golf tournament every time. I've worked very hard the last couple weeks and couple months to get in this position."
Paul Haley II and Scott Stallings are tied for third but are five shots off the lead.
Defending champion Dustin Johnson, playing for the first time since withdrawing from THE PLAYERS Championship with a bad back, is also in contention at 3 under halfway through the event.
David Toms was the last player to repeat in Memphis. He's a stroke back of Johnson.
So is Phil Mickelson, who was four shots better than his opening round with a 67 Friday.
"I let a number of shots slide (Thursday)," Mickelson said. "I made a couple of dumb mistakes, and I think that's why I enjoy the competing element before a big event like the U.S. Open next week.
"And I'm not selling myself out this week. I feel like if I play better (Saturday) than I did today, I've got a low round in me."
