Tiger Woods signed up for his first Wyndham Championship knowing a win would definitively keep his season from ending.
He's halfway there.
Woods shot a five-under-par 65 on Friday at Sedgefield Country Club in Greensboro, N.C., to share the second-round lead with rookie Tom Hoge.
"I'm only at the halfway point," Woods said. "Only 36 holes. We've still got a long way to go."
Woods and Hoge were at 11-under 129. Hoge shot a 67.
The sport's biggest name put himself in prime position to contend for his first victory in more than two years, one that would send him into the FedEx Cup playoffs.
Woods followed his best round since 2013 -- a first-day 64 -- with one almost as good.
He made his big move up the leaderboard on the back nine, with birdies on Nos. 12 and 13 and an eagle on the par-five 13th that gave him a share of the lead.
"I just couldn't get anything out of my rounds (before this tournament) and a couple lucky bounces here, take advantage of those opportunities — it's just the flow," Woods said.
Now he'll spend Saturday playing with an unfamiliar rookie. When asked if he would recognize Hoge to see him, Woods responded: "No, I wouldn't. What is it, or him?"
"I look on the Champions Tour leaderboard and I know every one of those guys because I played against them and I played with them," Woods said. "Now I come out here, I don't really know a lot of people."
Davis Love III and Chad Campbell were a stroke back. Campbell shot 65, and the 51-year-old Love had 66.
Brandt Snedeker matched the tournament record with a 61 that put him in a group of six players two strokes behind Woods and Hoge.
DeChambeau reaches semifinals at U.S. Amateur
NCAA champion Bryson DeChambeau beat Ireland's Paul Dunne, 3 and 2, at Olympia Fields to advance to the U.S. Amateur semifinals.
DeChambeau, the SMU player from Clovis, Calif., will face Southern California sophomore Sean Crocker of Westlake Village, Calif.
In the other quarterfinals, Virginia junior Derek Bard of New Hartford, N.Y., rallied to beat Arizona State senior Jon Rahm of Spain, 1 up, and Japan's Kenta Konishi edged Baylor transfer Matthew Perrine of Austin, Texas, 1 up.
DeChambeau won the par-four 11th and 13th with birdies to take a 3-up lead and halved the next three to end the match. Dunne, coming off his senior season at UAB, tied for 30th in the British Open last month after sharing the 54-hole lead.
Three down after 10 holes, Bard won Nos. 11 and 12 with birdies, took the 16th with a par, the 17th with a bogey and halved the 18th for the victory. Rahm is the top-ranked amateur in the world.

Mize has two-shot lead over Couples on Champions Tour

The 56-year-old Mize had a bogey-free round at TPC Snoqualmie Ridge. The 1987 Masters champion won the 2010 Montreal Championship for his lone title on the 50-and-over tour.
Couples, trying to win his hometown event for the first time, was tied for second at 69 with Billy Andrade, Carlos Franco, Jeff Freeman and Chien Soon Lu.
