Tiger Woods has insisted that there is still "a long way to go" after moving into a share of the lead at the halfway mark of the Wyndham Championship.
The 14-time Major champion is without a win in two years and came into this week's tournament at Sedgefield Country Club after missing the cut at the US PGA Championship.
He followed a first-round 64 with a five-under-par 65 to share the lead with fellow American Tom Hoge.
"I'm only at the halfway point," Woods told PGATour.com. "Only 36 holes. We've still got a long way to go.
"I just couldn't get anything out of my rounds (before Wyndham) and a couple lucky bounces here... take advantage of those opportunities - it's just the flow."
Woods and Hoge are one shot clear of two more Americans, Davis Love III and Chad Campbell.
