Brandt Snedeker took the outright lead at the Sony Open In Hawaii with a second round 5-under par 65 at Waialae Country Club to bring his total to 12-under.
Snedeker, one of five co-leaders after the first round, hit 14 of 18 greens and made no bogeys to take a one-shot lead over Kevin Kisner.
"I feel way more comfortable this week than I did last week. Last week I had a new driver in the bag, had a new ball in play," Snedeker said. "I had some new stuff we were working on with the swing, and after four good days last week, kind of feel more comfortable with how I'm supposed to swing, how I'm supposed to kind of step up to it and know where my miss is going to be."
Vijay Singh, another co-leader after the first round, shot just one-under-par to fall shots behind Snedeker. The 52-year-old Singh is looking to become the oldest winner in PGA Tour history.
The cut at Waialae Country Club was three-under-par and claimed Keegan Bradley, Graeme McDowell and Robert Allenby. Adam Scott, Jimmy Walker and Matt Kuchar will play into the weekend.
