American Rickie Fowler fired a second straight 66 on Friday to take a one-shot lead at the Honda Classic at the PGA National in Florida.
Another four-under round took him to eight under but he is only one shot ahead of fellow American Jimmy Walker.
The world number five, priced at 2.25 to win the event, hit four birdies in a flawless round but he did have a scare on the 10th after a poor tee shot.
The 27-year-old has had a solid start to the year after winning the Abu Dhabi HSBC Golf Championship at the end of January.
Speaking after his round, Fowler revealed his delight at his performance once again as he looks to win another title on the PGA Tour.
Fowler told PGA Tour Radio: “I got a nice break on one but kept myself in it with some good up and downs, made some good putts and it was a little bit of a bonus with a birdie on the last.
“I’m definitely pleased with the way I’ve played the last two days.”
Overnight joint leader Sergio Garcia carded a 69 to drop back into third, one ahead of Australian Adam Scott who hit an impressive 65.
However, world number three Rory McIlory missed the cut after he hit a
72 to miss out by one shot.
Defending champion Padraig Harrington recovered from a bad start to card a 68 and he is now one over par going into the third round.
