World number one Woods, back in action for the first time since winning the British Open two weeks ago, vaulted into a tie for second place with a 66 that included six birdies and an eagle-two at the 14th. Woods, eight off the pace at the start of the day, picked up seven shots in seven holes from the par-three 11th on his way to a scorching back nine of six-under 30.
However, the US Masters champion began and ended his round with a bogey and had to settle for a share of second with fellow American Zach Johnson, who carded a 69. World number two Singh, following opening rounds of 65, 66 and 63, clinched the 28th title of his PGA Tour career and his third Buick Open crown with a blemish-free display that included just a pair of birdies.
