The reigning Asian Tour number one enjoyed another birdie binge with nine on the card against a double bogey at TPC Kuala Lumpur to lead from defending champion Justin Thomas of the United States and Scotsman Russell Knox, who shot a 71 and 68 respectively in the USD 7 million tournament sanctioned by the Asian Tour and PGA Tour.
Japanese star Hideki Matsuyama battled to a 69 to take a share of fourth place with Americans James Hahn (69) and Derek Fathauer (68) while the day's low round belonged to current Asian Tour Order of Merit leader Scott Hend of Australia, who sizzled with a 63 to move up to joint 17th position.
"It's very important. Obviously it was on my mind today, it was on my mind since I finished my round yesterday actually. I was determined to keep my focus right through the 18 holes," said Lahiri.
With his best finish to date on the PGA Tour being tied fifth at the 2015 PGA Championship, Lahiri is hoping to join countryman Arjun Atwal as the only Indians to win on the PGA Tour but he knows he must go low again on Sunday.

He arrived at the CIMB Classic in confident mood following his stunning finish at the Venetian Macao Open last weekend where he birdied nine of his last 11 holes, including seven straight closing birdies, to get into a play-off, only to lose to Thailand's Pavit Tangkamolprasert.
"After Macao, I was sitting and looking, I have seven seconds and four thirds and a few fourths and fifths for my seven wins. It's painful when you don't get over the line, and when you do, you remember it. You remember what it felt like mentally, and I think that's where you want to recall that feeling," said Lahiri, who only needed 23 putts today.
