Northern Ireland's Graeme McDowell is leading the field by one after adding a 71 to 67-67 on first two days to get to 11-under 205. Japan's Hiroshi Iwata (73-65-68) was second at 10-under 206 and Martin Kaymer (69-72-66) was third at nine-under 207 alongside Bubba Watson (71-67-69).
Lahiri, who carded 74 and 70 in his first two rounds, is now two-over 218 for three rounds and will need a good solid final round for a good finish.
Lahiri has suffered a double bogey each of the three days. In the second round, he had four birdies and a double bogey and on the first day it was three birdies, three bogeys and a double.
After enjoying a brief resurgence with a second round 70, Lahiri stumbled to another 74 like his opening day. The Indian, a five-time Asian Tour winner, started off promisingly with a birdie on the second hole but his game started to unravel with a bogey on four followed by a double-bogey-five on six.
"My game's still there and I don't have to reinvent the wheel. It's just a matter of getting the ball onto the fairway and taking advantage of the opportunities which were far and few today," said Lahiri.
