World No. 35 Lahiri, who beat World No. 23 Ryan Palmer in the first match of the round-robin stage, led for almost the entire regulation period, except a couple of times when Rose pulled up to all-square at TPC Harding Park.
"It was a disappointing finish after a tight match," said Lahiri. "I am still in it with one win and one loss. I just need a good day tomorrow (in the third round-robin stage match against Marc Leishman)."
Lahiri did not do anything seriously wrong on the back nine, it was just that Rose produced a couple of great shots at crucial times towards the very end.
"There is still the third match and there could a three-way play-off, let's see," said Lahiri.
He said, "I put enough pressure on him in the end, but Anirban is a great putter. The first hole I looked like I had it won comfortably, he holed a 30-footer. And then he holed another 40-footer or so. It was going to be a tough match, I knew, from that moment."
Rose added, "Anirban played solid golf today. He's dangerous with a putter. And I sort of found that out early in the round. He knocks in a 30-footer for a half. And then knocks in another 35-footer elsewhere in the round (third hole). I knew he was never out of any hole. So it kept me on my toes."
