Lewis Hamilton conceded his Indian Grand Prix was "pretty poor" after finishing sixth on a day when his Mercedes teammate Nico Rosberg took second.
Hamilton was 23 seconds behind Rosberg at the finish, saying he destroyed his tires while trapped behind Felipe Massa's slower Ferrari.
"It's good we got some points, but [the problem] was the strategy," said Hamilton. "It was so hard to pass the Ferrari.
"I just tried to hang in there and tried to get past, but destroyed the tires. A pretty poor race for myself, but it's OK, these things happen. It was unfortunate but we've got more races ahead of us."
Rosberg admitted that getting past Massa in the first pit stops was critical to his runner-up finish.
"The start was a bit difficult dropping behind Massa," said the German. "He was definitely slower. I tried to pass him one lap and he got it back. The team did a fantastic strategy to get past him.
"It was important to have a normal weekend, get a lot of points and now we've giving Ferrari a run for their money in the constructors' [title]."
