Baku - Lewis Hamilton said he was "too friendly" to his triumphant Mercedes team-mate Valtteri Bottas at the opening corner of Sunday's Azerbaijan Grand Prix.
The defending five-time world champion made a dazzling start from second on the grid to draw level with Bottas, but said he "basically, gave it to him" as the pair duelled for the lead on the first lap.
Bottas' win lifted him one point clear of Hamilton in the drivers championship thanks to his fastest lap at the season-opening Australian Grand Prix.
Hamilton finished second after what he described him as an "under-par" performance through the Baku weekend.
"It's not our strongest race in the season and this has always been a bit of a difficult race for me," he said.
