MANAMA (Reuters) - Nico Rosberg planted his Mercedes on pole position for the floodlit Bahrain Grand Prix on Saturday after a last-lap error cost team mate Lewis Hamilton his chance of a qualifying hat-trick.
Rosberg, the Formula One championship leader, had been in Hamilton's shadow throughout practice but struck when it mattered to secure his first pole since Monaco last May with a best lap of one minute 33.185 seconds.
