Pole is key to Lewis' hopes
Lewis Hamilton will be looking for his fourth win of the season at this weekend's Spanish Grand Prix, and it will be hard to stop the defending world champion if he gets another pole position on a Catalunya track where overtaking is notoriously difficult.
Eighteen of 24 races here have been won from pole, and Hamilton has started from pole in all four races this season. The only hiccup in an otherwise perfect campaign was when four-time world champion Sebastian Vettel beat him at the Malaysian GP, with Hamilton finishing second.
Hamilton leads team-mate Nico Rosberg by 27 points and Vettel by 28. Rosberg is frustrated with one win in the past 15 races.
