Hamilton pushing toward 5th F1 title after imperious drive

  Both are four-time F1 champions and vying for a fifth win to move level with Argentine Juan Manuel Fangio and within two titles of F1 great Michael Schumacher's record. But Vettel, who crashed in the rain while leading the German GP in July — where victory would have given him the championship lead — makes mistakes Hamilton simply does not.During the Singapore GP, Vettel hit a wall during Friday practice and lost valuable track preparation time for qualifying. It triggered a set of baffling events and poor decisions unbefitting of such a proud team.His team botched qualifying when a poor strategy call put Vettel and teammate Kimi Raikkonen on the wrong tires. Ferrari compounded that by bringing Vettel in too early for a tire change during Sunday's race, hoping to gain advantage by pre-empting Hamilton's anticipated move. Instead, Vettel lost one place in the race and ended up third, wasting points he cannot afford to lose.Ferrari's mistakes this season have started to pile up, while Mercedes is making the right calls and Hamilton is making the most of it. Hamilton said Vettel's crash in practice was not Mercedes "lucking in," but more about the differing approaches of the rival teams.
