SINGAPORE (AP) -- Lewis Hamilton sounds unsure of just one thing: whether Ferrari can bounce back after he dealt another crushing blow to Sebastian Vettel's title hopes.
Hamilton was imperious at the Singapore Grand Prix, securing one of the best pole positions of his Formula One career with an astonishing drive in qualifying and then controlling Sunday's race perfectly.
It all went so smoothly for Mercedes as Hamilton moved 40 points ahead of Vettel with six races left in the season. But for Ferrari, it was yet another weekend on the back foot.
These are big ''Ifs'' for a Ferrari team lurching into crisis after a strong start - as Vettel won the first two races and four of the first 10. They were neck and neck heading into the summer, but Hamilton has won four of the past five races despite acknowledging his car is not as quick.
