- Lewis Hamilton wins Canadian Grand Prix
- Closes in title race on Nico Rosberg
- Rosberg fifth after first corner tangle with Hamilton
- Sebastian Vettel finishes second
(CNN)Lewis Hamilton dedicated his fifth victory in the Canadian Grand Prix to Muhammad Ali after holding off a determined challenge from Ferrari's Sebastian Vettel Sunday in Montreal.
"Float like a butterfly, sting like a bee. That's for Muhammad Ali," said Hamilton over his race radio in tribute to the former three-time heavyweight boxing champion who died last weekend.
Hamilton's Mercedes teammate Nico Rosberg could only finish fifth after the pair tangled on the first corner and has seen his title lead cut to just nine points.
