Djokovic puts boot to Sock to reach quarters

World number one Novak Djokovic stormed into the quarter-finals of the Rogers Cup with 6-2 6-1 demolition of Jack Sock on Thursday running his Masters 1000 winning streak to 28 matches. Second seed Andy Murray followed Djokovic into the last eight in equally economic fashion, disposing of Luxembourg's Gilles Muller 6-3 6-2 in a tidy 65 minutes.
