An inspired Milos Raonic toppled Roger Federer 6-4, 6-4 to win the Brisbane International on Sunday and avenge his defeat to the Swiss master in last year's final.

Raonic unleashed his usual serving blitz but it was the rangy Canadian's groundstrokes that impressed the most as he outwitted the Swiss with a masterful display of clean hitting from the baseline.

Federer, irrepressible in his semifinal win over Dominic Thiem, was off-color from the start at Pat Rafter Arena and his 25-year-old opponent feasted repeatedly on his wayward backhand.
