P – Milos Raonic successfully defended his San Jose Open tennis title by routing unseeded Denis Istomin 7-6 (7-3) 6-2 on Sunday.

The 21-year-old Canadian dominated Istomin with his serve, hammering seven aces and winning 90 per cent of his first serve points in the 79-minute match.

Raonic, who had a bye in the first round, didn’t drop a set in four matches at the indoor tournament.

The world No.32 is also a perfect eight-for-eight in tiebreakers at the event over two years.

Raonic won the first set in a tiebreaker, closing it out with a 145mph serve. He jumped out to a 6-1 lead, then dropped the next two points before serving for the set.

Raonic stepped up the attack in a lightning quick second set, going eight-for-eight in his first serve points and winning 89 per cent of his second-serve points.

The Canadian has dropped only two service games in two years in San Jose.

After hip surgery following a slip on Wimbledon’s grass last year stalled his season, Raonic is rising rapidly again. He will head to Memphis next week as one of the favourites.
