Milos Raonic of Canada upset top-seeded Tomas Berdych of the Czech Republic 7-6 (4), 6-3 to claim his fifth title at the Thailand Open on Sunday.
The No. 11-ranked Raonic put up 18 aces to beat his No. 6-ranked opponent in the final at the Impact Arena in one hour, 17 minutes.
In the doubles final, third-seeded Jamie Murray of Great Britain and John Peers of Australia beat fourth-seeded Tomasz Bednarek of Poland and Johan Brunstrom of Sweden 6-3, 3-6, 10-6.
It was Raonic's fifth tour victory, adding to the three in San Jose from 2011-13 and Chennai in 2012. He also improved his unbeaten record over Berdych to 2-0 after also beating the Czech player in the Cincinnati Masters last year.
Berdych had his chances in the match with a set point at 6-5 in the first but Raonic used his big serve to force a weak return before sending a forehand winner to escape. The Canadian player then relied on powerful serves to force the tie-break, which he sealed with another booming serve.
