Bernard Tomic has completed a tumultuous fortnight to successfully defend his title at the Bogota Open.

The Australian No.1 defeated Frenchman Adrian Mannarino 6-1 3-6 6-2 in Sunday’s final to secure his third ATP title, having also won the 2013 Sydney International.

Tomic’s victory comes after the 22-year-old was suspended from Australia’s Davis Cup quarter-final win over Kazakhstan in Darwin for savaging Tennis Australia bosses and then being arrested 10 days ago in Miami following a hotel party.

While Tomic’s immediate Davis Cup future remains uncertain as he refuses to meet with TA president Steve Healey to discuss his family’s issues with the governing body, Sunday’s success was a morale booster ahead of next month’s US Open in New York.

Tomic is now unbeaten in nine matches in the Colombian capital after also lifting the trophy last year with victory over Croatian Ivo Karlovic.

But he had to fight hard against Mannarino, who fought back to take the second set and threatened to go on with the job in the deciding set.

Tomic sent down nine aces and saved five of the seven break points he faced to prevail after one hour and 32 minutes.

The second seed collected a cheque for $US124,325 ($A170,930) and rose four rankings spots to No.25 in the world.
