Dolgopolov into Brisbane International 2nd round

Third seed Ukranian Alexandr Dolgopolov fought off a determined Alejandro Falla of Colombia to reach the second round of the Brisbane International on Sunday.

Dolgopolov took the first set in a tiebreak, then overpowered the Colombian in the second to ease to a 7-6 (7/3), 6-2 win.

The 21-year-old Ukranian enjoyed a breakthrough year in 2011, beginning by reaching the quarter-finals of the Australian Open and finishing ranked 15th in the world.

Earlier wildcard James Duckworth repaid the promoter's faith in him when he upset Frenchman Nicolas Mahut 6-4, 6-4 in his first ever match on the main ATP tour.

Duckworth was only granted a wildcard when a late withdrawal saw previous recipient Matthew Ebden elevated to the main draw.

The world No. 275 took full advantage, coming back from 1-4 down in the first set to win five games in a row and breaking Mahut once in the second for an impressive victory.

"I had a pretty good preparation, I had a few tough weeks of training and got myself in the best possible shape I could," Duckworth, 19, said, adding he didn't expect to be playing on the centre court.

"I was fully prepared to play qualifying here - I only got in (to the main draw) at the last minute."
