Delray Beach, Florida, 23 February 2011 | AFP

Australia’s Marinko Matosevic has been dumped out of Delray Beach International Championships in Florida, going down 3-6 6-1 6-2 to Israel’s Dudi Sela.

The Victorian, who is ranked 135 in the world, qualified for the main draw on Monday and took top seed Andy Roddick’s position in the draw after the American withdrew due to illness.

Matosevic looked strong in the opening set, taking an early break against the world No.91, but fell apart in the second and third, winning just three games.

Sela will now meet Croatia’s Ivan Dodig who reached the second round after dispatching Russian Igor Kunitsyn 6-4 2-6 6-3.

US second seed Mardy Fish needed only 20 minutes to get through when German rival Bjorn Phau retired.

Fish led 5-0 and had dropped only six points in the match, breaking Phau twice before the German halted the match.

The American will now meet Brazil’s Ricardo Mello.

South African fifth seed Kevin Anderson rallied to beat US lucky loser Donald Young 6-7(5) 7-6(4) 6-2 after two hours and 30 minutes, booking a clash with Frenchman Florent Serra.

Serbian sixth seed Janko Tipsarevic also advanced, winning an epic marathon tie-breaker and a lopsided one to eliminate Ivo Karlovic 7-6(14) 7-6(1) despite 18 aces from the Croatian, who lost in last year’s final.

Tipsarevic will next face Slovenian qualifier Blaz Kavcic, who eliminated Colombia’s Robert Farah 6-1 6-4.

Japan’s Kei Nishikori also opened with a victory, downing Argentina’s Brian Dabul 6-2 7-6(5).

He will next face US wild card James Blake, who ousted German seventh seed Benjamin Becker on Monday.

Colombia’s Alejandro Falla advanced 6-1 2-0 over Czech lucky loser Jan Halek, who retired 27 minutes into their first-round match.

Falla will next face Wednesday’s winner between Argentina’s Leonardo Mayer and French eighth seed Adrian Mannarino.
