New Zealand doubles player Artem Sitak has been beaten in his second ATP doubles final in three weeks.
Sitak and his Dutch partner Wesley Koolhof have lost 6-4 6-2 to Argentine pair, Federico Delbonis and Maximo Gonzalez in the final of the ATP 250 tournament in Sao Paulo, Brazil in 1 hr 12.
Sitak and Koolhof got off to slow start and were broken in their second service game and while they broke straight back, Gonzalez and Delbonis broke again to take the opening set.
It wasn't as if Sitak and Koolhof didn't have chances on the return of serve, but they managed to convert just one of eight break point chances in the match while their opponents converted four of seven.
Gonzalez and Delbonis broke at the start of the second set and never looked back, breaking again to close out a comfortable victory.
