New Zealand's Artem Sitak and his German doubles partner Benjamin Becker have advanced to the second round of the men's doubles tournament at the US Open.
They have knocked out the No 14 seeds Treat Huey from the Philippines and Britain's Dominic Inglot 7-6 3-6 6-2 in a match that lasted 106 minutes.
It is Sitak's first appearance in a Grand Slam and he got to play at the US Open because of some outstanding doubles results in the last few months to get his ranking up to 78.
"I'm really excited about my first match win in the slam. Especially being up against the 14th best team in the world," Sitak said.
"These last six to seven weeks have been amazing, winning my maiden ATP title in Stuttgart and then winning a big challenger with fellow Kiwi Marcus Daniell.
"I'm looking forward to my second round match, and really enjoying the grand slam atmosphere. After the US Open I will continue on the ATP tour, playing the Asian swing."
In the second round, Sitak and Becker, who famously was the last player to ever beat Andre Agassi, play the winner of the match between Austin Krajicek and John-Patrick Smith and Bradley Klahn and Tim Smyczek.
If they win that match, they could find themselves up against the Bryan Brothers, Mike and Bob, in the round of 16.
The other New Zealander in the men's doubles, Michael Venus and his partner Mikhail Kukushkin, are likely to play their first round doubles match against Feliciano Lopez and Juan Monaco on Friday.
