Roddick, who grew up in South Florida, lost to Istomin the one time they’ve played in the San Jose quarterfinals last month.

Fifth-seeded Philipp Kohlschreiber of Germany also advanced to Friday’s quarterfinals. He defeated 57th-ranked Ivan Dodig of Croatia 6-2, 6-2.

Kohlschreiber saved both break points he faced on serve and took advantage of four of 10 break point opportunities he had on Dodig’s serve. Kohlschreiber broke serve in the fifth and seventh games of the first set and the third and seventh games of the second set.

Kohlschreiber is now 12-5 in 2012 and has reached the semifinals in Auckland and Montpellier, France.

The German’s quarterfinal opponent will be Dudi Sela of Israel, who earned his quarterfinal spot with a 6-4, 6-4 win over Jarkko Nieminen of Finland.

Sela, who also reached the Chennai quarterfinals this season, won 25 of the 30 points when his first serve went into play.

“It was difficult conditions because the wind was swirling,” said Sela, who said the weather is similar to what he’s used to in Israel.

“It was tough to serve and you had to put your first serves in. I think I served very well and I didn’t give him any presents.”
