Seeded Teams Survive In Kuala Lumpur

The second and third-seeded teams were in action on Wednesday in Kuala Lumpur, and both needed Match Tie-breaks to advance to the quarter-finals.

No. 2 seeds Treat Huey and Henri Kontinen, who took home the St. Petersburg title last weekend, overcame Marcus Daniell and Marcelo Demoliner 4-6, 6-2, 10-6 in 71 minutes. Huey and Kontinen dropped serve in the first game of the match to concede the opening set, but went 2-for-2 on break points in the second set to force a Match Tie-break. Their quarter-final foes will be Santiago Gonzalez and Philipp Petzschner.

Third seeds Eric Butorac and Scott Lipsky also mounted a successful rally, winning 6-7(7), 6-1, 11-9 against Aliaksandr Bury and Andreas Siljestrom. The Americans went down a set and a break, but roared back with three breaks to secure the second set. In the Match Tie-break, Butorac and Lipsky won the next two points from 9/9 to set up a quarter-final meeting with Frantisek Cermak and Radek Stepanek, who battled past Wesley Koolhof and Matwe Middelkoop 6-4, 3-6, 12-10.
