OSAKA -- Japan Saturday took an insurmountable, 3-0 lead over the Philippines to secure a place in the second round of the Davis Cup Asia-Oceania zone Group 1.

After two singles wins Friday, Takao Suzuki teamed up with Toshihide Matsui to beat Treat Conrad Huey and Cecil Mamiit 6-4, 6-4, 6-3 in the doubles of the best-of-five contest.

On Friday, Tatsuma Ito needed three hours and 13 minutes to score a 3-6, 6-3, 6-4, 3-6, 6-4 win over 698th-ranked Huey in the opener.

Japan's number two Go Soeda followed him by storming back from behind to beat Cecil Mamitt 6-7 (4/7), 6-3, 6-3, 6-3 for a 2-0 lead.

Ito is currently Japan's top-ranked player after Kei Nishikori dropped to 898th this week with an injury to his right elbow that has forced him out of action for almost a year.

Japan will play Australia in the second round from May 7-9, vying for a place in the play-off for the World Group. Australia also took a 3-0 lead over Taiwan to reach the second round.
