Tomic, at 17 Australia's youngest Davis Cup player in 77 years, crushed Taiwan's Yang Tsung-hua, 6-2, 6-1, 6-1 in the opening singles rubber.

Australia's nominated number one player Peter Luczak built on Tomic's winning start to down Yi Chu-huan Yi, 4-6, 6-3, 6-2, 6-3 and put the hosts 2-0 up heading into Saturday's pivotal doubles.

Carsten Ball and Paul Hanley will team up for the doubles against Yang and Yi.

Non-playing captain John Fitzgerald continually urged Tomic to maintain his focus as the teenager reeled off an accomplished straight sets victory on his Davis Cup debut.

"That was the first time and I handled it quite well. I really liked Fitzy giving me the advice, which worked out well," Tomic said.

"I think we executed our decisions really well today. He said a few things and I did them really well, it pleased him and it pleased me.

"I could't be much happier. Yang's always played well against me and I've had a lot of three-setters with him so today to win in three and to win it quite comfortably was good."

Luczak is Australia's top-ranked player here this weekend after Lleyton Hewitt's recent right hip surgery.

Taiwan are also without their top-ranked player Lu Yen-hsun, who decided to pass on the tournament so that younger teammates could have an opportunity to gain valuable experience.
