Lleyton Hewitt and Chris Guccione upset Roger Federer and Stanislas Wawrinka in doubles Saturday to give Australia a 2-1 lead in the Davis Cup match against Switzerland.

The Australian pair rallied for a 2-6, 6-4, 6-2, 7-6 (5) victory that means the Swiss pair must win both of Sunday's reverse singles matches to win.

Teenager Bernard Tomic will meet No. 3-ranked Federer on Sunday, with Hewitt to play Wawrinka in the last singles match.

Federer beat Hewitt on Friday to level the tie after Tomic had opened with a win over Wawrinka.
