Swiss world number three Roger Federer downed Bernard Tomic to level the Davis Cup World Group playoff tie at 2-2 between Australia and Switzerland on Sunday.
In warm conditions and with swirling winds, Federer proved too good for the 18-year-old Tomic, winning 6-2 7-5 3-6 6-3.
Lleyton Hewitt will take on Stanislas Wawrinka in the final match, with the winner of that rubber securing the tie and promotion to the 16-team World Group for 2012.
