Dan Evans got Great Britain's ATP Cup campaign off to a winning start with a straight-set victory in the opening singles tie against Germany.
British number two Evans breezed past Jan-Lennard Struff 6-1 6-2 in Sydney.
His win gave GB the early advantage with Cameron Norrie facing world number three Alexander Zverev in the second singles rubber from 08:00 GMT.
Jamie Murray and Joe Salisbury will then play Tim Putz and Kevin Krawietz in the doubles.
This is the third edition of the ATP Cup, which features 16 countries competing in four groups at two venues in Sydney - the Ken Rosewall Arena and Qudos Bank Arena.
