MELBOURNE: Roger Federer received a timely confidence boost ahead of the Australian Open after lifting his second warm-up title in five years at the Kooyong Classic Saturday.

The world number two will start his bid Monday for a fourth title at Melbourne Park, bolstered by a near-perfect tune-up this week at suburban Kooyong which ended in a 6-1, 6-3 win over Swiss compatriot Stanislas Wawrinka in the final Saturday.

After labouring a year ago with the effects of a glandular fever which coloured the first half of his season, Federer's health is not currently an issue.

"I'm always confident entering any grand slam because of all the success I've had the last six years," the 13-time grand slam champion said after his 57-minute match against 16th-ranked Wawrinka, with whom he lifted the Beijing doubles gold medal last August.

"I always feel at the end of the day I'm going to play well at the slams and it will take an incredible performance from someone else to beat me."

Federer improved his record against his Davis Cup teammate to 3-0.
