Olympic sprint relay champion Mark Lewis-Francis sounded a warn-ing about his form ahead of next month's Commonwealth Games after clinching victory over Australia's best sprinters.

The 23-year-old Birch-field Harrier won the 100 metres in 10.22 seconds at the Melbourne Cricket Ground, which will host the track and field programme at next month's Games.

Lewis-Francis has been training in Sydney for the last five weeks and took the scalps of all his Australian rivals in his first competition Down Under.

It will have been a massive confidence boost for Lewis-Francis, heightened with his local rivals over two months into their summer season.

Lewis-Francis is adamant that after a change of coach this will be the year he bounces back to the form which saw him crowned world junior 100m gold medallist six years ago.

His decision to move away from Steve Platt, who coached him from his teenage days, and join up with Tony Lester's training group in Windsor, seems to be paying dividends.

"All the things that have been said about me are in the past," he said.

While Lewis-Francis celebrated his excellent start, Coventry Godiva's Marlon Devonish found the pace too hot to handle, finishing last.

Mo Farah produced a second British win when taking the 5,000m in 13mins 40.79secs, well clear of Peter Nowill (13:50.45) with Martin Dent third (13:53.96).

James McIlroy, also competing for the first time since his arrival in Australia, was in winning form. The Ulsterman followed up a slow first lap of 54.5secs to win his 800m race in a time of 1min 47.50secs.
