Slingsby, Outteridge prep for SailGP title

Rival Australian skippers Tom Slingsby and Nathan Outteridge tuned up for their $US1 million ($A1.5-million), winner-takes-all showdown by each winning a fleet race on Saturday in the final stop of SailGP's inaugural season.

Slingsby, of Team Australia, won Saturday's first race and Outteridge, of Team Japan, won the third.

They will not compete in Sunday's two fleet races, which will precede their clash for one of the biggest paydays in sailing history.

Slingsby, an Olympic gold medallist and former America's Cup champion, took his season lead to six points over fellow Aussie Outteridge, 225-219.

On the off chance the match race can't be sailed, the season championship would be decided on points.

Team China, skippered by New Zealander Phil Robertson, won their first fleet race this season and are tied with Dylan Fletcher's British crew for third place going into the final day of racing.
