Sebastien Rosseler gave the US-based RadioShack squad its first taste of victory by winning the fourth stage of the Tour of the Algarve in Portugal on Saturday.
Rosseler launched a solo bid for the stage win after attacking five riders who had accompanied the Belgian on an escape.
Rosseler's former breakaway companions Frenchman Mickael Delage (Omega Pharma-Lotto) came home in second, with Spaniard Imanol Erviti (Caisse d'Epargne) in third.
After Friday's frenetic mountain-top finish, the overall contenders were content to ease off ahead of Sunday's decisive individual time trial - the final stage of the race.
Race leader Alberto Contador (Astana) naturally ranks as the favourite to defend his 2009 win, but he'll have to contend with an assault from RadioShack duo Tiago Machado and Levi Leipheimer - currently second and third on GC - who will undoubtedly have been buoyed by their team-mate's stage win.
We'll also be watching out for Britain's David Millar in the 17.2km test against the clock, which on paper looks to play to the Garmin man's strengths.
