IndyCar leader Helio Castroneves arrives in Brazil hoping to stay ahead of teammate Will Power

Helio Castroneves can't count on home advantage against rival teammate Will Power at the Sao Paulo 300 on Sunday.

Castroneves, the IndyCar Series leader, is one of the home-crowd favorites in Brazil. But it's his Penske teammate from Australia who arrives heavily favored on the streets of Sao Paulo after winning all three races at the temporary Anhembi track.

Castroneves boosts three straight top-10 finishes coming into the race. He knows he'll have to get past the "King of Sao Paulo" to improve his chances of staying atop the drivers' standings following Sunday's race.
