Indianapolis 500 winner Alexander Rossi has a new sponsor for his next oval race.

Castrol Edge will be the primary sponsor on the No. 98 Honda for the IndyCar Series rookie on Saturday night at Texas Motor Speedway. The car was unveiled before a practice session Friday.

NAPA Auto Parts had signed on with Andretti Autosport for the Indy 500 a little under two weeks before Rossi became the first rookie to win the race since 2001. NAPA then stayed on with Rossi through last weekend's doubleheader on the road course at Belle Isle.

Rossi's team was put together by Bryan Herta and merged with Andretti Autosport.
