NAPA Auto Parts announced Thursday it will sponsor Indianapolis 500 winner Alexander Rossi for two more races.

NAPA signed on with Andretti Autosport for the Indy 500 a little under two weeks before Rossi's surprising victory. The American became the first rookie to win the race since 2001.

He'll now have sponsorship from NAPA through the double-header on Detroit's Belle Isle this weekend.

Rossi's team was put together by Bryan Herta and merged with Andretti Autosport. Michael Andretti said he hoped to continue sponsorship conversations with NAPA beyond Detroit.
