Sam Hornish Jr. (kiri) berhasil memenangkan gelar Kejuaraan Pembalap untuk yang kedua kalinya (gelar kedua secara berturut-turut), sementara
Hélio Castroneves (kanan) menempati posisi kedua di dalam klasemen akhir Kejuaraan Pembalap.
Pada musim 2002, Indy Racing League (IRL) mengalami masa transisi, dengan dua tim juara CART yang sedang bertahan, Team Penske dan Chip Ganassi Racing , bergabung dalam seri dengan entri penuh waktu. Mesin Oldsmobile diubah mereknya menjadi Chevrolet, dan baik Honda maupun Toyota mengumumkan partisipasi mereka dalam seri mulai tahun 2003, sementara Infiniti mengumumkan penarikannya.
Sam Hornish Jr. memenangkan 5 balapan dalam perjalanannya meraih gelar juara keduanya secara beruntun, unggul dari kehebatan Penske, Hélio Castroneves , pemenang dua balapan termasuk Indy 500 dua kali berturut-turut, dalam perjalanan menuju posisi kedua dalam kejuaraan.
