Indy 500: Alonso tops practice for Fast Nine contenders
Only five of the nine pole position contenders took to the track for the 45-minute session ahead of the Fast Nine shootout, but Alonso’s no-tow speed of 231.317mph was comfortably fastest.
The McLaren Honda Andretti driver grabbed top spot after setting two 231mph laps, ahead of the only Chevrolet runner to lap, Will Power of Team Penske who was on a 230.981mph.
As the track warmed up, however, Alonso’s best was behind the three best no-tow speeds set by the group who can qualify no higher than 10th – Graham Rahal, Ryan Hunter-Reay and Juan Pablo Montoya.
Marco Andretti clocked a 230.796mph, ahead of two of his teammates, defending Indy 500 winner Alexander Rossi on 230.489 and Takuma Sato on 227.532.
Neither Ed Carpenter Racing cars (Carpenter himself and JR Hildebrand) nor Chip Ganassi Racing cars (Scott Dixon and Tony Kanaan) lapped in that final practice session, since ambient conditions for the shootout are expected to be warmer.
Alonso's #29 car is currently undergoing a precautionary engine change.
