A 23-year-old New Zealander, Armstrong was in the mix late for a possible win despite starting 19th and being stuck in a multi-car incident that was triggered by Rahal Letterman Lanigan Racing’s Christian Lundgaard in Turn 3 on lap 53 of 100.
In some ways, the incident prompted a pit stop on lap 56 - the last of his four - that was on the same strategy as Chip Ganassi Racing team-mate Scott Dixon, which prompted a massive fuel number to make it to the end.
