Reece Young: Alonso is absolutely next level. Leading in his first attempt in Indy 500. He is driving incredibly.

It's fascinating to watch Fernando Alonso get up to speed so quickly. He sat back early on, didn't charge away and instead observed what others were doing. He's now sussed out his best modes of attack, highlighted by a brilliant move on Alexander Rossi where he tucked in behind him before moving out wide and attacking.

Juan Pablo Montoya is briefly the leader as he leaves it late to pit. Eventually he heads in but stalls his car! It's a slow stop and that will cost him.

Tony Kanaan pits from the lead for a change of tyres. Ed Carpenters is the new leader but looks like Kanaan will kick off a flurry of stops.
