Josef Newgarden cruised to his first IndyCar series win of 2016 after dominating Sunday's Iowa Corn 300.
The 25-year-old took the lead early in the race and did not look back, leading an IndyCar record 282 laps.
It was Newgarden's third win in the series after topping the podium twice in 2015, while he also finished runner-up at last year's event in Iowa.
Sunday's win was all the more remarkable considering he was driving with a fractured clavicle, suffered during his horror crash in Texas last month.
"My right hand was killing me," Ed Carpenter Racing driver Newgarden said post-race. "I hate having a copout, that I'm having a hard time because of the injuries. But it was tough.
He added: "What a great car. We got great cars and today's was the best car we've ever had."
Team Penske's Simon Pagenaud started from pole position, but Newgarden managed to pull around him to take the lead by the end of the first lap.
Other than three cautions, caused by engine blow-ups for Ryan Hunter-Reay and Juan Pablo Montoya, and a spin by Max Chilton, no one could stop Newgarden.
Chip Ganassi Racing driver Scott Dixon made a late charge but came up short, eventually finishing in third behind Team Penske's Will Power.
Series points leader Pagenaud and Schmidt Peterson Motorsports' Mikhail Aleshin rounded out the top five, with the rest of the field unable to finish on the lead lap.
