Mike Conway won the first of two races at the Detroit Grand Prix, showing he's well suited for road racing after deciding he's uncomfortable on ovals.

The English driver finished nearly 13 seconds ahead of Ryan Hunter-Reay on Saturday to easily win the 70-lap race on the 2.36-mile Belle Isle street course.

Conway's Dale Coyne Racing teammate, Justin Wilson, was third, Scott Dixon was fourth and Helio Castroneves fifth.

IndyCar is running a second, full-length race in the same weekend for the first time Sunday when Conway will start up front for the first time in his career.

Dale Coyne Racing picked Conway to drive this weekend. In Conway's only other race this year, he qualified fifth and finished 25th at Long Beach for Bobby Rahal.
