Sebastien Bourdais raced to his first IndyCar victory of the season, beating Conor Daly by 2 seconds Saturday at Belle Isle.
Bourdais had not led a single lap in any of the season's first six races, and he hadn't finished higher than eighth. He led only 12 of the 70 laps Saturday on the 2.35-mile street course, but Bourdais was able to hold on the rest of the way after Daly made a pit stop on lap 61 and gave up the lead.
Bourdais won for the second time at Belle Isle. He took the latter half of last year's doubleheader at the Detroit course.
Indianapolis 500 winner Alexander Rossi finished 10th.
Bourdais won for the 35th time in his career.
