DETROIT -- Joao Barbosa passed teammate David Donohue with 18 laps left and went on to win the Grand-Am Detroit 200 at Belle Isle on Saturday.
The Portuguese driver earned his first win of the season and No. 8 for his career in the series, co-driving with Darren Law. Donohue was second, just .440 seconds behind. Scott Pruett finished third, co-driving in the 2-hour race with Memo Rojas.
Barbosa avoided trouble, unlike competitors such as Ricky Taylor, who won the last two Grand-Am events. Taylor pitted to give up the lead nearing the midway mark of the race and hit a retaining wall at the pit-road exit.
Taylor won in the Grand Touring class, Jonathan Bomarito finished second and Robin Liddell third.
