A good passing move by Gustavo Yacaman earned the Colombian the Indy Lights win in this weekend's race in Detroit.
The Colombian, who started from sixth on the grid for Team Moore Racing, worked his way steadily into contention during the early stages of the race, and then spent several laps stalking polesitter Oliver Webb before seizing the lead with an over-and-under move two thirds of the way through the race.
Webb relinquished another position not long afterwards when Andretti Autosport rookie Carlos Munoz passed him around the outside to claim second place, leaving the Briton to settle for third in Sam Schmidt Motorsports' lead car.
The race switched from a lap race to a timed race following a lengthy spell under yellows triggered by Younessi Racing's Peter Dempsey, who crashed heavily while chasing Victor Carbone for second on lap 13. The Irishman pinballed from the outside barrier to the inside before skidding through a wall of tires and finally coming to rest. He extracted himself from the wreckage unassisted.
Carbone ended the race in fourth ahead of Schmidt team-mates Tristan Vautier and Esteban Guerrieri, the latter having dropped several places early on and then gambled on a pit stop for new tires during the caution.
