Sam Schmidt Motorsports’ Esteban Guerrieri led flag-to-flag to win Sunday’s Firestone Indy Lights’ Grand Prix of Trois-Rivieres in Montreal, Canada.

Driving the No. 7 Lucas Oil car, Guerrieri held off several attacks from behind and battled Mother Nature to win his third race of the year in heavy rain. Team Moore Racing’s Gustavo Yacaman followed Guerrieri across the finish line in second.

“It was a very tough race,” Guerrieri said. “When it started to rain, it got a bit crazy, then the red flag came out and it was a whole new race.”

Guerrieri’s Trois-Rivieres victory adds to his win on The Milwaukee Mile in June and his win in Edmonton, Alberta two weeks ago. The Argentinian also has six Sunoco Pole Awards in 2011 including the Trois-Rivieres pole. His qualifying lap on Saturday of 57.4541 seconds at 94.615 mph is also a new official track record for Trois Rivieres.

SSM driver Josef Newgarden, in the No. 11 Copart/Score Big/Robo-Pong car, finished third after starting fourth. He remains the Firestone Indy Lights points leader with 396. Guerrieri is second with 351.

Rounding out the top five were Andretti Autosports Stefan Wilson and Patrick Dempsey.

Driving the No. 3 Nevoni car for Sam Schmidt Motorsports, Brazilian Victor Carbone finished tenth after starting eighth.

In his return to the cockpit of the No. 77 Mazda Road To Indy car for SSM, Conor Daly had a shot at victory before spinning while attempting to pass Guerrieri late in the race. After starting second, Daly finished 13th.  

Carbone is ninth in points with 225, while Daly is 12th with 126 points after having only competed in four races.

There were two caution periods for seven laps.

The next Firestone Indy Lights Series race is the New Hampshire 100, Sunday, August 14 at the New Hampshire Motor Speedway in Loudon, New Hampshire.
