BROWNSBURG, Ind. -- Weiron Tan led every inch of the 90-lap Cooper Tires Freedom 90 around the 0.686-mile Lucas Oil Raceway oval, but his eventual margin of victory was a mere 0.4261 seconds over Will Owen of Juncos Racing. It was the third win in succession at Lucas Oil Raceway for Andretti Autosport.

Neil Alberico fought his way from sixth on the opening lap to third for Cape Motorsports with Wayne Taylor Racing. With the result the Californian thereby closed to within eight points of championship leader Santi Urrutia of Team Pelfrey, whose day ended early after clipping the Turn 3 wall.

Tan, who qualified on the pole for the fifth time this season, led from the outset and teammate Dalton Kellett tucked in to second place, only for his car to snap sideways between Turns 3 and 4 on the opening lap. The Canadian did well to maintain control, but not before losing several positions.

Owen took advantage of Kellett's slide to sneak past Florian Latorre (Cape Motorsports) for second, while fellow Canadian Daniel Burkett squeezed ahead of Cape teammate Alberico in fourth. Garett Grist (Juncos Racing) ran sixth ahead of the unfortunate Kellett, who was later involved in an incident with Timothe Buret (Juncos Racing) in Turn 3 on Lap 28. Raoul Owens (Team Pelfrey) also was caught up in the skirmish.

Tan's commanding five-second lead was erased by the ensuing full-course caution, although the 20-year-old quickly re-established his advantage over Owen at the restart.

A thrilling final few laps ended with Grist holding onto fourth ahead of Juncos Racing's Jose Gutierrez, who earned the Quartermaster Hard Charger Award for advancing six positions over his grid placing. Owen, meanwhile, closed right up onto Tan's tail but was unable to make a challenge for the lead and had to settle for second for the second race in a row.

"That was a really incredible race," Tan said. "We made a good start and pushed on from there with very consistent times. We pulled quite a big gap before the caution came out. Once it went green, it was just a matter of being consistent, to not force myself to make any mistakes, to make clean passes on traffic and finish the race. I was really hoping for the race to finish.

"The Andretti team gave me a really good race car; we've been fast since we got here. This will help me in the championship, since every bit helps, and now we look forward to Toronto. We need to score some really good points and hope the championship comes to us."
