Takuma Sato claimed his first IndyCar victory in a chaotic race around the streets of Long Beach.
Sato ran among the frontrunners throughout the afternoon, and moved into the lead as the field cycled through its pitstops during a caution period on lap 31.
From there, both he and his team were flawless – Sato was quick when he needed to be, looked after his tyres, enjoyed perfect service in the pits, and never appeared to have any problems managing the gap between himself and his pursuers.
He crossed the finish line under full-course yellows following a late crash between Tony Kanaan and Oriol Servia, but just prior to the crash he had a 5.2s lead over Graham Rahal, so the yellow made little difference.
Rahal had matched Sato’s pace early in the final stint before backing off in the hope of saving enough fuel to attack Sato at the end, but Sato had enough in reserve himself to keep him at a distance.
Nevertheless, it was a good result for Rahal following a disappointing start to the season.
Justin Wilson did a superb job to finish third after starting from the rear of the field, the Brit making good use of the extra set of red tyres that he had available after not completing a lap in qualifying yesterday.
Polesitter Dario Franchitti was fourth, the Scot having lost time to a slow first pitstop.
He was followed across the line by Servia, who’d been able to continue running after the clash that left Kanaan stuck against the barrier, but a post-race penalty for avoidable contact tumbled the Spaniard down the order and promoted JR Hildebrand to fifth place.
Elsewhere, there was chaos. Scott Dixon, who started from the back of the field, was spun around early on by Tristan Vautier, sending the Kiwi into the pits to have a puncture repaired and Vautier in for a penalty.
Dixon fell a lap down, but later regained it and finished 10th.
Vautier meanwhile recovered to run as high as third late on before being issued yet another penalty, this time as the result of being released directly into the side of Will Power’s car during a stop.
The resultant contact sent Power back into the pits on the next lap for minor repairs, compounding an already frustrating afternoon for the Penske driver, who had struggled badly on his primary tyres during the middle phase of the race.
His team-mates fared little better, with Helio Castroneves falling out of contention early after damaging his front wing, and AJ Allmendinger retiring with a mechanical problem.
Things were just as tough at Andretti, with James Hinchcliffe being squeezed into the wall and crashing out on a restart – an incident that also damaged the car of team-mate EJ Viso – and Ryan Hunter-Reay crashing while trying to pass Ana Beatriz.
