"I was quick in the wet and soon as it started to dry out we pitted for slicks at just the right time and it was the right choice," said Wilson, the younger brother of IndyCar Series driver Justin Wilson. "We were really quick straight away when we exited the pits and were probably the fastest car on the track. Obviously we'd like the podium but James (Hinchcliffe) did a great job and the two Andretti Green cars did really well so it was getting pretty hard to catch them so I'm pretty pleased."
But Wilson nearly didn't make it to fourth place. Part of his seat slipped forcing him to drive for several laps around the tricky 1.755-mile circuit with one hand.
"There's three parts to the seat, and one of the parts came loose, actually," Wilson said. "Going in to Turn 9, it fell forward and jammed my right hand up in the air, so I was going through all this last sequence with one hand. So it pretty much slowed me down so I had to get rid of it and lose it on track.
"There was no way I was going to catch Hinch (Hinchcliffe) so I just preserved and kept my fourth place my best finish all year."
