The 1989 Indianapolis 500 saw one of the classic late-race duels in the first 100 years of the race. Emerson Fittipaldi, driving a Penske PC18 for Pat Patrick, dominated the race, but was reeled in by Al Unser Junior in the races final fifteen laps. With five laps to go, Unser passed Fittipaldi for the lead. Fittipaldi hung close to Unser, and as the two started the 199th lap, they started to encounter traffic. Going down the back straight, Fittipaldi pulled out to pass Unser, who pulled out to pass a lapped car. They both pinched the entrance to turn three - the shallow entry caused Fittipaldi to get lose and the back of his car slid into Unser's car causing him to crash into the turn 3 wall. Fittipaldi recovered to take the white flag and find Unser - on the final lap of the race, giving Fittipaldi the thumbs up as he went on to win his first Indianapolis 500.
