field fanned out five-wide. Andretti narrowly squeezed between Rick Mears and pole-sitter Emerson Fittipaldi and emerged with the lead in the chicane. Emerson Fittipaldi finished second. Andretti's only tense moment of the day came around the halfway point. He became mired behind the lapped car of Truesports driver Scott Pruett, which allowed Fittipaldi to close within a few seconds. Pruett, who qualified third and finished eight, had a decent run in the Truesports 91C chassis, holding off Andretti for many laps, but was noticeably down on power with the Judd AV engine. 1992: For the third year in a row, Michael Andretti won in dominating fashion. Andretti took the lead at the start and led 100 of 102 laps. It was Andretti's first win of the 1992 season, and the first Indy car victory for the new Ford Cosworth XB engine. The 1992 race saw changes to the race track. The chicane near the end of the mainstretch was removed, and replaced by the sharper and longer Festival Curves. 1993: Nigel Mansell started from the pole, and led the first 27 laps. In fierce battle with Emerson Fittipaldi, Mansell locked up the brakes on lap 28 going into the Festival Curves, and slid off-course into a row of cones and into the runoff area. Mansell kept the engine running, and re-joined the race, but Fittipaldi was now the leader. The skies opened up on lap 45, soaking the course, and forced the teams to switch to rain tires for the next 25-30 laps. Fittipaldi led 70 of the final 75 laps, and won for the second time at Portland. Mansell charged back to finish in second place. 1994: Team Penske swept the podium with Al Unser Jr. winning, Emerson Fittipaldi second, and Paul Tracy third. Unser grabbed the lead at the start and led 96 laps en route to victory. Unser made his final pit stop on lap 69. Fittipaldi made his stop one lap later, and for a moment appeared that he would emerge as the leader. Unser on warmer tires, passed Fittipaldi coming out of the Festival Curves, and led the rest of the way. 1995: Al Unser Jr. dominated the race, leading 76 of the 102 laps, and beat second place Jimmy Vasser by over 28 seconds. However, Unser's car failed post-race inspection due to insufficient ground clearance. Unser was stripped of the victory, and Jimmy Vasser
