1991: Michael leads 97 laps, later saying in 2011, "I really didn't think that anybody had anything for me at that point. I was ready to put Rick a lap down and his day would have been over, and I get a flat tire, so I had to come into the pits right away, and that's the thing that changed the race." With 18 laps to go, he leads Rick Mears by 15 seconds, but needs to make one final pit stop for fuel. A timely caution flag flies and he loses minimal ground as he pits under the yellow. On the ensuing restart with 13 laps to go, he makes a daring pass on the outside in turn one to grab the lead from Mears. On the very next lap, Mears steals the thunder as he makes exactly the same counter-move and quickly pulls out to a lead. Moments later, Michael's father Mario suddenly coasts to a stop at the entrance to the pits. The yellow flag flies again, and bunches up the field. Many accused Mario of stopping on purpose in a ploy to aid his son. Whatever the case, the point was moot as Mears, driving for car owner Roger Penske, pulls away to the victory. Michael settled for second, later saying in 2011, "I really thought that we had it cause we had dominated the race and I still til this day don't understand where Rick got that speed." This race was the first to feature four Andrettis, (Mario, Michael, Jeff, and John). Michael went on to win the 1991 CART championship.
