Due to a lack of budget, Baguette couldn't get a full-time seat for the 2011 IndyCar Series. However, he could find a deal with Bobby Rahal's team Rahal Letterman Lanigan Racing to enter the 2011 Indianapolis 500 with the n°30 car. After showing an impressive pace during practice, Baguette qualified on the fifth row for his second Indy 500. During the race, he was constantly positioned within the first half of the field and on lap 189, manage a pass on Danica Patrick to take the lead of the 2011 Indianapolis 500. The n° 30 race engineer gambled on the race strategy by extending his time out on track, hoping for a late yellow flag that would certainly have given the car a good shot for the win, but this didn't happen and low on fuel, Baguette had to pit three laps before the end of the race. He finished 7th, still his best result of his career.
