Bump Day is known for providing tension and drama, but rarely has it delivered either to quite the degree it did this year. At one point it looked as though the series' biggest name - Danica Patrick - wasn't going to make it into the field; and then later, Andretti Autosport team mates were pitched against each other, with drivers making qualifying runs knowing that if they succeeded then it would cost their team mate their Indy 500 place.
It started on schedule at noon, with the field already thinned by two drivers after the announcement that Dragon Racing had withdrawn, after their second car had been wrecked in morning practice leaving them with no viable hardware to run. There was also confirmation that Sarah Fisher had no intention of putting anyone in the #57 car that they had entered, which was another potential rival for an Indy 500 grid slot removed.
That was good news to the 14 drivers still left hunting one of the remaining nine grid positions not filled on Saturday, Pole Day. But it still meant that five drivers were going to be packing up and leaving Indianapolis early when qualifying finished at the sound of a gunshot at 6pm local time.
First to go out was Dreyer & Reinbold's Ana Beatriz followed by Ganassi junior team driver Graham Rahal, who duly completed their qualifying attempts and claimed the first two remaining nine positions on the grid.
But before the next car in the line - AFS' Raphael Matos - could head out, a violent thunderstorm swept in and unloaded a huge quantity of water onto the Indianapolis Motor Speedway, as the crowds, teams and drivers all dived for cover and the power momentarily failed in the media centre. The storm was brief, but it left the track flooded and it took a long time for the IMS staff to get things cleaned up and ready for more qualifying runs; all the while, anxious eyes turned skywards as more showers kept bubbling up and passing close by the Speedway, anyone of which could set back the clear-up efforts.
Two hours later, the track was dry enough for qualifying efforts to resume, and for 45 minutes the cars were able to run qualification attempts: Matos first then Ryan Briscoe (still struggling in the backup car he'd been forced into after wrecking his main car on Saturday morning), Alex Lloyd, Pippa Mann, Charlie Kimball, Ryan Hunter-Reay and Mike Conway. Once those nine had set times, the grid was effectively filled with 33 cars - everything that followed was to be a bumping attempt.
More significantly, all the times set on Sunday were slower than the times set the previous day, thanks to the changing conditions and the thorough wash that the track had received wiping it clean of the rubber that he been laid down that had been aiding grip up until then. It meant that no one from 24th place up was in any danger of being bumped - Simona de Silvestro, who had qualified in 24th, could breath easy. The battle would be a purely Bump Day affair.
First up was the Dale Coyne Racing rookie James Jakes, who has been consistently one of the slowest people throughout the week of practice and qualifying. He didn't disappoint, and his time failed to dislodge the driver on the bubble who was Raphael Matos. Next up was Conquest's Sebastian Saavedra, another driver who had been set back by the loss of so much practice time because of the weather in the past week, and consequently never threatened to make it onto the grid.
Marco Andretti was next up, and he was the first driver fast enough to 'bump' his way onto the grid this year: his average speed of 223.688mph was enough to displace Matos - who would now have to run again - and put Andretti's team mate Mike Conway on the bubble. Sure enough, Conway was bumped by the next runner who was Dreyer & Reinbold's Paul Tracy who managed a 224.939mph - the fastest lap of the afternoon.
