Simon Pagenaud and Josef Newgarden ensured that three of the four Penske cars made it into Sunday's final qualifying session, while Ed Jones impressed to end the day fifth on the charts.
Herta, who will be the only rookie to take part in the Fast Nine, set another timed lap in the final hour to jump up to fifth, despite already looking safe in the top nine,
Ed Jones was sixth, marginally behind Herta with an average speed of 229.440.
However, Jones was ahead of his employee Ed Carpenter, who started last year's Indy 500 from pole position, and he will have another shot at the feat on Sunday, as he ended the day in sixth.
Alexander Rossi was seventh, ahead of Sebastian Bourdais was ninth, as he bet Marco Andretti to the final spot for tomorrow's qualifying session.
As he was last year, James Hinchcliffe will be fighting not to be bumped from starting the race on Sunday.
The Canadian's day was hampered when he had a major crash during his one guaranteed lap, which forced Schmidt Peterson Motorsports to revert to the spare car.
After making it back out onto the circuit, Hinchcliffe couldn't set a good enough lap, and ill be battling for the final row tomorrow.
Fernando Alonso had a tough day at the Indy 500 qualifying, as he failed to make the top 30. He will now face Sunday's bump, where those outside the top 30 fight for the last three positions on the grid.
The two-time Formula 1 world champion suffered a puncture on his first attempt, but then could not find much pace in McLaren's spare #66 car, which he is driving after his crash in practice.
Alonso ran a total of five times throughout the session, and it was his third run before he made the top 30 for the first time. Then after deciding to remove his own time in order to quickly run again, his next attempt was much slower and the Spaniard decided to back off.
On his final attempt, it was hit or miss as to whether he would earn a guaranteed race start. He was safe up until a last-ditch attempt by JR Hilderbrand pushed him down the order with no time to have another go.
While Alonso didn't make the top thirty, Pippa Mann got through, sparking tears of joy following her bump from qualifying 12 months ago.
