Herta lapped the 1.8-mile, 14-turn street circuit in his Honda-powered machine in 1m00.1331s, recording the fastest time of the weekend so far.
This was a regular format session after yesterday’s trial of quickfire multiple split-format sessions, with all cars running throughout the 45 minutes this time.
Kyle Kirkwood set the early pace for Andretti Global with a 1m00.6821s, 0.0651s ahead of the Penske-run machines of Scott McLaughlin and Will Power.
Power, who is suffering from pollen allergies this weekend, then took P1 with 1m00.4101s.
Rinus VeeKay leapt to second place after 15 minutes had elapsed in his Ed Carpenter Racing entry to make it a Chevrolet-powered 1-2, two tenths off Power’s pace.
Newgarden produced 1m00.3872s with a third of the session to go to set the fastest time, 0.05s off Friday’s pacesetter Felix Rosenqvist for Meyer Shank Racing.
Herta then beat that with 1m00.1331s, setting the fastest time of the weekend so far by a quarter of a second. “It was good to feel the car and get set for qualifying,” said Herta.
