PRE-RACE
The morning warmup session was rather action-packed. Chip Ganassi Racing's sophomore driver Marcus Armstrong topped the time charts as the only driver to lay down a lap time in the one minute, nine second range.
Pole-sitter Alex Palou was fourth quickest in the morning warmup.
A bit of drama between Santino Ferrucci and Romain Grosjean stirred up some controversy on track. During an install lap, Ferrucci tailgated Grosjean on the pit lane and the two ran near each other until the two exited turn 10.
Grosjean attempted to pass Ferrucci, but did not appear to give Ferrucci enough room. Ferrucci kept his foot in the gas and pushed Grosjean's No. 78 up the race track. Ferrucci was then seen on a replay giving Grosjean an obscene hand gesture.
Ferrucci told the television broadcast Grosjean drove into him during the morning warmup during the previous race weekend at Barber Motorsports Park.
"It's not Formula 1 anymore," said Ferrucci to NBC Sports. "You wanna turn into me when I have the inside? I'm not lifting."
Ferrucci clarified he "didn't have a beef" with Grosjean, but was frustrated with the way he has been raced recently by the Frenchman.
Meanwhile, disaster struck for fifth-place qualifier Pato O'Ward. The Chevrolet engine in his No. 5 Arrow McLaren machine gave up in the morning warmup, forcing the team to change the engine.
According to 13Sports director Dave Calabro, the engine O'Ward blew was an old engine. Mechanics worked tirelessly to install a brand new Chevrolet power unit just three and a half hours prior to the start of the race.
