ST. PETERSBURG, Fla.>> Scott Dixon ran the entire IndyCar season-opening race without radio communication in a miscue that probably cost him his first career victory on the downtown streets of St. Petersburg.

The six-time IndyCar champion finished second to winner Alex Palou in a 1-2 finish for Chip Ganassi Racing on Sunday. Team owner Ganassi said if the radio had not malfunctioned “he would have won — it was simple.”

Dixon instead was runner-up at St. Pete for the fifth time in 21 starts on the street course. He has eight career podiums but has never reached the top spot.

“I’m pretty pissed off. We had a good race going and we didn’t get it done, so it doesn’t feel good, that’s for sure,” fumed the New Zealander.

Dixon said it’s the first time in his career he ran an entire race without radio communications and he lost already spotty contact with the No. 9 crew around the 10th lap for good. He pitted based on his fuel gauge but not having the radio “ultimately cost us the race.”

Ganassi said the team could intermittently hear Dixon but Dixon could not hear them. The lack of communication caused Dixon to pit a lap too late for fuel and it cost him the victory.
