Antinucci finished 19th in the Camping World Grand Prix at The Glen on July 5 – his IndyCar Series debut for the first-year IndyCar Series team. Antinucci, 28, won at Watkins Glen International in 2008 on the way to a runner-up finish in the Firestone Indy Lights championship.
"I am really excited to be working with Team 3G again for the Canadian events," said Antinucci, who lives in San Diego. "This is a young team made up of very experienced guys who are just as passionate about competing as I am. We are working hard to hopefully build a long-term program together. I would love to keep driving for these guys."
After pitting for the first time on Lap 17, Antinucci was running 13th. But two laps later, a front upright failure on the No. 98 car caused it to spin off the track in Turn 1. Repairs were made and he returned to complete the 60-lap race.
"Although we aren't able to claim a stunning top three or a glittering top five to reward our effort, I feel happy about myself and the way the team has worked this July 4 weekend," Antinucci said.
Added team co-owner Steve Sudler: "We have had numerous meetings with potential sponsors for 2010 and Richard would be a great fit for many of them. As we look towards building this team for the long term, we feel that Richard will be a great asset to our marketing partners."
