The Andretti Autosport driver stormed through the field from 14th on the grid to finish third, his first podium of the season despite starting the last two races from pole position.
“It's been really good,” he said of his pace in recent events. “It's a little embarrassing it took this long.
“We've had good cars all year, and just whatever has happened. It's great to finally get that monkey off our back.
“Hopefully we can continue this and go right back to having strong performances in qualifying and that just makes you race so much easier when you are able to race at the front, and the results come a lot easier at that point.
“We'll dial in on that for the next race, and hopefully have two good ones at Iowa [this weekend].”
Last October, Herta signed a four-year contract extension that is believed to be the most lucrative in the IndyCar paddock – and also opens the possibility for him to graduate to Formula 1 if the team gets an entry.
