Jack Hawksworth scored a comfortable Indy Lights win around the streets of Baltimore.
From pole position the Briton led every lap. The race ran under yellows on two occasions, and the restarts were the only time the Sam Schmidt driver was under any pressure. He resisted this with ease to claim his third win of the season and bolster his championship hopes with two races to go.
Sage Karam made a great start from fourth, and while he managed a good run on Hawksworth on the first restart, he spent the first part of the second leg fending off Gabby Chaves in a Schmidt 1-2-3. Second has given Karam the points lead.
Chaves was well clear of Irishman Peter Dempsey, but it was a poor race for title hopeful Carlos Munoz, who crashed out. The Andretti Autosport driver suspected a brake failure to have caused the accident that cost him the points lead.
"I don't really know what happened," said Munoz. "I just braked and needed the car just to stop for the wall. I'm not sure if the car broke or just snapped.
"What can I say? We still have two races to go. Everyone in the championship is really close from each other, but that's another thing we expect. I have to go racing these last two races."
