BALTIMORE -- Jack Hawksworth has won two of the three street course races, and a victory in the Grand Prix of Baltimore would go a long way in the 2012 Pro Mazda champion get back in the thick of the Firestone Indy Lights championship chase.

Hawksworth finished third in the last race -- at Mid-Ohio on Aug. 4 -- and is 40 points behind Munoz. Sage Karam is third (16 points back).

"We didn’t want to get too far away from what we know works; we were pretty comfortable with the car straight off the truck," Hawksworth said. "There’s just so many tricks to this place. It’s so bumpy, there’s a lot of different asphalt and stuff, so you’re kind of tuning the car around the different aspects of the circuit. We just tweaked things and kind of massaged the car a bit.

"Now we’ll go back and share what we’ve done and work overnight. It’s great to have a break now in between today and tomorrow because there’s a lot of information to look at and a lot of things to think about before we go stick on the line in qualifying."
