The drivers on the starting grid for the Star Mazda Championship double-header at the Grand Prix of Baltimore are racing for a champion's prize valued in excess of $600,000 and represent an intriguing mix of Baltimore veterans like Sage Karam, Gustavo Menezes, Jerimy Daniel, Connor De Phillippi and Carlos Linares and brash young hotshoes like Jack Hawksworth (the current championship leader with six wins), Gabby Chaves, Petri Suvanto and the series lone female driver, Ashley Freiberg.

Second year driver Sage Karam, racing the No. 88 Andretti Autosport / Comfort Revolution Mazda, finished second here last year and went on to win the 'Rookie of the Year' award; he has won two races this year, scored eight podium finishes and sits second in the championship. And, having won Race 2 on the GP3R street circuit in Trois-Rivières three weeks ago, he comes to Baltimore with a winner's momentum.

Menezes, driver of the No. 83 Team Pelfrey / SafetyPark / Oakley Mazda, is eighth in the championship this year with eight top-10 finishes and is planning to make his Firestone Indy Lights debut at the series’ season finale in Fontana, Calif. Quebec racer Jerimy Daniel, driving the No. 10 The Racing Company / FixAuto / Sherwin-Williams Mazda for his family-owned team, The Racing Company, finished fifth last year and is back, counting on experience to produce a podium.

The final two drivers represent opposite ends of the spectrum; Californian Connor De Phillippi came into this race last year second in the championship with three wins, but bad luck consigned him to a 9th-place finish. He re-bounded to win the season finale from the pole at Mazda Raceway, but still finished 2nd in the championship. This season, driving for a different team, he won from the pole racing the No. 2 Juncos Racing / ModSpace Racing / One24 Mazda in Race 1 at the series' season-opener at St. Petersburg, and scored another convincing win from the pole on at the Night Before the 500 on the Lucas Oil Raceway oval in Indianapolis. But, through a combination of bad luck, bad timing and being in the wrong place at the wrong time, De Phillippi's season has come to a crossroads with three finishes outside the top-10 in the last five races.

Venezuelan driver Carlos Linares finished 10th here last year, and seventh in the championship, but this year, with his team expanded to two cars and sharing technical data and expertise with Team GDT, Linares racing experienced its first-ever victory when Camilo Schmidt, a top-level Venezuelan kart racer now driving the No. 21 Linares Racing Mazda, scored a surprise - but well-deserved - victory in the wet during Race 1 at Edmonton. Having proved the team can win, it must now prove that Edmonton was no fluke.

Making hash of the idea of experience providing an advantage is rookie English racer Jack Hawksworth, a top European kart racer who only made the jump to open-wheel cars in 2011. In his first-ever season of Star Mazda competition, he leads the championship with six wins, eight poles and ten fastest race laps. A pair of crashes, one due to a mechanical malfunction on the Iowa Oval and a mistake in the rain during Race 2 at Trois-Rivieres (after winning Race 1), have whittled down his points lead to 41 over Sage Karam. As a result, despite his dominant performance so far, with a maximum of 62 points up for grabs this weekend, and 155 left during the season, the championship battle is far from over and he will need to maintain a laser-focus in Baltimore and the remaining races.

Another rookie making waves in the Star Mazda driver pool this season is Colombian racer Gabriel 'Gabby' Chaves. With experience in European open-wheel ladder series, and membership in the prestigious FIA Institute Young Driver Excellence Academy, his 'fast but steady' approach to the season driving the No. 19 JDC Motorsports / CLARO / Marca Colombia / Tecpro Mazda has resulted in six podium finishes, and eleven top-5s, placing him third in the championship... well within striking distance if he can break through the 'podium ceiling' and win some races.

Mixing both rookie status and experience at Baltimore is Finnish racer Petri Suvanto, driver of the No. 81 Team Pelfrey / Mazda Road to Indy Mazda. Currently 6th in the championship with three podium finishes and six top-5s, Suvanto was the 2011 USF2000 champion and is racing in Star Mazda this season with scholarship funding from the Mazda Road to Indy. In the USF2000 race at Baltimore last year he finished 2nd in both Race 1 and Race 2, so although driving a different, faster car this year, he knows the track well and is hungry to score his first win.

 Other contenders worth watching include Chilean racer Martin Scuncio in the No. 22 Juncos Racing / Pullman Bus / Gobierno Regional del Bio-Biol Mazda; he has one win so far this season and is 6th in the championship. Colombian driver Juan Piedrahita has had an up-and-down season in his No. 9 JDC Motorsports / Petrosur / Colombia es pasion / GFK Motors / Lamd Link Mazda, but still sits 7th in the championship with two podiums, five top-5s and ten top-10s.

Star Mazda on-track action at the Indy Grand Prix of Baltimore begins with a 30 minute practice session from 8:40 -- 9:10 am Friday, August 31, followed by qualifying for the PEAK Performance pole for Saturday's Race 1 from 1:55 pm -- 2:25 pm.
