Andretti Autosport confirmed today that Dalton Kellett has joined its Mazda Road to Indy roster. The 21-year-old will drive the No. 28 K-Line machine for the Indianapolis-based team for his sophomore season in the Pro Mazda Championship presented by Cooper Tires.

The Juncos Racing Pro Mazda driver lineup is beginning to take shape with the return of José Gutiérrez competing in the 2015 Pro Mazda Championship Presented by Cooper Tires. Gutiérrez rejoins the team after a successful rookie season where he helped Juncos Racing win the 2014 Pro Mazda Team Championship.

Juncos Racing completed the 2014 Chris Griffis Mazda Road to Indy Memorial Test with four drivers running in the Pro Mazda sessions this past weekend at the Indianapolis Motor Speedway. Rookie drivers Timothé Buret and Austin Cindric turned their first laps in the Pro Mazda car alongside veteran drivers José Gutiérrez and Garett Grist with team Juncos Racing.

The 2014 race season may be over, but that didn’t mean it was time for Rising Star Racing drivers Josef Newgarden, Spencer Pigot and Neil Alberico to hang up their helmets just yet. Just a few weeks after the end to a stellar season for all three drivers, including a Pro Mazda Championship title for Pigot, the three were back in race mode over the weekend testing at the Indianapolis Motor Speedway.

Team Pelfrey carried its strong form from this year’s Pro Mazda Championship Presented by Cooper Tires into this past weekend’s Chris Griffis Memorial Mazda Road to Indy Open Test at the Indianapolis Motor Speedway Grand Prix road course. Three young drivers chose to “test the Pro Mazda waters” with Team Pelfrey in preparation for potential campaigns in 2015, with 15-year-old Mexican talent Patricio O’Ward stunning onlookers by posting the fastest lap of all. USF2000 graduate Peter Portante, from Plainville, Conn., and Team Pelfrey F1600 regular Augie Lerch, from Tucson, Ariz., also impressed during the test.
