As the Mazda Road to Indy series compete this weekend on the Indianapolis Motor Speedway road course, perhaps it is appropriate that Americans hold the points lead in all three championships.

Spencer Pigot of Orlando, Fla., took control of the Indy Lights Presented by Cooper Tires title chase by virtue of a commanding double victory at Barber Motorsports Park in Birmingham, Ala. Neil Alberico, from Los Gatos, Calif., furthered his claim to the Pro Mazda Championship Presented by Cooper Tires by winning also at Barber, while Jake Eidson, from Littleton, Colo., heads the Cooper Tires USF2000 Championship Powered by Mazda standings on the heels of podium finishes in each of the six races held to date.

Pigot aims ton cement his authority at Indy

Pigot, driving for Juncos Racing, finished a strong third in the first two races of the season at St. Petersburg, Fla. He impressed again at Long Beach, rising to second after being relegated to fifth from his front-row starting position while avoiding an incident at Turn 1. One week later at Barber he won both races from the pole. The wins enabled 21-year-old Pigot to grasp the points lead from Ed Jones, who, along with the European open-wheel powerhouse Carlin team, had begun his North American career in style with three consecutive victories.

Jones, 20, has every intention of working his way back to the front at Indianapolis, along with teammate and ex-F1 driver Max Chilton, who claimed his first podium result last time out in Alabama.

Fellow Englishman Jack Harvey also is sure to be a prominent force for seven-time Indy Lights championship-winning team Schmidt Peterson Motorsports with Curb-Agajanian. The former British Formula 3 champion finished second in the 2014 Indy Lights championship, losing out only on a tie-breaker of second-place finishes, and has finished second again in four of the five races run so far this season. Harvey, who finished on the podium in both races on the Indy road course last year, is now aiming for the top step.

Rookies Felix Serralles (Belardi Auto Racing), from Ponce, Puerto Rico, and RC Enerson (Schmidt Peterson), from New Port Richey, Fla., already have podium finishes to their credit this year.

Cooper Tires Prototype Lites Championship Powered by Mazda title-winner Sean Rayhall, from Winston, Ga., made an impressive Indy Lights debut at Barber for 8Star Motorsports.

Alberico and Urrutia head Pro Mazda field

The Pro Mazda competitors will contest a tripleheader, including a make-up race following postponement of the scheduled second race last month at NOLA Motorsports Park in Louisiana due to severe weather.

Alberico, who finished a strong third in his rookie campaign in 2014, romped to a pair of victories on the streets of St. Petersburg to claim the early championship lead. The team struggled for pace at NOLA, where Alberico finished sixth, but bounced back two weeks ago at Barber Motorsports Park to claim a fourth and another race win, which allowed him to maintain an eight-point lead as the expanded 22-car field heads to Indy. Alberico, in particular, is looking forward to his return to Indianapolis after securing two podium finishes last year.

The next five positions in the points table currently are held by Pro Mazda rookies, headed by the Team Pelfrey pair of Santiago Urrutia, from Uruguay, and Patricio O'Ward from Monterrey, Mexico, but now is based and attends school in San Antonio, Texas.

Urrutia won at NOLA and has added three more podium finishes. O'Ward, with three top-five finishes, heads a group of five drivers who are separated by just six points: Florian Latorre (Cape Motorsports), who won the 2014 USF2000 championship; Timothe Buret (Juncos Racing), who took a second at Barber; Weiron Tan (Andretti Autosport), the pole sitter at NOLA and winner of Race One at Barber; and Garett Grist (Juncos Racing), who won twice during his rookie campaign in 2014.

Jose Gutierrez (Juncos Racing), from Monterrey, Mexico, and Daniel Burkett (Cape Motorsports), from Winnipeg, Manitoba, also have podium finishes.

Added to the lineup for the races this weekend is Scott Hargrove, who won the 2013 USF2000 championship and finished a close second in the 2014 Pro Mazda title chase, including a pair of wins at Indianapolis, with JDC MotorSports. Also, USF2000 race winner Victor Franzoni will make his debut with M1 Racing.

Consistent pace the key for USF2000 points leader

Eidson, a champion in both the Skip Barber Racing Series and the F1600 Championship Series, won the opening two races of the season on the streets of St. Petersburg, Fla., and since then has notched a quartet of third-place finishes to ensure he holds the series points lead prior to the two 30-minute races.

The Cape Motorsports with Wayne Taylor Racing pair of Nico Jamin, from Rouen, France, and Aaron Telitz, from Birchwood, Wis., have combined to win three of the past four races. They trail Eidson by 11 and 21 points, respectively.

Fourth place in the standings is held by Anthony Martin, from Perth, Western Australia. Fellow rookie Parker Thompson, from Red Deer, Alberta, also has impressed with three top-five finishes for JDC MotorSports.

Others to watch this week include another young Australian, Luke Gabin (Team Pelfrey) and Noblesville, Ind., native Sam Chastain, who is making his USF2000 debut with JDC MotorSports after showing well in last year's F1600 Championship series.
