Oli Webb has continued his strong season as the Firestone Indy Lights championship returned to the USA for the penultimate round following three rounds in Canada.

Rookie Webb’s run of point-scoring form carried on as he took the chequered flag in sixth place.

Former Ryles Park pupil Webb returned to the familiar territory of Baltimore, having raced there in last year’s championship, and was quickly up to speed, showing early potential on a tricky, bumpy circuit.

However, the 21-year-old’s first practice session was brought to a premature end after four laps, when the organisers made safety-induced changes to the track.

Despite an additional chicane being introduced, Webb continued to show consistent pace as he got to grips with the revised layout.

While Webb was trading times with Sam Schmidt Motorsport team-mate Esteban Guerrieri, the leaders started a final flying lap attempt, and an incident at the new chicane saw a caution, and a red flag, which brought the session to a premature end.

Webb was therefore unable to respond to quicker laps posted by the session’s earlier drivers and he began the race fifth on the grid.

A good start saw him move up the field and vying for second alongside Guerieri. But turn one saw him on the outside line, on the dusty part of the hairpin, and a collision after a daring move from Gustavo Yacaman down the inside caused a knock-on effect and Webb’s car bore the brunt of it, with a broken front wing.

Webb continued to push despite the damaged wing and worked hard to chase down the leading pack.

A spirited drive saw him recover to fourth in the closing stages, but the reduced levels of downforce saw him run wide, crossing the line in a hard-fought sixth place.

SSM team-mate Tristan Vautier claimed the race victory, and now leads the championship.

Webb said: "This is an extremely physical circuit. The bumpy surface makes it particularly tricky, and I am pleased to take points away from the weekend."

Webb now sits seventh overall in the driver championship and is third-placed rookie.
