Colton Herta

Colton Herta sat in the pits with a technical problem Saturday morning in the opening minutes of practice for the Firestone Grand Prix of St. Petersburg presented by RP Funding, but he overcame the gremlins to lead the session.

Herta turned a top lap of 1 minute, .1331 of a second in the No. 26 Gainbridge Honda fielded by Andretti Global. He spent the first few minutes of the 45-minute session with an apparent electrical problem in his car. Herta was eighth in Friday practice at 1:00.9937.
