The first practice for the Grand Prix of Alabama was another strong showing for the Andretti team, with Marcus Ericsson the fastest and Colton Herta third. Alex Palou and Team Penske are not far behind, and the way qualifying groups fall could determine how everything shakes out.

Team Penske put all three cars in the top 10. Will Power led the team in fourth.

The X factor tomorrow will be the weather. Rain is expected at times Saturday, and is likely during IndyCar qualifying.
