IndyCar has fined Marco Andretti $2,500 for failing to heed to an order from race control during Saturday's race at the Grand Prix of Houston.

Andretti ignored a blue flag to give way to leader Takuma Sato as Andretti tried to stay on the lead lap. Race control could have perceived that Andretti was holding up Sato to allow Andretti Autosport teammate James Hinchcliffe to catch the leader.

Because Andretti ignored the blue flag, he was given a black flag and a drive-thru penalty.

In addition to the fine, IndyCar placed Andretti on probation for three races beginning with Sunday's race. Andretti Autosport was also fined $2,500.
