Haas' hopes of scoring its best-ever Formula One result at the Australian Grand Prix were ended by two separate human errors, according to team boss Guenther Steiner.
Having started on the third row of the grid, Kevin Magnussen and Romain Grosjean were running fourth and fifth as they approached the first pit-stop window at the end of the first stint. After Magnussen made his planned pit stop, the Danish driver immediately slowed on his out-lap and stopped at Turn 4 -- it soon became clear the left rear tyre was not fitted correctly to his car. The following lap, Grosjean pitted and then slowed to a halt at Turn 2, with his front left tyre fitted incorrectly.
