Marco Andretti opened this weekend's IndyCar round at the Milwaukee Mile by setting the fastest time in today's opening practice session.
Andretti moved to the top with a lap of 21.9217s just over 10 minutes before the end of the session to lower the previous marker set by team-mate Ryan Hunter-Reay by just 0.0183s, and the time remained unbeaten.
Josef Newgarden finished up with the third-fastest lap ahead of Tristan Vautier and Will Power on a morning where the top nine were covered by 0.1s.
The session was interrupted by just one brief caution period when James Hinchcliffe scraped the wall at Turn 2, but the Canadian quickly returned to the pits under his own power and finished the morning with the 10th-fastest time.
