Power leads first Baltimore IndyCar practice

Penske's Will Power opened this weekend's IndyCar Series round in Baltimore by going fastest in the opening practice session.

Power's best time of 1m20.8632s came on his final timed lap, and put him 0.2 seconds ahead of Andretti driver EJ Viso. Prior to his final run, the Australian's major impact on the session had been a near-miss with the barriers after being launched off the exit of the chicane.

Oriol Servia, Graham Rahal and Scott Dixon completed the top three on a morning punctuated twice by red flags. The first came when Stefan Wilson, making his debut in the second Dale Coyne Racing entry, went off the road at Turn 5, and the second was triggered a short time later by debris.

Target Chip Ganassi Racing's Dario Franchitti was restricted to just five laps after his car developed a sensor problem.
