Will Power, Penske, Baltimore 2012Will Power went quickest for Penske in the second abbreviated IndyCar practice session in Baltimore.

Delays once again hampered running while the series worked on mitigating the bumps that were causing cars to launch earlier in the day. Despite earlier hopes that the bumps could be removed by regrinding the affected area of the track, IndyCar elected to install a temporary tire barrier, with a permanent chicane set to be built overnight. The changes give the circuit a new official length of 2.03 miles.

Power christened the revised layout with a best time of 1:21.4572, nearly a half-second quicker than anyone else could manage. Schmidt-Hamilton's Simon Pagenaud was second, while Scott Dixon was third fastest ahead of early session leader Rubens Barrichello.

The half-hour session was interrupted by just one stoppage, with title contender Ryan Hunter-Reay bringing out the red flags after encountering problems early on. He was able to continue running once the session restarted.
