Tony Kanaan opened this weekend's IndyCar round at Pocono by setting the pace in the opening practice session.
Kanaan first moved into P1 in the opening minutes, and then reclaimed the spot from Marco Andretti with just over five minutes left on the clock. His 221.344mph lap - just a shade slower than the track record set by Andretti last year - stood until the end.
The driver who came closest to toppling the Brazilian was Ryan Hunter-Reay, who comes into the weekend looking to remain in contention for the Triple Crown by adding a victory on the 2.5 mile tri-oval to his Indy 500 win in May.
His 220.882mph effort, set on his final lap, was not enough to put him into P1, but it did allow him to leapfrog Andretti, who finished up third fastest.
James Hinchcliffe and Takuma Sato rounded out the top five, the latter moving up at the last moment to clear the time set Juan Pablo Montoya.
Helio Castroneves, who was the benchmark during the first few minutes, ended the morning down in 14th.
A largely uneventful session was interrupted by just two brief spells under caution, both of which were for track inspections.
