Graham Rahal was once again quicker than title rival Juan Pablo Montoya.
Verizon IndyCar Series teams were given another 45 minutes of practice Saturday after a 3.5 hour session on Friday.
Pocono winner Ryan Hunter-Reay led the way with a time of 1:16.8702. Championship contender Graham Rahal was second fastest, the same position he found himself in yesterday.
Points Leader Juan Pablo Montoya wasn't too far behind in fourth on the time sheets. Josef Newgarden was third and Scott Dixon fifth - two drivers still mathematically alive in the title fight.
Helio Castroneves, Carlos Munoz, Tony Kanaan, Will Power, and Simon Pagenaud rounded out the top ten. James Jakes was slowest, but just 1.8 seconds separated the entire field.
All 25 entires put down a time with Ryan Briscoe running the most laps at 18. Sebastian Saavedra spun early in the practice and later brought out the only red flag when he ran out of fuel.
Next up is qualifying at 3pm local time.
