St. Pete: Power again fastest in final practice
 |
| Will Power |
Penske Chevy driver Will Power turned the fastest lap to lead the final practice Saturday morning as the teams prepare for Sunday's Firestone St. Petersburg GP IndyCar street race. After topping the Friday times, Power got down into the 1-minute range at 1m00.897s.
Jack Hawksworth was the only other driver in the 1-minute range with a time of 1m00.980s time in his AJ Foyt Honda.
Juan Montoya (Penske Chevy), Graham Rahal (Rahal Honda) and Helio Castroneves (Penske Chevy) rounded out the top-5.
The session was run without any major incident. The only red flag was Ryan Hunter-Reay who ran out of gas on the track and had to be towed in.
All 22 drivers were within 1-second of the leader, so the competition is very tight.
