Franchitti, who earned his 33rd career pole to break a tie with Michael Andretti for sixth all time, was fifth fast (1:20.0677).
A Chip Ganassi Racing driver has won the past four races -- three in a row by Dixon and Charlie Kimball the most recent on Aug. 4 at Mid-Ohio Sports Car Course. Franchitti, who has 31 career victories, is seeking his first of the season.
Six different teams were represented in the top 10 of the warm-up. There have been nine different winners, including four first-time winners, in the 14 races. Up next is the Grand Prix of Baltimore presented by SRT on Sept. 1.
James Davison did not participate in the session as the Dale Coyne Racing crew was changing the Honda engine in the No. 18 entry. Davison, competing in his second IZOD IndyCar Series race, will incur a grid spot penalty for an unapproved engine change. He qualified 21st.
