If the morning warmup is any indication, could this be the day Scott Dixon finally breaks his Barber Motorsports Park hex?

Six-time NTT INDYCAR SERIES champion Dixon led the 30-minute final practice Sunday morning before the Children’s of Alabama Indy Grand Prix powered by AmFirst, turning a top lap of 1 minute, 6.6933 seconds in the No. 9 PNC Bank Chip Ganassi Racing Honda. Dixon has nine podium finishes in 15 starts at Barber – but no victories.

There is one catch for Dixon today, though – continued qualifying woes. Dixon is starting 13th for the 90-lap race (1 p.m. ET, FOX, FOX One, FOX Sports app, INDYCAR Radio powered by OnlyBulls). Still, this is Dixon’s best starting spot of this young season after qualifying 16th at St. Petersburg, 15th at Phoenix and 20th at Arlington.

Graham Rahal reaffirmed the speed he showed while qualifying third Saturday, ending up second in the warmup at 1:06.7568 in the No. 15 Fifth Third Bank Honda of Rahal Letterman Lanigan Racing. Felix Rosenqvist, who starts 18th, was third at 1:06.9815 in the No. 60 SiriusXM Honda of Meyer Shank Racing w/Curb Agajanian.

Nolan Siegel was fourth at 1:07.0619 in the No. 6 Arrow McLaren Chevrolet after qualifying 15th on the 17-turn, 2.3-mile road course. Marcus Armstrong, who qualified fourth, stayed in the same speed neighborhood by rounding out the top five at 1:07.0883 in the No. 66 SiriusXM Honda of Meyer Shank Racing w/Curb Agajanian.

NTT P1 Award winner Alex Palou ended up seventh in the warmup at 1:07.2859 in the No. 10 DHL Chip Ganassi Racing Honda.
