Donny Schatz Trying For 27th Straight Knoxville Nat'ls A-Main

 WATCH: Donny Schatz charged from 15th-to-fifth in Friday's Knoxville Nationals Hard Knox Night but will have to start 11th in Saturday's B-main.

Starting Lineup For Saturday's Knoxville Nationals A-Main

Twenty of 24 starters are set for Saturday's 64th annual NOS Energy Drink Knoxville Nationals presented by Casey's as 18-year-old Ryan Timms will officially lead the 50-lap $195,000-to-win feature to green.

Timms's 487-point night Wednesday where he won and racked up plenty of qualifying (third of 51) and heat (eighth to fourth) points ended up four markers better than Carson Macedo's 463 total. Macedo, who finished fifth Thursday, needed to finish second or better from the eighth-starting spot Thursday to earn the pole.

Logan Schuchart's runner-up and Brad Sweet's 21st-to-eighth run Thursday lock them into Row 2 while Sheldon Haudenschild's podium and Corey Day's 21st-to-seventh run Wednesday put them in Row 3. Rico Abreu and Emerson Axsom make up Row 4 while Thursday's winner Kyle Larson — slightly hampered by qualifying 15th and only going sixth-to-fourth in his heat — and Wednesday's runner-up Justin Peck are in Row 5.

Garet Williamson, Austin McCarl, Bill Balog, Giovanni Scelzi, Cameron Martin and Spencer Bayston are the final top-16 lock-ins. Chris Windom and Brent Marks will lead Saturday's B-main to green.
