Persistent rain forced NASCAR officials to ending race Miami Speedway.
Truck teams were able to practice for the Ford 200 before rain fell on the 1.5-mile South Florida track. James Buescher was awarded the pole position since he was the quickest in practice. Ty Dillon will start alongside Buescher on the front row.
Nelson Piquet Jr. and Austin Dillon, the current points leader, will share the second row, while Johnny Sauter and Cole Whitt will occupy row three.
Ron Hornaday Jr. will start 22nd in what will be his 300th race in the series.
Dillon holds a 20-point lead over Sauter and a 28-point advantage over Buescher. If Dillon -- the grandson of NASCAR team owner Richard Childress -- finishes 16th or better at Homestead, he will wrap up the championship, regardless of any other driver's performance. He would also clinch the title if he finishes 17th or better with at least one lap led...or 18th or better with the most laps led.
Tim George Jr., Ross Chastain, Brennan Newberry, Derek White, Dennis Setzer, Frank Kimmel and Jeff Agnew did not qualify.
The 200-mile race at Homestead is scheduled to start just after 8:00 p.m. (et).
