"This season has been very good so far but I'm looking to turn it into a great season," Suárez said. "We are moving in the right direction and I'm looking forward to doing even better.
"We've had strong cars over the last month and a half and hopefully I can do my part as the driver and make it a great race this weekend."
Austin Dillon posted the fastest average lap speed among drivers that completed at least 10 consecutive laps (180.639 mph). Hamlin and Hemric were second and third in that category, respectively.
