Stewart-Haas Racing driver Kevin Harvick was not satisfied with the No. 4 team's pit stops during Sunday's race at Dover International Speedway, and he let the crew know over the scanner.
"We need to learn how to make a (expletive) pit stop," he said at one point. "Track position means a whole lot."
Harvick led 116 of the opening 120 laps, but was shuffled back during a spate of four caution flags from Lap 120 to Lap 185.
Responding to a jab on Twitter, crew chief Rodney Childers hinted at a possible reason why.
Because Harvick won at Phoenix earlier this year, he is all but locked into the Chase for the NASCAR Sprint Cup. Many Chase-qualified teams test different setups in order to learn for the postseason, so it would make sense for the experimentation to spill over onto pit road as well.
