What happened
Polesitter Chase Briscoe pitted from the lead on Lap 35 during the opening green-flag stops at Homestead, but trouble changing the left-rear tire stretched his service beyond 16 seconds. Briscoe had led from the opening green flag before stopping for four tires and fuel. A separate engine failure later ended his race while he ran 7th. He finished 39th with 77 laps completed.
What it cost
The slow service cost Briscoe four positions, from the lead to 5th at the completion of the pit cycle. Christopher Bell took over the lead on Lap 43.
What could have been done differently
The Joe Gibbs Racing crew needed to complete the left-rear tire change cleanly.
