What happened
On Lap 93 at Homestead-Miami Speedway, Sam Mayer led the field onto pit road during the second stage break, but Haas Factory Team struggled with his right-front tire service. The stop lasted more than 20 seconds and dropped him to 18th.
Mayer recovered to 5th with 90 laps remaining. He later passed Carson Kvapil to regain the lead.
With 12 laps remaining, a flat right-rear tire forced Mayer to pit under green from 3rd. He finished 9th.
What it cost
The stop surrendered the lead after Mayer won both stages. His next stint at the front began on Lap 151.
What could have been done differently
Haas should have completed the right-front service cleanly to defend Mayer’s track position. Sheldon Creed took the lead by winning the race off pit road during the same round of stops.
