Kyle Larson completed a sweep of the Sprint Cup Series’ practice sessions for Saturday’s Quaker State 400 at Kentucky Speedway, which airs on NBCSN.
The Chip Ganassi Racing driver recorded a speed of 178.412 mph in the final session, down from the top speed of 182.537 mph Larson put down in the rain-shortened session earlier Friday.
Larson was followed by Team Penske drivers Brad Keselowski (178.124) and Joey Logano (178.042). The top five was completed by Denny Hamlin (177.626) and Kurt Busch (177.357). Busch recorded the most laps around the 1.5-track with 74.
The final, 90-minute session was slowed once with less than seven minutes remaining when 2013 Kentucky winner Matt Kenseth spun out of Turn 4 and became stuck in the frontstretch grass. Kenseth finished the session 10th fastest (176.869).
