List of the closest NASCAR Xfinity Series finishes
From Wikipedia, the free encyclopedia
Like the NASCAR Cup Series, NASCAR's second-tier Xfinity Series has had many close finishes since electronic scoring was implemented in 1993. The current record for closest finish was set on February 17, 2018 during the 2018 PowerShares QQQ 300 at Daytona International Speedway, when Tyler Reddick defeated Elliott Sadler at a recorded margin of 0.0004 seconds.[1]
