With the victory – Mayer’s second in the playoffs – he becomes the first driver to lock himself into the Championship 4 at Phoenix in two weeks.
Saturday’s race was a seesaw battle as several title contenders ran into issues. Cole Custer, who led 114 of the 200 laps, hit the wall and was forced to pit with less than 50 laps remaining, which turned the lead over to Mayer.
