An incredible final lap of the Straight Talk Wireless 400 from Tyler Reddick clinched his place in the Championship 4 in Phoenix next month.
The #45 car looked all but out of the running when racing with a massive tyre deficit and about to run out of fuel inside the last 20 laps, but a late caution for a dramatic Kyle Larson slide bunched the whole field up and prompted a shootout on fresh tyres for the last handful of laps after the restart, with the front of the field entirely made up of championship hopefuls.
Reddick was running third with a lap to go, but shot past Denny Hamlin in the first corner of the final lap to set himself up to take a brilliant run around the outside of Ryan Blaney, who had looked destined for the victory after fighting through from 20th on the grid.
The top six finishers in Miami were all playoff contenders, highlighting both the high stakes ahead of the final qualification race next weekend and just how fine the margins of error were for Reddick as he stunned Blaney and the #12 team.
Teams will now head to Martinsville, Virginia for the final race before the Phoenix shootout, with the Xfinity 500 set to provide the final two places in the Championship 4.
