Joey Logano held off a late charge from Team Penske team-mate Ryan Blaney to win a dramatic season finale at Phoenix and become a three-time NASCAR Cup champion.
Reigning champion Blaney found himself 2.3 seconds down on Logano entering the closing stages having battled past Hendrick Motorsports' Kyle Larson and William Byron but despite slashing the deficit, he never got close enough as Logano took the chequered flag.
