LAST WEEK:Allgaier takes Phoenix Xfinity race to snap drought

LAST TIME: Austin Dillon passed Kyle Busch and Daniel Suarez on the final lap and surged to an improbable victory at Auto Club Speedway. Busch led 133 of the 150 laps, but the all-time Xfinity wins leader blew his left front tire while attempting to save fuel. Suarez briefly went in front while Busch attempted to keep racing on the sparking flat wheel, but when Suarez ran out of gas, Dillon, the 2013 Xfinity Series champion, roared to his then seventh career victory.
