Scott Dixon

How he got here: He’s always here. Dixon started slowly in the first two races (15th- and 11th-place finishes), but leaped into fourth in the standings with victory at Long Beach. He’s had two finishes out of the top 10 over the intervening 12 races.

For us to win last year was really cool. It was kind of our turnaround on the season to try to regain some strength on what started out to be a pretty slow start to the year. I’m excited that Team Target is still in contention for the championship with this being a double points race. Hopefully we’ll be celebrating with a lot of wine in Victory Circle for a championship and a race victory.”
