Scott Dixon will reach a landmark in his Indy car career on Sunday in the Honda Indy 200 at Mid-Ohio.

Should he start the race, the four-time Verizon IndyCar Series champion and current points leader will become just the ninth driver to compete in 300 races. Dixon, who turned 38 on July 22, will be the youngest to reach the milestone, joining legends Mario Andretti, A.J. Foyt, Al Unser, Al Unser Jr., Johnny Rutherford and Michael Andretti, as well as contemporaries Tony Kanaan and Helio Castroneves.

Dixon scored the 44th win of his career in the most recent race, the Honda Indy Toronto on July 15. He's becoming used to having his name mentioned with Indy car’s all-time greats. As he heads to his most successful track -- Mid-Ohio Sports Car Course, where he owns five wins -- Dixon trails only Foyt (67) and Mario Andretti (52) in career wins and podiums (Andretti 144, Foyt 119, Dixon 102) and is tied with Foyt for second all time with 149 top-five finishes. Andretti heads that list with 194 top-five results.

While comparison is largely subjective, should Dixon win his fifth Verizon IndyCar Series title this year, he would surpass Andretti (among others) and trail only Foyt (seven) in total Indy car season championships.

But how does the Chip Ganassi Racing driver stack up with Indy car's greatest duo at the time they made their 300th starts? Foyt was 12 years older than Dixon when he made his in the 1985 Indianapolis 500. Andretti was 10 years older than Dixon when he started his 300th race at the 1988 Indianapolis 500.

The following graphs compare the accomplishments of Andretti, Foyt and Dixon at career start No. 300. Dixon, of course, could add to his lofty numbers in Sunday's Honda Indy 200 (3 p.m. ET on CNBC and Advance Auto Parts INDYCAR Radio Network; encore telecast at 6:30 p.m. on NBCSN).

Dixon knows he has miles to go before matching either Andretti or Foyt in career wins. But still in the prime of his career and with one of the top teams in the INDYCAR paddock, plenty of trophies can still be attained.

“I think A.J. is pretty safe,” Dixon said of Foyt's amazing 67 victories. “He's a long way ahead. I think for us, we take it race by race. We're in the business of winning races. If we're not doing that, I won't have a job for too long. That's the focus for right now.

"Right now with 44 wins, next on the list is Mario at 52 or something. We'll see how it goes. Eight (wins) is an infinity away.”

Only time -- and more races -- will tell if it's infinity and beyond for Scott Dixon.
