Brent Marks maintained a slight advantage over Danny Dietrich in the National Sprint Car Rankings heading into this week’s Knoxville Nationals at Iowa’s Knoxville Raceway. Marks boasts an average finish of 4.4 in 54 starts this season, while Dietrich has an average finish of 4.480 in 61 starts. However, Peck has reached the 65-start limit and can no longer drop his worst finishes. At 65 races, Peck has more 410 events under his belt than any other driver in the nation. Anthony Macri is fourth in the rankings and World of Outlaws point leader Brad Sweet, who won the Ironman 55 over the weekend, ranks fifth. Sweet has only started 48 races and can begin dropping his worst finishes after he reaches 50 starts.
