While Jordan Taylor slipped back to eighth, Karam, the reigning Indy Lights champion, subsequently drove the No. 01 to the second position, trailing leader Barbosa by less than two seconds at the midpoint of the 2-hour, 45-minute race.
With just over one hour, 10 minutes remaining, Karam surprised Barbosa with a daring pass and grabbed the lead before handing the car over to Pruett with 56 minutes left.
Karam’s pit stop for the driver change handed the lead back to Barbosa, who brought his No. 5 Corvette DP to pit road with 52 minutes remaining. After the stops cycled through, Barbosa led Pruett by nearly five seconds.
For his part, Pruett was trying to catch Barbosa while fending off Ryan Dalziel, who had driven the pole-winning No. 1 Tequila Patrón HPD ARX-03b/Honda into third place after teammate Scott Sharp had fallen back to sixth early in the race, thanks to the cars difficulty at the start and with the restart after the first caution.
Dalziel, however, spun in turn one of the 14-turn course as he tried to pressure Pruett and lost the third spot to the No. 90 VisitFlorida.com Corvette DP of Richard Westbrook as the top DP entries began to string out under the green. Barbosa extended his advantage over Pruett to more than seven seconds as the race hit the 2:15 mark.
After hounding Westbrook for the third position, Dalziel ran short of fuel with 13 minutes left and dropped to eighth in the running order, ultimately finishing fifth.
After Pruett and Westbrook made their late pit stops, the two drivers regained their second and third spots and finished there.
