The 22-year-old from Kalgoorlie repeated the feat in Race 2 as he took the chequered flag in a lights-to-flag drive from Franzoni and Fischer.
“I'm so happy to take the sweep at St. Pete and to come away from here with the championship lead,” said Martin.
“With the scholarship, there's a lot of pressure, but I thrive on pressure and that's one reason we've done so well this weekend.”
