The hope was that he would make the leap to AAA, and potentially be available for a spot start in Florida or a back-of-the-bullpen job late in the season. The Marlins then sent Willis down to Carolina to work on consistency and control. Willis went 4–0 with a 1.49 ERA for Carolina. 2003 season On May 9, 2003, Willis made his major league debut for the Florida Marlins against the Colorado Rockies. He pitched six innings, allowed seven hits and three earned runs, and got a no decision. On May 14, in a start against the Padres, Willis went five innings, allowed five hits, three earned runs, and four walks, and received his first Major League win.
