He did not earn his Professional Golf Association Tour card for 2003 and returned to the Nationwide Tour that year where he played for two years before getting back his Professional Golf Association Tour card in qualifying school for 2005. Again he was not able to retain his card and returned to the Nationwide Tour in 2006.
He went through qualifying school for the third time and returned to the Professional Golf Association Tour in 2007 where he had his best year on tour, recording two fifth-place finishes and finishing 136th on the money list, earning him partial status on tour for 2008.
He split time between the Professional Golf Association and Nationwide Tour in 2008 and earned his Professional Golf Association Tour card for 2009 through qualifying school for the fourth time. He returned to the Nationwide Tour in 2010 and has been playing on it since.
