In 2008, Turnesa qualified for the PGA Tour. On October 19, he achieved his first PGA Tour victory by winning the Justin Timberlake Shriners Hospital for Children Open, finishing 25 under par. His check for $738,000 proved to be more than half of his total earnings for the year. Turnesa had one other top 10 finish that year, coming in second at the Viking Classic after losing to Will MacKenzie in a playoff.
As of mid-August 2009, he had started in 24 PGA events but had not finished in the top 25 in any. He had missed the cut in 15 events, and his best finish was a tie for 30th at the Northern Trust Open in February. His best round of the year was a 65 at the U.S. Bank Championship in Milwaukee.
