Michael Thorbjornsen withdraws from Wyndham after first PGA Tour win

Just hours after winning the Rocket Classic in Detroit for his first PGA Tour victory, Michael Thorbjornsen withdrew from the Wyndham Championship on Sunday night.

The 24-year-old Stanford alum shot a career-low 63 in the final round to erase a four-stroke deficit at the start of the day and get into the winner's circle in his 65th career Tour start. The 500 FedEx Cup points lifted him from No. 69 in the season-long standings and just inside the cut-off line for the playoffs to No. 31 and safely into the BMW Championship.
