Weekley ends five-year drought with Colonial win
Kuchar (68) birdied the parfour 18th to finish alone in second place, a stroke ahead of former Masters champion Zach Johnson (66).
Scott Stallings ( 66), John Rollins (68) and Matt Every (69) were all a shot further back in a share of fourth place.
Jordan Spieth, the 19-year-old from Dallas who has played three of the last four years at Colonial, tied for seventh at 10-under.
“I’m extremely pleased with my round,” Spieth said. “I could have very well won this golf tournament.”
Weekley’s last triumph before Sunday had come at the former Verizon Heritage, now known as the RBC Heritage, in 2008 before he was hit by injuries and a run of poor form.
Weekley, who helped the Unites States capture the Ryder Cup in 2008, showed flashes of his ball striking ability at Colonial, hitting more than 71 percent of his fairways and 75 percent of his greens in regulation.
His putting was also sharp and a 21-footer on the 13th green helped him to the long awaited win.
Idoki wins Senior PGA title after Perry collapse
Meantime, Japan’s Kohki Idoki clawed back a five-stroke deficit to win the Senior PGA Championship on Sunday following a final round collapse by Kenny Perry.
Idoki shot a final-round 65 to vault past the field on his way to a two- stroke victory at the Bellerive Golf Club in St. Louis. The 51- year- old charged with four birdies on the front nine and two more on the back to finish on 11-under-par 273.
It was more major disappointment for Perry, who endured playoff defeats at the 2009 Masters and 1996 PGA Championship.
The 52-year-old ended on nine under, tied for second with Jay Haas and just ahead of Mark O’Meara ( eight under) and Kiyoshi Murota (seven under).
Perry had entered the final round with a two- stroke lead and built momentum with three birdies on his first five holes before falling apart on the back nine.
He made a double bogey on 13 that dropped him into a tie with Idoki, then fell out of the lead with a bogey on 16 and added another on 17.
