Hoch finished regulation tied for the lead with Jim Furyk. The duo played the first playoff hole on Sunday but darkness kept them from completing the second hole.
Both players returned to the Blue Course at Doral Resort and Spa Monday morning and Hoch took the title with a birdie at the third extra hole. Hoch earned his 11th career title on the PGA Tour at the age of 47.

Phil Mickelson held on to third while Vijay Singh stayed put in fourth. Retief Goosen, David Toms, Davis Love III, Sergio Garcia, Mike Weir and Padraig Harrington all kept their positions from last week to round out the top 10.
Furyk, who was victorious at Doral in 2000, moved up two places to No. 11. He was followed by Hoch and Nick Price, who dropped two spots to 13th.
Chris DiMarco fell two places to 14th while Rocco Mediate dropped one to No. 15. Charles Howell III stayed put at No. 16 followed by Colin Montgomerie, who lost ground to fall to No. 17.
Robert Allenby came in at No. 18 this week with Jerry Kelly and Justin Leonard completing the top 20.
