Sergio Garcia ended his three-year wait for a tournament victory by winning the Castello Masters by 11 shots in Spain.
The 31-year-old had taken an eight-shot lead into the final day and dominated again with a superb round of 63 on the Club de Campo del Mediterraneo course where he was boys champion aged 12.
Garcia, who was the tournament promoter, finished with his ninth birdie of the day for a 27-under total.
It gave the Spaniard his ninth European Tour career victory.
His compatriot Gonzalo Fernandez-Castano finished second after a 64 – although his round was spoiled slightly by two bogeys at the 17th and 18th while Scotland’s Richie Ramsay and Sweden’s Alex Noren were a shot further back on 15 under.
Garcia’s victory, his second in four years in the event, beat the previous biggest winning margin of the European Tour season by three shots.
