Otaegui took a six-shot lead into the final round at Valderrama and was never in danger of being caught, a closing 68 giving him a tournament-record total of 19-under-par at Valderrama on Sunday.

Sweden's Joakim Lagergren also shot a 68 to finish six shots behind, but Australia's Min Woo Lee could never get a final-round charge going as he ended with a 70 that left him another three strokes back in third.

Lee, though, has enjoyed an excellent fortnight on the Tour's Iberian swing, as he also finished third in last week's Open De Espana in Madrid.

Runaway winner Otaegui was one of three players added to the field for July's Scottish Open after they had appealed against their suspension for playing in the inaugural LIV event in Hertfordshire.

DP World Tour members who played on the Saudi-funded rebel circuit without permission were banned from the Scottish Open and hit with big fines.

But following a hearing before Sport Resolutions (UK), the suspensions imposed on Otaegui, Ian Poulter and Justin Harding were temporarily stayed, pending determination of their substantive appeals. The hearing is scheduled for February.

Otaegui played three of the first four LIV events but it is not clear if he will play any further tournaments.

"I feel so happy to have my first win in Spain, in front of these crowds, on my favourite golf course in Spain. It's just unbelievable, the week went perfect.” - Adrian Otaegui.

Speaking about his fourth European Tour title, the 29-year-old told Sky Sports: "I'm very, very proud.

"I feel so happy to have my first win in Spain, in front of these crowds, on my favourite golf course in Spain. It's just unbelievable, the week went perfect.”

Lee produced an explosion of brilliance over the fourth, fifth and six holes, which suggested he might be able to put some pressure on Otaegui.

When he holed for a third consecutive birdie, sinking a 43-foot putt on the 6th, he was elevated to 12-under momentarily.

But wayward driving, which had plagued his hopes all week, didn't help as he bogeyed the 7th, effectively ending any hope of a comeback triumph.

Spain's Angel Hidalgo was in tears walking on to the 18th green as fourth place ensured he sealed his Tour card for next season.

Queensland's Maverick Antcliff, the other Australian to make the cut, finished with a 69 that elevated him to joint-21st at level par for the tournament.
