Pablo Larrazabal clinched the ISPS Handa Championship title by one shot on Sunday to land a DP World Tour trophy on Spanish soil for the first time.
Barcelona-born Larrazabal was tied for sixth heading into Sunday's final round in Tarragona, but a flurry of birdies propelled him into the lead.
That included a streak of five in succession from holes nine to 13, and though he bogeyed the 15th, he got that shot back on the following hole and gained another on the 18th to card a brilliant eight-under-par 62.
Having set the clubhouse target at 15 under, Larrazabal watched on as Adrian Otaegui (66), Hennie du Plessis (67) and Aaron Cockerill (67) all fell short.
Spaniard Otaegui finished at 14 under to take second place outright, with South African Du Plessis and Canadian Cockerill sharing third a shot further back, and Larrazabal has now won seven DP World Tour/European Tour titles, with this his second of 2022.
"What a day. But I knew that my golf was there," said Larrazabal.
"I couldn't make any putts the first three days, but I told my girlfriend last night that she had to choose the clothing for the pictures.
"I knew that I had a low one in my bag and that's what I did. Today I holed putts and that was key. To shoot 62 in windy conditions with the flags out there, it was good.
"I'm glad I got the seventh title at home. I live one hour and 15 minutes up the road and it's very special to win in Spain, in front of a few friends of mine, and obviously in front of my girlfriend and my brother.
"So it's not going to be the most emotional win in my career, but it's one of them. There were a lot of key moments today to keep that round going, and that hot stretch in the middle of the round was unbelievable.
"The golf I played on those five holes was probably the best golf in a long, long time."
Frenchman Antoine Rozner finished in fifth on 12 under, with China's Li Haotong two shots further back in sixth place.
