Larrazabal, 40, has been a force to be reckoned with so far on the DP World Tour this year.
The Spaniard won a few weeks ago in Incheon, South Korea for the Korea Championship. It marked his eighth career DP World Tour title.
This week, in the Netherlands for the KLM Open, Larrazabal entered the final round with a one-stroke lead at 10-under par.
He opened the tournament on Thursday with a solid 6-under 66, but followed it up Friday with a 1-over par 73.
He then rebounded Saturday with a 5-under 67 to set himself up in a solid position for Sunday's final round.
He went on to shoot one of the lower rounds of the day Sunday with an impressive 3-under 69. It was enough to win the tournament by two strokes over fellow Spaniard Adrian Ortaegui at 13-under par.
The victory, at Bernardus Golf in the village of Cromvoirt, marked Larrazabal's second DP World Tour win in his past three starts after the win in Korea.
It also marked the ninth DP World Tour title of his career.
Larrazabal is now one-step closer to making it onto his first ever European Ryder Cup Team, as well.
While the win didn't move him into one of the automatic qualifying spots, captain Luke Donald might not be able to ignore Larrazabal's dominance over on the European-based tour.
After a flurry of Ryder Cup legends resigned from the DP World Tour, spots have seemingly opened up for a new wave of European Ryder Cup stars.
And with two dominant performances just four months ahead of this year's iteration of the event, Larrazabal might've just locked up a spot as one of Donald's captain's picks.
If he does get selected, Larrazabal and the rest of the European Team will head to Marco Simone Golf & Country Club in Rome, Italy to face off against the Americans.
The tournament is set to begin 29 September.
