Jimenez routed flu-ridden David Lynn 6 & 4, highlighting five final-day singles wins for the continentals, who broke a streak of six straight losses in the event.
The closing-day blitz came after GB&I had rallied to pull even at 9-9 thanks to some clutch performances in Saturday's foursomes.
After Jimenez won to put the continentals ahead, Matteo Manassero followed with a victory and Francesco Molinari later clinched the triumph in the final singles match with a 3 & 2 defeat of Chris Wood at the Saint-Nom-La- Breteche course.
