The Belgians were steady, and used a series of angled volleys to earn their own chance. Dodig, chasing his third men's doubles major, diffused the danger with perfect shot placement.
The Croatian crushed a forehand on the rise and Krajicek's smooth net play forced the vital error as they stole a 5-3 break lead.
Spurred on by a Player's Box full of friends and family, Dodig and Krajicek demonstrated why they have become such a lethal partnership, roaring through seven of the last eight games of the match to kick-start the celebrations.
Dodig had been confident that they could lift the title on Saturday, which was evident from his flight itinerary.
"It's definitely going to be a late night, I already planned for this. I was not cocky, but I was confident, so I booked my flight on Monday," admitted Dodig.
"So tomorrow I can recover from tonight. We have a lot of friends and family here, so it's time to get some good dinner, some drinks, then back home before London."
