Garcia drove into the rough and with Larrazabal on in two again did wonderfully well to hit his second just short of the green, albeit in more rough.
He then chipped to three feet and with Larrazabal missing from 35 feet it was shared in birdies again.
This time, however, they crossed to the short 12th to try to settle it.
The third did not decide it either, Garcia lipping out from 20 feet and Larrazabal missing again from 14 feet.
It was the short 17th next and after Garcia missed from 15 feet Larrazabal failed from just inside him - and so they headed to the 18th once more for the fifth extra hole.
