Garcia, the tournament's host pro at the Costa Azahar golf club in Castellon, Spain, completed the round with a total of 16-under 197, and Sunday bids for his first European tournament win since the 2005 European Masters.
His up-and-down round Saturday included eight birdies and two bogeys.
"I am trying as hard as everybody else is, but fortunately for me I'm doing a little better than everybody else is," Garcia told reporters. "We're here to try to win like everyone else is, and I'm just happy to be in a good position at the moment."
Denmark's Soren Kjeldsen (70), who held a piece of the lead after the first and second rounds, shares second place at 12-under 201 with England's Simon Dyson (68) and David Lynn (68) and Peter Hedblom (68) of Sweden.
