He led by two after Thursday's opening 18 holes.
In Friday's second round, the two-time U.S. Open winner shot 4-under-par 68 and his 36-hole total, 12-under 132, leads Denmark's Soren Kjeldsen (65), who birdied two of his last four holes.
"The greens, especially the first nine, the greens were excellent to putt on," Goosen said about his round. "I didn't really give myself that many chances (but) I'm happy where I am. I'm sure it will be close to leading on the end of the day and see what happens."
England's Nick Dougherty (65) and Scotland's David Drysdale (64) are tied for third at 10-under 134.
Among those failing to make the 3-under 141 cut were Scotland's Alastair Forsyth (142), Ireland's Paul McGinley (142), America's John Daly (144) and Germany's Martin Kaymer (147), the defending champion.
