"I played quite a good round, it was a working round," Cabrera, a native of Argentina, said through an interpreter. "I had to work my way around. It was tough, the winds were picking up and the greens are getting very hard."
He ended 54 holes at the Sentosa Golf Club at 9-under-par 204 after a 1-under 70.
Jin Park of the United States (72) is second at 5-under 208.
