Gary Hallberg stalked Tom Kite for two days and finally caught him on the 18th green yesterday, rolling in an eight-foot birdie putt for a one-stroke victory in the $300,000 San Diego Open.

The victory was the first for Hallberg and earned him $54,000. A dejected Kite, who missed a 25-foot putt for birdie moments before Hallberg's winning stroke, settled for $32,400.

"When I got over the putt I was shaking so bad and my heart was pounding," the 24-year-old Hallberg said. "It was so bad the putter was actually shaking. All I could do was get the putter back and let it go.

"The subconscious took over. I visualized the line the ball should follow and I guessed right. It followed that line right into the cup."

Kite and Hallberg were deadlocked at 16 under par through 71 holes on the tough south course of the Torrey Pines Country Club and both hit errant tee shots on the 501-yard, par-5 18th hole, Hallberg's ball landing in a trap and Kite's in heavy rough. Hallberg's wedge shot put the ball eight feet from the pin . . .

Australian Greg Norman won his second Australian Masters golf title in three years with a final-round 66 for a 285 in Melbourne. The four-stroke victory over Bernhard Langer of West Germany was worth $18,000.
