Steve Ballesteros said the U.S. Professional Golfers Association made "a terrible mistake" in banning him from American tournaments.

"It was a thoughtless decision that can only harm international golf," he said during the Portuguese Open in Almancil. "It seems to me the PGA was under great pressure to take this stance. But I don't know where the pressure came from."

The U.S. PGA announced Thursday that Ballesteros, a past winner of the U.S. Masters tournament and the British Open, was barred from U.S. competitions for not having competed in the regulation minimum of 15 PGA tournaments.

"I don't contest the decision, but I believe the PGA has made a terrible mistake," Ballesteros said . . .

In Sydney, Greg Norman took a one-shot lead after the second round of the $160,000 Toshiba Australian PGA; his four-under 68 put him at six-under 138 . . .

In Kawanishi, Japan, Bobby Clampett of the United States shot a 67 for a two-round total of 135 to take the lead in the individual event while a nine-man Japanese team held a four-stroke lead over a team from the United States in the $302,330 '85 ABC Cup.
