National League President A. Bartlett Giamatti yesterday distributed a memorandum to team officials warning of possible player suspensions for "any act that is in my opinion intended to cause severe physical harm to an opposing player."

Reacting to a recent wave of six beanball incidents that caused bench-clearing brawls since June 13, he listed "intentionally throwing at a batter's head, fighting on the field or sliding with a 'rolling block' " as acts that could result in what he terms "the most severe penalties, including suspensions."

There have been eight bench-clearing brawls in the National League and six in the American League this season, including 10 in which the batter charged the pitcher's mound after either being hit or almost hit with a pitch.

The latest National League incident involved Andre Dawson's beaning by San Diego pitcher Eric Show on Monday. Yesterday, Dawson, in his first public comments since the incident, said he will make sure in his "own way" that Show doesn't forget the incident, which Show says was unintentional.

Besides Dawson, one other player has been hurt. Pitcher Joe Niekro of the Minnesota Twins suffered a shoulder injury when thrown to the ground during a game with the Milwaukee Brewers June 17. Dawson suffered cuts that required 24 stitches when hit in the face with the pitch by Show.

"It's not important whether I believe him or if he's sorry," said Dawson, holding an ice pack to the left side of his face during a clubhouse interview. "He says he is going to regret it for the rest of his life. I'll make sure he does regret it . . . Yes, I'm still bitter. I've got I don't know how many stitches and my face is still real swollen . . . What concerns me is when you challenge not only a man's livelihood but his life."

He said he hasn't talked to Show and doesn't expect to face him when the Cubs play at San Diego next weekend. "If they {the Padres} are wise, they won't start him," Dawson said. "I understand they aren't going to let him face me."

As a sinker-ball pitcher, Dawson said, Show had no reason to throw high and inside against him.

Dawson, whose 24 home runs and 74 RBI lead the club, said he is still woozy when he awakens but hopes to resume playing this weekend and expects to be able to start in the All-Star Game Tuesday in Oakland.

After being hit, he lay motionless three minutes before getting up and charging the mound; Show already had been escorted to the San Diego dugout.

"They say I was out of it for a couple of minutes," Dawson said. "It didn't seem that long. My reaction, to be honest, was to get him. I don't know what I would have done had I gotten him. I haven't thought about it."

Bobby Brown, president of the American League, said he plans no similar memo to Giamatti's. But American Leaguers contemplated the problem.

"I think the American way is to defend yourself," third baseman Ray Knight of the Baltimore Orioles said, "and when a guy hits you with a pitch, it's a natural reaction to {retaliate}. That guy is throwing a ball that can kill you. He could end your career, and careers have been ended. I see nothing wrong with pitching inside or even hitting a guy in the butt or leg, but when you're talking about a guy throwing for your head, that's something else . . .

"I saw Dickie Thon get hit in the face with an 0-2 pitch by Mike Torrez, and it ruined his career. Maybe he meant to do it, maybe he didn't. But what should the punishment be for that?"

Coach Frank Robinson of the Orioles wondered how Giamatti could make a judgment unless he sees the incident.

"I think it has to be up to the umpires," he said. "They're there. They're involved in the emotions. You can't always tell what's going on just by looking at tapes. If he should do anything, it's give umpires a little more authority. They're the ones who know who should be suspended."

"The game of baseball is, of course, a physical one, highly competitive, involving contact," Giamatti said in his communique. "It must be played hard and aggressively. It must also remain baseball and not become something else.

"Beanballs and similar acts are highly unsportsmanlike. They are dangerous. They must stop. Acts clearly intended to maim or injure another player have no place in a profession that wishes to maintain its dignity and its credibility with the general public."

Don Fehr, executive director of the Major League Players Association, said that the players association would object only if any suspensions were considered extreme. He said the players association could reopen negotiations on the collective bargaining agreement because of Giamatti's memo, but that "the odds of it coming to a confrontation are very low."

Fehr said that, during the recent negotiations, the two sides tried to see "if some sort of modification could be worked out on the beanball rule because the first guy gets a free shot {at throwing a beanball}." But Fehr said that negotiators were unable to come up with a solution.

Under current rules, a pitcher who throws a beanball in retaliation is subject to ejection, as well as his manager.

Fehr said that the beanball has been part of baseball "as long as I've been around and probably for 80 years." He said he would be surprised if it were more prevelant this season than in the past. A National League spokeswoman said the league does not keep such statistics; an American League spokeswoman said there were eight such incidents in that league in 1986. Correa Disabled
