BALTIMORE, JULY 2 -- The day after pitching a four-hit shutout to beat the White Sox in his first major league start, Ben McDonald was still "walking on air."

McDonald needed only 85 pitches to become the first pitcher to throw a shutout in his initial start since the Cubs' Jeff Pico in May 1988 and the first Oriole to do it since Tom Phoebus in September 1966.

"It still hasn't sunk in," said the 6-foot-7 right-hander. "Maybe in November or December, I'll look back and say, 'Wow. I pitched a shutout in my first major league {start}.' "

McDonald said he was told by Manager Frank Robinson that he wouldn't be around for nine innings, "but the number of pitches I threw was more important. I just wanted to go as hard as I could for as long as I could."

Pitching coach Al Jackson said it was all he could do to keep McDonald, the first pick in the June 1989 draft, under control in the dugout.

"When Tim Hulett scored the first run {in the second inning}, Ben wanted to go out to the plate and shake his hand," Jackson said. "They must do that in college or something. I had to tie a rope to him to keep him down.

"But once he got out on the field, he wasn't overexcited anymore."Komminsk Waiting

Outfielder Brad Komminsk, designated for assignment Thursday when Brady Anderson came off the disabled list, continues to work out at Memorial Stadium.

If he is not picked up by another club by Wednesday, the Orioles will assign him to Class AAA Rochester. "Hopefully it won't come to that," said Komminsk, who batted .238 in 46 games with the Orioles.

Komminsk said he hopes to be claimed by another club, but that nobody had contacted him or Orioles General Manager Roland Hemond.

Komminsk also said the Orioles told him "they still want me in the organization because they think I can help them. But I'd rather be in the big leagues somewhere, to be honest.

"But if worse comes to worse, it's a great organization." And Finally . . .
