DALLAS, DEC. 8 -- The second day of the 1987 winter meetings wasn't a good one for the Baltimore Orioles, who had one trade die and another couple appear to be falling through.

The Orioles' trade that would send pitcher Ken Dixon to Seattle for pitcher Mike Morgan fell through. Just as a news release was being prepared, Seattle owner George Argyros arrived in town and put it on hold.

It's the second time in three years Argyros has vetoed a Mariners-Orioles deal. The two teams were prepared to swap pitcher Storm Davis for third baseman Jim Presley when Argyros vetoed it. The Mariners' front office was hoping the trade could still be made, but the Orioles say they're shopping Dixon to other teams.

Meanwhile, a proposed trade that would send outfielder Mike Young to Detroit for outfielder Billy Bean and pitcher Mark Thurmond also was on hold as both team reassessed their positions.

If Young isn't traded to Detroit, he could wind up in Oakland. Sources said the Athletics will offer pitcher Gene Nelson and another player. The Orioles would prefer Bean, but apparently intend to leave here with at least one major deal.

They also appeared to have a slight chance of sending center fielder Fred Lynn to the Yankees. That's a long shot because the two sides haven't agreed to players, and even if they do, the Yankees will have to buy Lynn out of his no-trade clause.

Late Monday, the Orioles did complete one deal, acquiring veteran reliever Doug Sisk from the New York Mets for two minor leaguers. Earlier Monday, they drafted pitcher Jose Bautista from the New York Mets' Class AAA team at Tidewater.

Bautista and Sisk will join their 1988 pitching staff, but Manager Cal Ripken Sr. said, "I'm hoping to get some more experienced guys."

Other than the pitching staff, the Orioles were hoping to improve their outfield. Their plan now is to have Ken Gerhart in center, Lynn in right and Larry Sheets as a full-time designated hitter.

They're hoping to trade for a left fielder with decent speed, but they already have a backup plan. To give Pete Stanicek, a second baseman last year, a chance to learn to play left, the Orioles say they're considering asking Commissioner Peter Ueberroth permission to hold an early spring training session, perhaps as much as a week before the pitchers and catchers are scheduled to report.

The Orioles are unsure if Stanicek's arm is strong enough to make him a first-rate outfielder, but Ripken said, "Isn't he better than what we had? How many guys did we have out there last year who were throwing people out? The thing about him is we know he can run, and we know he can cut off some balls. We need that."

He said he might consider putting Sheets in left field if forced to, but said, "He just can't play right. He's not fast enough to cut balls off in the alley. He can get away with that in left. If you don't cut a ball off over there, the guy goes from first to second. If you don't do it in right, the runner goes from first to third."

Remember how the St. Louis Cardinals hoped that first baseman Jack Clark would be ready for the World Series? As it turns out, his ankle injury is so severe he might not be fully healed until mid-February. "Our doctors have sent him all over the country," St. Louis Manager Whitey Herzog said, "and they've found only two injuries like it. I remember on Wednesday, Sept. 9, they said he'd play Friday. I guess they meant Good Friday." . . .

The Houston Astros finished their two-year search for a shortstop by acquiring veteran Rafael Ramirez from Atlanta for two minor leaguers . . . The Detroit Tigers hired Pat Corrales to manage their Class AAA Toledo team . . . The Orioles and New York Mets will play an exhibition game at RFK Stadium on April 3.
