Two days after dealing away two pitchers in the trade for first baseman Glenn Davis, the Baltimore Orioles got one yesterday, obtaining right-hander Jeff Robinson from Detroit for catcher Mickey Tettleton.

Robinson, 29, compiled a 10-9 record in 27 starts for the Tigers last year and will be remembered by Baltimore fans for carrying a no-hitter into the eighth inning of an 8-2 victory over the Orioles July 24.

Assuming no recurrence of the arm trouble that cost him large portions of the 1988 and 1989 seasons, Robinson figures to take the spot in the rotation that had been occupied by Pete Harnisch, sent to Houston Thursday with reliever Curt Schilling and outfielder Steve Finley.

"This replenishes our pitching in a hurry," said General Manager Roland Hemond. "We were fortunate to get a pitcher of his background and ability."

Robinson was enjoying a strong sophomore season in 1988 until he went on the disabled list in August, cutting his season short at 13-6 with a 2.98 ERA. He was 4-5 in 1989, when he had to spend time on rehabilitation assignment to the minors.

Tettleton had accepted the Orioles' offer of arbitration in late December, after he tested the free agent market and found no takers on his request for $7 million over three years. In finalizing the trade, Tettleton agreed to a one-year, $1.6 million contract with the Tigers, virtually doubling his 1989 salary and canceling arbitation, and a reported $50,000 from the Orioles for approving the swap.

Tettleton became the target of Memorial Stadium boos when he struck out a club-record 160 times last season while batting .233 and hitting 15 home runs. The strikeouts set a major league mark for a switch hitter.

Tettleton saw considerable duty as a catcher and designated hitter in large part because he was one of the team's few batters with power, having rapped 26 homers in 1989. But the addition of Davis and outfielder Dwight Evans made him expendable. Additionally, promising catcher Chris Hoiles now figures to get playing time he felt he was due last season.

"We were able to trade Tettleton because we have Chris Hoiles, who is deserving of a real good shot at major league opposition, and because {catcher} Bob Melvin just signed for two years," Hemond said.

"I'm excited about it," Robinson said. "I'm ready for a change. It's going to be nice pitching for a team where the outfielders are fast and good defensively."

As for pitching in Memorial Stadium, "Anyplace is better to pitch than Detroit, which is such a hitters' ballpark. But I don't pitch to the ballpark. I'll just throw it inside and let the fielders take care of the rest."
