The Baltimore Orioles have signed reserve catcher Jeff Tackett and pitcher Francisco de la Rosa to 1992 contracts, but five of the club's six arbitration-eligible players remain unsigned.
Tackett, 26, appeared briefly in the major leagues last year, getting into six games and managing a hit and two walks in 10 plate appearances. His role is expected to increase in the wake of the December trade of veteran catcher Bob Melvin to the Kansas City Royals for pitcher Storm Davis, though the recent return of veteran backup Rick Dempsey has clouded the catching picture.
De la Rosa, 25, who led the Class AAA Rochester Red Wings with a 2.67 ERA in 38 games last year, spent the final month of the season with the Orioles, but was limited to two appearances by recurrent back spasms. His chances of starting the 1992 season on the major-league staff appear to be slight.
