Andreoli, 28, debuted in the bigs last year with the Seattle organization before landing with the O’s via waiver claim. That’s now reversed, though it remains to be seen whether he’ll keep his roster spot throughout the winter. Andreoli did not hit much in limited MLB opportunities, but posted a .287/.397/.401 slash in 388 Triple-A plate appearances last year.
As for Curletta, 24, the move will prevent him from achieving minor-league free agency. Primarily a right fielder during his prior minor-league campaigns, Curletta appeared mostly at first base last year at the Double-A level. He ended up posting a career-best output, with a .282/.383/.482 batting line and 23 long balls over 556 plate appearances.
