Tromp cleared outright waivers Wednesday and accepted an assignment to Triple-A Norfolk, Jake Rill of MLB.com reports.
Baltimore removed Tromp from its 40-man roster last Friday after Adley Rutschman was reinstated from the 7-day injured list in a corresponding move. Tromp will end up sticking around in Baltimore's organization and head to the Triple-A level, where he's slashed .182/.270/.341 with three home runs and 13 RBI in 100 plate appearances between Gwinnett and Norfolk this season.
